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.

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.
I looked around a long time for the right sub, and, I like to think I got a good one here.
You want power? Ok, it's only 250 watts -not 1,000 watts like Velodyne, but in my room (30 by 18ish with a 25 foot ceiling) it ROCKS.
I love music, all kinds; loud or quiet no matter I like both, but I do like depth more than volume. However, I believe if you are going to listen to something real loud, being able to feel the music is as important as being able to here it.
And let me say you can FEEL music if you want to.
one of the things I love most about this sub is it's range; it can (maybe) reach 20 hertz. 20 hertz! that is astounding.
20Hz is the lowest frequency the human ear can hear, in fact it's starting into the range of sounds that are felt more than heard.
Maybe I have good ears and maybe I don't, but to hear rich airy low-end, and, bass notes. yes! bass NOTES! bass is not one big boomy lump of noise, it's huge, open, grazing pasture of distinct sounds!
In short, music sounds great, even hip-hop (which I don't like) sounds, well, better.
Also, their is no need to turn the volume way up to hear a improvement; at very quiet levels too, you can hear good clean bass notes. But, if you do a lot of quite listening, we're talking back ground music levels: disable the auto-on feature and manually turn it on and off, because if you happen to be listening to something quiet, even if you still can here low notes from this, it does not seem to be enough signal to keep the auto-on, well... on.Read more ›
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.Read more ›
