Amazon.com Product Description
Round out your home theater system with the high-performance Yamaha YST-SW225 120-watt subwoofer. Boasting an 8-inch multi-range driver and Yamaha's QD-Bass and Advanced YST II technologies, the subwoofer adds a deep, powerful bass response to your favorite movies and music. QD-Bass technology employs down-firing drivers and square, pyramid-shaped reflective plates to radiate the sound efficiently in four horizontal directions, ensuring dynamic power and a smooth frequency response regardless of the subwoofer's location. Advanced YST II technology, meanwhile, optimizes the speaker impedance to create more stable, energetic, and accurate low-range tones.
Adding to the audio quality is the luxurious magnetically shielded wood-finished cabinet, along with the highly efficient internal amplifier that consumes little power while still producing a big sound. As a result, the speaker creates a clear, spacious sound stage that evokes the high-end audio at commercial movie theaters. The YST-SW225 produces a generous overall frequency response of 28 to 200 Hz, which dovetails nicely with the specs of Yamaha's complementary 225 PMD home theater speaker series, which includes floor-standing tower models, rear bookshelf units, and a center channel speaker.
Additional features include a linear port that minimizes extraneous noise and distortion, a Bass Action Selector System (BASS) that lets you switch between movie and music modes to enjoy an optimum frequency response for each, and a low-power standby mode that consumes only 0.5 watts of power. The subwoofer measures 11.44 by 13.88 by 13.75 (W x H x D) and carries a two-year warranty on parts and labor.

Product Description:
Yamaha's patented Advanced Active Servo Technology (Advanced YST II) generates incredible bass from small speaker enclosures. Its advanced negative impedance converters intelligently adjust the negative impedance generation as the speaker moves, creating a hard, rigid cone that prevents deep resonant waves from leaking out of the speaker cone. This means the full power of the waves is forced out through the air port, resulting in clear, powerful bass. The user-adjustable continuously variable high-cut filter sets the highest frequency the subwoofer will deliver. It can be set anywhere from 50 to 150 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 other speakers in the system and the room's acoustics for a seamless presentation. Auto Standby Power On/Off with Override Switch Line Level and Speaker Level Connections
