Yamaha YST-SW315: Uncompromising subwoofer

Even budget Yamaha audio equipment always looks thoroughbred. This subwoofer is no exception, which stands out with its excellent lacquer finish and convenient control interface (the control panel is located on the front wall). But the main advantages of the YST-SW315 are inside. Under the 25-centimeter bass driver, installed in the bottom part, there is an acoustic reflector that distributes sound pressure in four directions (Quatre Dispersion design).

The amplification circuit uses special Advanced Yamaha Servo Technology feedback, which, by tracking the position of the diffuser, causes the emitter to oscillate in exact accordance with the electrical signal arriving at the sub. The standard adjustments are supplemented by two operating modes – with the BASS button you can change the frequency response characteristics. One position is for music playback, the other for deep bass cinematic effects.

In its price range, the YST-SW315 deserves the title of an uncompromising subwoofer. The device has stunning dynamics both at the beginning of the low-frequency range and in the high bass. Vibrating resonances are minimal. Box overtones are also well muffled – only on clear low sinuses can you sometimes notice the hoarse “exhalation” of the bass reflex (it’s strange that it exists at all – the port has a large diameter and a regular rounded bell). Excellent results from a Yamaha sub can be achieved with both low and high filtering settings.

The YST-SW315 subwoofer delivers exceptional bass performance for a truly enjoyable music and movie experience. It uses two proven technologies – Advanced YST and QD-Bass, providing deep and powerful bass with amazing clarity. The BASS (Bass Action Selector System) switch allows you to select between music and movie soundtracks, and you can also set the low-pass filter cutoff frequency, allowing you to achieve the optimal frequency response for each audio source. This ultimate, powerful subwoofer can greatly improve the sound quality of any system.
