The first thing you notice when the box shows up on your door is that it's very big. The cabinet feels very well constructed. The look of the face (with the cover removed) is a fo-carbin fiber look. Everything about this feels well made.
My pervious `home theater' had been a $250 system in a box (receiver, speakers, and sub). That old system had an 8 inch sub that was probably

This is a great deal for $59 delivered. I don't know what I was expecting. Maybe some hollow sounding computer type sub-woofer that pops when I turn it on and off. This sub has a 50-watt RMS amp at 5ohm. It has a decent .5 inch MFD box with an internal space of almost 10.5 X 10.5 (small!) External is about 11.4 x 11.4 x 11.5 height. It's much better built than the Sony's on this site. They even made a small attempt to support the box with 1-inch corner braces on all 6 sides. The sub sounds great at lower volume. It maxis out fast though. In a small room or apartment, you wouldn't need it any louder. It's the quality of sound that's important, and that's where this delivers. Up to it's distortion point, it sounds like a true big sub-woofer. This is the perfect sub for anybody who is not allowed to shake the foundation. This sub plays deep! It just hits its max excursion fast. Either the amp is more than 50 watts or the speaker can't handle much wattage. Speaking of the speaker, it's about 5lbs. They seemed to have glued a smaller magnet onto the larger one at the base. I've heard of some seedy speaker manufactures doing this, but this speaker seems to deliver pretty good quality. I swapped out the stock speaker with a Dayton and secured the walls with cross braces and then covered the inside walls with carpet. Foam would take up to much space and there isn't much inside already. This setup was a pleasure to work with. The grill pops right off. The speaker is held on by 4 screws in the standard speaker hole location. (making it easy to replace) The amp is held on by 8 screws. The port is held in place mostly by a tight fit and some glue that easily breaks loose. The amp is connected to the speaker with standard removable connectors. That's it. It takes about 3-5 min to take apart. As for the Dayton, it performs about the same as the stock one. It was made for a little bit bigger box, but I wanted to know if the stock speaker was unable to handle much or was it the amp that produced the power. It seems to be the amp. It can push a stronger speaker. If I had a 100 watt 8" speaker with a high SPL, built for a small-ported box, and good excursion level (that's the amount of movement on a speaker), then I would really need the extra bracing. Problem is, that would cost much more than this whole system. That, and I wouldn't use a .5-inch thick box. Where am I going with this... anyway, this sub is worth every penny of $59. If you have a set of decent bookshelf speakers and a sub-woofer out jack on your amp that you're not using, you would be a fool not to get this. To cut costs, it has no auto on/off, and no pass through signal. If you must have auto on/off, buy a remote control on/off power supply from someplace cheap. I had one left over from my X-mass lights. (or use the power connection on the back of your receiver if you have one). This sub doesn't pop at all when turned on or off and its amp is inside the box. This sub is much better looking than a Sony I have. If the person before me didn't didn't give this 4 stars, I wouldn't have tested this out. So thanks! I'm very happy I purchased this. I think its so cheap people are afraid of it! I don't know how they make money on this. (update 1-11-08) to clarify the wattage on these: output power on the spec sheet is rated at 5ohms. 50 watts to 5 ohms RMS and 100 dynamic. It has a 6ohm speaker in it. That means it's probably pushing about 45 watts RMS to the speaker. The frequency response is -4db at 40hz, -10db at 30hz, -15db at 25hz. It has a decent flat response from 45hz to 120hz at 90db. It then tapers off to -5db at 200hz. Not bad for $59 !!! Update 1-15-07 Here's a FYI given to me: The second magnet glued on the back of the driver magnet is for shielding. It is not there to deceive. The second magnet is attached in polar opposite to the functional magnet, canceling the magnetic pollution it would normally give off. (Thanks Kevin!)

JBL ES90BK 4-Way, Dual 8-Inch Floorstanding Speaker - Black Review

JBL ES90BK 4-Way, Dual 8-Inch Floorstanding Speaker - Black
Average Reviews:

(More customer reviews)
See 3/19/2010 update below.
I'll start by saying that my 3 rating would be about a 7 on a 1 to 10 scale. Based on the overly strong midrange and the fact that JBL is having this speaker built in China, I can't give this a 4 out of 5.
Fit, finish, and appearance on this speaker is somewhat mixed. The front panel veneer is attractive and rolls to the top panel via the beveled edge at the top front. The front panel is made of MDF and appears to be either 3/4 or 1 inch thick. It sounds very solid when rapped with your knuckle. (This is a simple and quick test I would recommend for any speaker.) In general the front of the speaker looks very good.
The side panels are thinner MDF and have a plain black veneer with a fine texture. I can't tell whether they are 1/2 or 5/8 inch thick. The entire cabinet tapers from front to back, with the back only measuring 7 1/2 inches wide vs. 10 1/4 at the front. This tapered design isn't my first choice, but others may like it. The speakers have outboard feet pre-installed which yield good stability despite their height. If you don't like the looks you can install a set of inboard feet that is included in the box.
The bass port is fairly low on the back side just 5 inches above the bi-amp capable sets of binding posts for the speaker wire. These posts are really too close together for easy loosening and tightening, and the bottom pair is further hampered in this regard by their proximity to the panel that holds the posts. The posts include a set of preinstalled gold jumpers for when you are not bi-amping.
I'm using a Kenwood KR-V8080 receiver in stereo mode to drive these. I'm just listening to music with them and my source is a PC with HD audio sound built in (Analog Devices SoundMAX) and iTunes. Nearly all of my music is from CDs imported to Apple lossless compression, so I should be getting the same quality as using a CD player. I'm open to comments about possible shortcomings of this setup, but keep in mind that Apple lossless is just that, it gets decompressed on playback to the same bitstream as was on the CD. I'm not basing the review on any compressed material.
I've listened to a wide variety of rock, pop, and country music at this point, including some remastered material with excellent sound quality. (I have not listened to any classical or jazz.) I could go into details on particular tracks but it wouldn't change the big picture, which is that this speaker has a pronounced midrange that must be cut to really be musical.
I am using a 10 band Audio Control equalizer to unlock the potential of these speakers. You should be able to do the same with a software equalizer of some sort if the PC is your music source. What I have found to be the best is to cut the mids (500, 1000, and 2000 Hz) from 4 to 6 dB, and boost the treble sliders (4000, 8000, and 16000 Hz) by similar amounts. The bass needs a boost as well but it will vary based on the source CD and the placement of the speakers in the room. My listening room is fairly large as part of a combined living room / dining room that also joins into the foyer in a very open plan. The speakers are about 16 inches from the wall behind them but quite a ways from the side walls, and 7 feet apart.
The net result in a comparison between equalized and non-equalized is dramatic. The non equalized sound is very flat and overly 'warm', with vocals usually sounding like they're inside a muffled can. It's worth noting that I prefer a human ear sensitivity curve output for most sound systems and source material. I don't know if I've needed to apply 12 dB of difference between the highs and the mids though.
The sound with equalization ranges from good to very good. I can't yet say it's excellent. It is very clean and the bass is tight if you're not trying to shake the house too much. My 4 out of 5 rating on sound quality is based on the equalized version.
What I have noted with these JBLs is that the sliders I am cutting all are in the frequency range covered by the 4 inch midrange transducer. Whether JBL intended for these speakers to have such a strong midrange, or they've had some sort of manufacturing process control issue with their crossover network, I doubt that many listeners would disagree that bringing the mids down a good bit yields a much better sound. If out of the box they sounded closer to what they do with equalization I would give them perhaps an 8.5 out of 10, so consider that against the 3 out of 5 overall rating I'm giving here.
If you're going to use these for a high end home theater system you will need a subwoofer to really feel the low stuff, but for many users these will be enough and a sub won't be necessary. A 36 Hz -3 dB point is going to cover most everything but the low bass and earth shaking sound effects.
I have owned 3 other pairs of JBL speakers (including the L60T from the late 80s) and have listened to a few more, and this is a departure for JBL's normal tendencies in my experience. My L60T's are very bright and clean in the high range and the mids are not nearly as strong. The L60T is a 2 way design with a 1 inch titanium dome tweeter that must cover much of the midrange as well, so I was quite surprised that the ES90's 4 way design (with 2 specialized tweeters) also needs at least 3 dB more treble boost to come close to it. I'm still not sure it equals it. I'll update this review if my opinion changes. (In the past I've also auditioned Infinity, Polk, Boston Acoustics, Klipsch, and Bose. The best speakers I ever heard were some Infinity Reference Standard 4.5's back in the 80s. I've never been impressed much with the Klipsch I've heard, Polks I've heard were laid back and mellow, while the old JBL and Infinity speakers were very upfront and in your face with their pronounced and very clear high end.)
(For the argument against using equalization because it's not 'how the music was intended to sound', I would ask in what room? With the speakers positioned where? And which speakers? With which mastering? If you haven't tried using an equalizer or at least a 3 band setup with Bass, Midrange, and Treble controls, give it a try and cut the midrange. In general it will give the sound more depth and make it more listenable at both low and high volume levels. While it seems logical that simply boosting bass and treble would work, in my experience it doesn't work as well without a midrange control. The general shape of the curve I'm applying with the equalizer is consistent with many software equalizer presets for Rock and other music types, including some of the iTunes preset curves. The ear is most sensitive to midrange frequencies, and less so for the high and low ends. This is true for the audible threshold as well as the max you can listen to. Loudness controls offset this sensitivity for low listening levels by boosting bass and treble.)Update 3/19/2010:
I've just sent these speakers back. In comparison to my 20+ year old JBL L60T's, the old speakers are just clearly better. There is no doubt that the 1 inch titanium dome tweeters that JBL used for many years (including in the L60T, L80T, and L100T from the late 1980s) is better than the two tweeters in the ES90 put together. And the single 8 inch woofer in the L60T (with surrounds just recently replaced on both speakers) is not really giving anything up to the dual 8 inch woofers in the ES90. All in all a big letdown for me as a loyal JBL user.
I'll also downgrade my overall 7 out of 10 to perhaps 6.5 out of 10, and downgrade the equalized score to 7.5 out of 10.

Yamaha YST-SW315 10-Inch Digital Pro Series Subwoofer (Black) Review

Yamaha YST-SW315 10-Inch Digital Pro Series Subwoofer (Black)
Average Reviews:

(More customer reviews)
I picked up the Sony 8" (SA-WM250 100-Watt) Active Subwoofer recently, and it's quite nice (especially the price at under $100.00). But this smaller system can't hold a candle to the Yahama. This 10" system pumps out clean, crisp base and its cut-off option allows the user to limit the higher frequency response of the sub-woofer (and let your mid-range speakers do the job). The result - a pretty massive, well defined bottom that can be as subtle or as "in your face" as you like it and which will nicely compliment just about any existing audio/visual system.
Because I use a pair of smaller AAD speakers, I keep the volume level for the subwoofer at below 50%, but the frequency cut-off a bit higher (110 hz out of max 140hz) for a nicely balanced, very full sound. Another nice feature is a bass button selection for either (i) music, or (ii) movies. The latter provides maximum bass response - suitable for achieving something similar to what you get in movie theatres - the rumbling bass that lodges in your stomach. The former, music option, is ideal and very complimentary to my existing stereo arrangement.
If you're unhappy with the response of your shelf speakers (want more oomph?), you'll love this Yamaha subwoofer. It'll add depth to your existing system, and add real luster to your audio-video setup. I recently re-watched "The Two Towers" on DVD using the Yahama - the experience was truly like a return to the theatre.

Yamaha's YST-SW315 offers 250 high-efficiency watts--enough power to deliver shattering, movie-theater-like bass effects. Full enjoyment of Dolby Digital and DTS surround sources requires deep, clear bass. This is especially true with 5.1- and 6.1-channel sound, because the ".1" channel is dedicated to the bass frequencies. That means you not only need a subwoofer, but a high-power subwoofer capable of handling extremely low frequencies. The YST-SW315's down-firing 10-inch driver translates power into clean bass sound, and the YST-SW315 boasts a frequency response of 20 to 160 Hz (-10 dB at the extremes of the range).The YST-SW315 delivers high power at deep bass frequencies, with excellent stability and low power consumption. This is made possible by the sub's highly efficient PWM (pulse-wave modulation) digital-drive power amplifier. The amplifier achieves superior conversion efficiency by minimizing power loss from the power transistors. It delivers stable audio power while minimizing AC power consumption and heat production. As it requires no output filter coil, it's extremely quiet with low distortion.Yamaha's patented Advanced Active Servo Technology (Advanced YST) generates incredible bass from small speaker enclosures. This system uses negative-impedance feedback in the amp and a Helmholtz resonator in the speaker to provide strong and accurate bass.QD-Bass (Quatre Dispersion Bass) technology uses a down-firing driver with square, pyramid-shaped reflective plates to radiate sound efficiently in four horizontal directions. The reflective plates (not used in other brands' down-firing subwoofers) negate any effects caused by the floor surface and reduce resonance between sound waves reflected from the floor and the unit. Most other systems use circular cones, but the YST-SW315 avoids firing sound into the legs of the cabinet by radiating in four directions. Changing the height of the pyramid varies the acoustic load, permitting relatively simple high-cut adjustment and improving bandpass properties. QD-Bass also grants greater freedom of placement, since the sound radiates with equal effectiveness in all directions.The user-adjustable, continuously variable high-cut filter sets the highest frequency the subwoofer will deliver. It can be set anywhere from 40 to 140 Hz. For instance, if the filter is set at 75 Hz, only frequencies 75 Hz or below will be delivered by the subwoofer. This allows the sub's output to be matched to the lowest reproducible frequency of other speakers in the system and the room's acoustics for a seamless presentation.The rotary volume control permits the perfect matching of the sub's output to the overall volume of the system. The YST-SW315 has a signal-sensing circuit. When the subwoofer detects an audio signal, it turns its power on. When it senses no signal for several minutes, it shuts itself off.Yamaha's BASS (Bass Action Selector Switch) tailors the sub's output for video or music at the touch of a switch. Two sets of inputs let the sub accept either line- or speaker-level inputs, while a handy phase normal/reverse switch makes it easy to phase the subwoofer with the other speakers in your system.Three-way speaker terminals accept banana plug and a variety of other connectors, as well as speaker wire, and the YST-SW315's thick, rigid MDF cabinet reduces vibrations and resonance. The speaker's handsome black-ash finish blends in with room decor and complements many furnishing styles, and it's magnetically shielded so you can place it near a TV or computer monitor without degrading the picture.What's in the Box Subwoofer, user's manual, and warranty information.

this is exactly what all the previous reviews said it was......a truly deep value for money. the bass is as deep as could be without noticeable distortion and it is clean looking enough to pass the wife's scrutiny. i am a music buff and i find the bass production to be just as good as the very, very good sony sf 6000 front speakers i use. however the big advantage with this unit is when watching movies.....5.1, 3.1 or 2.1, the bass is way deeper than you can get with the big front speakers. the difference is really dramatic, even to a new comer's ears.
it should be also noted that the unit DOES have an auto off function (not described on Amazon) which can be disabled at the back. this is great, except when actually watching a movie because it shuts of within 5 mins if it does not receive a low bass signal from the amps, so during dialogue it sleeps in low power and then has a delayed restart when the bass returns.
i use my sub in a large room and you really have to crank the power up, close to max, to be truly impressed. so i think maybe the bigger rooms need the bigger 15" sub, but i have not compared it to be sure but it is worrisome to operate so close to max, even if it is sweet to the ears. if you have a medium or smaller room you should be overwhelmed.
anyway, i am certain that you cannot find a sub with similar specs and great reviews anywhere near this price so i urge you........ENJOY!!!

Energy ESW-M6 800 Watt Mini Subwoofer (Black) Review

Energy ESW-M6 800 Watt Mini Subwoofer (Black)
Average Reviews:

(More customer reviews)
I took delivery of this subwoofer yesterday and hooked it up immediately to my "second" system, which consists of an Oppo BDP-80 universal player, Onkyo TX-NR807 receiver, and a pair of Dynaudio Focus 110 monitors. The Dynaudios are small but capable of room-filling sound with decent bass extension; I had been running this setup without a sub, and it was more than adequate for casual listening and video viewing.
When you take the ESW-M6 out of the box, its size is disconcerting -- it's just 8" on a side, with three sides totally consumed by the 6" woofers (one active front-firing, two passive side radiators). You're thinking, "this might work for desktop audio, but it will never make enough sound to fill my living room, and no way will it match my Dynaudios for musicality."
Wrong and wrong again. After I set a couple of knobs and switches on the back and connected it to the receiver, I ran Audyssey MultEQ with the new speaker in the mix. Had to go back and set crossover manually, however, because Audyssey had set it at 40 Hz, way too low to give this little cube any work to do (it bottoms out at 42 Hz, according to the manual). So I tried a crossover at 80 Hz, quite nice, and at 100 Hz, even better.
Bottom line, this sub really delivers. I used two jazz CDs with good clean acoustic bass lines to listen carefully before-and-after for pitch (i.e., can you hear the note and not just a thump?) and lower distortion. The Energy sub scored high on both counts. This was not subtle! The bass line was consistently easier to follow; adding in the sub took some pressure off the Dynaudios, so they produced cleaner sound above 100 Hz, and the Energy ESW-M6 easily handled the material below the crossover point.
A bonus was that the bass now sounded more substantial. There was a very pleasant, appropriate sense of fullness to the bass sound that had been missing before. I'm not saying that those 6" speakers managed to fully pressurize my semi-large, high-ceiling living room. But they delivered a realistic, musical, "woody" bass-fiddle sound that the Dynaudios had not pulled off. And they didn't strain and distort anything in the process.
When the M6 is broken in, I'll try out more demanding material -- symphonic music and movie special effects -- and return to this review with the results. But for now, I'm really pleased. The 200-watts-RMS amp (ignore the 800 or 1200 watts "dynamic" rating) is obviously effective in powering this well-designed unit. Apparently size no longer matters! The performance of the Energy ESW-M6 far exceeded my expectations.
(OK, back with an update. Ran the lobby shootout sequence and a few other moments from "The Matrix." Sub performed very well. Did NOT best the $15K multichannel setup in my 15x19x8 home theatre, which still sounds more spacious and impactful. No surprise there. It was very interesting to note, however, that the electric bass line in the shootout often sounded cleaner and more rhythmic on the little Energy sub! Less thump, more music. I also had a wonderful time with Bach: Violin Concertos -- the cellos and basses sounding astonishingly big.)
Strongly recommended, especially for those who don't want to see a big ugly sub in a living area (the piano black finish is quite elegant, although it shows fingerprints easily). Incidentally, the backside controls include a variable low-pass filter, a zero-to-360-degree phase control, a selectable auto-on feature, and two line inputs. This is what you would expect for a sub in this price range, and it's another sign that this is no toy. It is NOT to be confused with Energy's home-theater-in-a-box products, or with computer add-ons. Rather, it's competitive with Velodyne or REL products in this price range.

The sub itself has a nice sound quality at low levels. When you try to really crank it up it is not as loud as I would have liked. A little distorton creeps in at high volume levels. As a compliment to a large system with a few woofers that dont play low frequencys very well it does an excellent job. But as a stand alone woofer I think some would be a bit dissapointed. The other complaint that I have is that the grill likes to really rattle and buzz around 120 hertz.I do like the volume control and the x-over controls. Set the x-over control at 100 Hertz or lower depending on what other speakers you are using with this unit, Keep the volume around half throttle and enjoy.

Sony SA-W2500 Performance Line 100 Watt Subwoofer Review

Average Reviews:

If you're thinking about buying a subwoofer, it is unlikely that you are a garden variety movie fan or lover of music. People looking for subwoofers usually already have a decent system, but know that there is something lacking.
When it came for me to buy one, three factors weighed in my decision: power, brand, and (of course) price. I've grown up with what I have always believed to be a 'healthy skepticism' when it comes to Sony products. My father had an early generation (1990ish) 5.0 Sony 250 Watt surround amp that performed extremely poorly in just about every function. The only advantage it had over his earlier (1978) Rotel non-tube amp is that it had multiple component inputs. The sound quality of the 50 Watt rated Rotel amp blew the Sony out of the water.
In my search for a subwoofer, I was surprised to find so many good reviews of the Sony line. I was looking for a better name than Sony, but when I compared prices, I was compelled to give the Sony at least a listen. Comparable subs by Velodyne and others were far more expensive (double the cost of the Sony or more). Listening to the Sony at the stereo shop, I must say that I was extremely impressed.
Is the Sony sound as good as the Velodyne or other high end subwoofers that cost 2-3 times as much as the Sony? Of course not, but I quickly discovered that difference in sound quality was not at all closely related to the difference in price.
Keep in mind that this is one of Sony's smallest and lightest subs (only 25 lbs), but once I brought it home and hooked it up to my 6.1 surround system and configured the frequency and volume on the back of the sub, it seamlessly expanded the low end range of my system for music and movie playback. Before I learned (by experimenting with them) how to adjust the levels on the back of the sub, it was quite boomy and there was a bit of a gap between the low end on the six surround speakers and where the sub picked up. When I made the appropriate adjustments, by trial and error, I found that this sub is an extremely versatile fit for my home. My family room is 17'x14', and the back opens into a 10'x15' living room, and the sub easily fills the room. When I crank the system for rock and roll music and movies, the sub has no problem keeping up and is easily capable of playing more loudly than is safe or enjoyable.
Would I have liked a bigger sub made by a better brand? Sure, but this one does the job (and then some) admirably, and for less than half the cost. This sub gets 4 stars as a product, but I gave it 5 because of the extremely good value. If you have a big budget and can afford to spend what it would take to buy a speaker that actually sounds better than one of these Sony subs, go for it, you will not be disappointed. On the other hand, if you would rather spend less on a sub and still get excellent power and sound quality, this is as good as it gets without spending several hundred dollars.

Yamaha YHT-150 600-Watt 5.1-Channel Home Theater in a Box (Silver) Review

Yamaha YHT-150 600-Watt 5.1-Channel Home Theater in a Box (Silver)
Average Reviews:

(More customer reviews)
We wanted an HTB (Home Theater in a Box) for less than $300 for our Master Bedroom, to go with the new small HDTV. We already had the other components (DVD, etc.), so we wanted an HTB without the DVD but with plenty of component connections for future expansion. After some shopping we purchased the Yamaha YHT-150.
However after purchasing this product, I struggled for 2 weeks to like it, but in the end I finally did. I debated about taking it back and I looked at several other systems during these 2 weeks, but really couldn't find anything better in this price range.
Both the receiver and the powered subwoofer are excellent, but my 2 week struggle was with the other 5 speakers (NS-AP-1500s).
After setting the system up, I tried the DVD movie "Twister" (always a good HTB test movie), but the sound was "flat", "hollow", somewhat "tinny" and low volume (IOW, had to turn the volume way up). The speaker sound reminded me of being at the drive-in theater (remember what those speakers sounded like). This is when I entered my 2 week struggle with the system.
To start sorting it out, I tested 2 of the speakers on another system, and quickly discovered that they are not very efficient (it takes power to get sound out of them), but I also discovered that the sound they produced was very clear and clean, unlike the YHT-150.
So back to the YHT-150, I realized that the speaker wire that came with the system was only 22 gauge wire (though it looks heavier) which I used to set it up. So I theorized that this wire was too small for the power required to drive these speakers, and that this might be responsible for the unwanted sound effects. So I bought $5 worth of cheap 16 gauge speaker wire at Home Depot for a test, and rewired the front 3 speakers. Then I turned on the local classical FM station, and WOW, what a world of difference the 16 gauge wire made! I could hear richness and detail in the piano solo, and even people quietly moving around in the background of the recording.
However at the new more powerful and cleaner sound levels, I could now hear that the speakers had no low-end bass (which is noted in the manual specs), but the subwoofer was not filling in the bass correctly to compensate for this. There would be a sound from the speakers (like a voice for example) that should have a bass component, but only a rumble from the subwoofer. This problem turned out to be the cheap subwoofer cable that came with the system.
So I ordered a 100ft roll of good quality 16 gauge speaker wire and a good quality subwoofer cable, both for $38 total (I caught both on sale), and both of these have transformed the system. The speakers now deliver good clean clear sound at significantly reduced volume settings. The required volume settings are still higher than I'd like due to the speaker inefficiency, but the receiver has more than enough power to drive them in a bedroom setting, so this is not an issue. The excellent subwoofer is now very clean and tight, and it accurately fills in the bass for sounds that have bass.
In the end, I've come to like this system, and it does a really good job for the reasons we bought it. I'm not sure I'd recommend it for a large living room as I don't think it has the power to fill a large room, but it can fill a bedroom or a smaller living room just fine.
I have a couple of other issues with the sytem. First, the remote looks a little cheap, but it works fine. Second, the system was a little complicated to figure out and setup, and I think this system needs to be setup correctly for it to deliver its excellent sound potential.
All in all this is a nice system, and I recommend it.

Hunting for exciting, dynamic surround sound on a budget? You've landed at the right system. It's no mirage: Yamaha's affordable YHT-150 includes the 5-piece NS-AP1500 speaker ensemble, a YST-SW010 subwoofer, and Yamaha's HTR-5730 home theater receiver, which pumps 100 watts per channel x 6 discrete channels (at 1 kHz) and offers a host of options for rendering the type of surround sound best suited to your taste or programming.The powerful HTR-5730 receiver accepts the DVD player's Dolby Digital, Dolby Pro Logic II, and DTS 5.1-channel surround signals and routes each channel to its designated speaker. Additionally, the receiver's Silent Cinema and Night Listening modes enhance headphone and low-level listening, respectively, while Yamaha's 32-bit Cinema-DSP processing gives you an additional 24 surround effects to enhance your movies and music. With the HTR-5730's 5.1-channel analog inputs, you're ready for high-resolution DVD-Audio/SACD playback, too, whether from your current disc player(s) or from any future devices to which you might upgrade. The receiver offers a total of 4 AV inputs, and its tuner section offers 40-station AM/FM preset tuning.The 6-speaker complement includes the 5-speaker NS-AP1500 for the front, center, and surround speakers and Yamaha's YST-SW010 subwoofer for deep bass, which is important for effective home theater sound. Each speaker in the NS-AP1500 ensemble uses a sealed, acoustic-suspension design with dual 2.5-inch pulp-cone woofers. The center speaker is specially configured for TV placement and--as it handles upwards of 70 percent of a movie's audio, including most voices--it's engineered for slightly more full-bodied sound than the other speakers.The 100-watt, 6.5-inch subwoofer uses a spruce-cone driver and Yamaha's patented Advanced Active Servo Technology (Advanced YST), generating incredible bass from its small enclosure. Advanced YST uses negative-impedance feedback in the amp and a Helmholtz resonator in the speaker to provide strong and accurate bass.QD-Bass (Quatre Dispersion Bass) technology uses a down-firing driver with square, pyramid-shaped reflective plates to radiate sound with equal effectiveness in all directions. The sub's individual volume control permits the perfect matching of the sub's output to the overall volume of the system. The sub has a signal-sensing circuit, too. When it detects an audio signal, it powers right up. When it senses no signal for several minutes, it shuts itself off.All speakers included with the YHT-150 feature magnetic shielding, so they can be placed near a TV or monitor and cause no picture degradation.What's in the Box Surround amplifier, 5 speakers, a powered subwoofer, a remote control, remote batteries, a user's manual, all requisite cabling.
