I would recommend a different subwoofer for high end home theaters. Bass bottoms out at about 25Hz.





Buy one!! You won't be let down!!
UPDATE!!!!!!!
I will be picking up a second one of these very soon!! The first one is still alive and kicking and I need a second to go with it for even more bass!!! Amazing product!!







I have relocated it several times to different rooms to accommodate the occasional Halo death match with my friends, and it never ceases to amaze me.
It's got a nice wooden feel (not sure if it's real wood or plywood), with a nice polished black finish. it just says "classy" when you look at it. Best of all, it has a sleep function so you don't have to turn it on or off - after you shut everything else down it powers off on it's own. When you turn everything else on, it clicks on by itself.
6 years of using this thing, and I have zero regrets.

Without hesitation I recommend this subwoofer to anybody considering a robust and high quality subwoofer at a very reasonable price.


I purchased the YST-SW315 for my home office, to provide extra depth for the surround system that I have connected to my computer and other A/V equipment. The SW315 subwoofer sits on the floor, hidden below a corner desk unit. This sub enclosure measures 13-3/4" (W) x 16-15/16" (H) x 15-1/16" (D), and weighs roughly 42 lbs. Although it's not extremely small, this sub really doesn't take up that much room. It is a fairly square shaped box with a flat surface, so you can always sit something on top of it if you desire. I have the sub hooked to my surround receiver via the line level inputs. However, there are also speaker level inputs and outputs, for those that wish to connect the subwoofer inline, between their stereo amplifier and stereo speakers. It is magnetically shielded, so this subwoofer can be placed next to anything without worry of magnetic interference from the speaker itself.
The YST-SW315 subwoofer utilizes two technologies that are unique to Yamaha.
* Advanced YST - Advanced Yamaha Active Servo Technology is a unique system in which the speaker and amplifier work together to cancel out impedance so the speaker unit has a perfectly linear motion. Advanced YST helps to ensure the highest levels of sound pressure and overall performance.
* QD-Bass Technology - Quatre Dispersion Bass technology uses down-firing drivers with square, pyramid-shaped reflective plates to radiate the sound efficiently in four horizontal directions. The reflective plates negate any effects caused by the floor surface and reduce resonance between sound waves reflected from the floor and the unit.
I don't know much about Advanced YST and QD-Bass Technology, but I do know this subwoofer sounds great. Although relatively small, this little speaker box packs quite a punch, and fills the room with deep sound that you can feel as well as hear. I use this subwoofer for a combination of listening to music, for computer game play and for watching movies. There is a button, on the subwoofer control panel, that lets you select "Movie" or "Music" mode. There is a noticeable sound difference between the two modes, so a user would definitely want to utilize this button when switching between watching movies and listening to music. The control panel, which is located on the front side of the subwoofer cube, also contains a volume knob, an auto standby (on/off) switch, a high cut filter (on/off) switch, and a high cut filter adjustment knob. The auto standby feature is very handy, as it allows the subwoofer to power itself up when it receives sound and goes into standby (sleep) mode when no sound is present after about 5 minutes. Power consumption, while in standby mode, is only 0.5 watts, so I personally love the convenience and energy efficiency of the auto standby feature. If you prefer to power the subwoofer on and off manually, the main power switch is located on the back of the unit, rather than on the control panel itself. Next to the on/off power switch is also a Phase Control switch, so you can select whether you want the sub to work in normal or reverse phase. I will not go into what phase changing does to the sound, but audiophiles will understand that reversing the phase would be the same as reversing the positive and negative wire connections on the back of a loudspeaker. It simply changes whether the speaker cone moves inward or outward to produce sound waves.
The high cut filter adjustment control works very well, allowing you to determine the high-end frequency cutoff of the speaker. Obviously a subwoofer is meant to produce very low frequency sounds, so being able to cut out somewhat higher frequencies can produce much cleaner, punchier bass sound. This control allows you to customize the bass sound, to best match the speakers that you have producing the higher frequencies. When set correctly you should experience a full bodied sound, without any dropouts in the frequency range between the main speakers and the subwoofer.
Here are some technical specs of the YST-SW315:
* Advanced YST Technology
* QD Bass Technology
* High Efficiency Power Amplifier: 250-watts nominal / 270-watts dynamic power
* Multi-Range Driver: 10" Cone
* Magnetic Shielding
* Phase Control Switch: Normal or Reverse
* High Cut Filter: 40 - 140 Hz
* Auto Standby
* Bass Action Selector System: Movie Mode or Music Mode
* Inputs: Line-level in (RCA phono x 2), Speaker-level in (heavy-duty post x 2)
* Outputs: Speaker

the only downside is the little stick-on rubber feet. they shouldve made the 4 corners threaded, with screw in feet. I just know that once i move these stickons wont last.
Yamaha did it again! Another great speaker product!


I did have the Yamaha in mind when i bought the Polk and was going to buy it instead. I went back and forth on the two and gambled wrong. I sold the Polk and Bought the Yamaha and i couldnt be more happy! The Yamaha was the missing link in my system.
The sound was really different from that of the Polk. It wasnt boomy and didnt fall behind on any note that i through at it. The sound seemed to blend in and if you closed your eyes you could not pin point the Yamaha.The sound just seems to come from everywhere as it should. I also noticed on Blueray soundtracks it even seemed to play lower and just as loud as the Polk.
Bottom line is in my opinion the Yamaha stands on top and in the price range it can be beat in sound quality. So if you are have second thoughs on this subwoofer dont!! Just click the by-now button get it opend,set it up and enjoy.
