Yamaha 250 Watt Powered Subwoofer-Piano Black

Yamaha's Advanced Active Servo Technology is a complementary amplifier/speaker system utilizing negative impedance feedback in the amp and a Helmholtz resonator in the speaker to provide strong and accurate bass.

Bass Selector

• Yamaha's BASS (Bass Action Selector Switch) tailors the sub's output for video or music at the touch of a switch

Yamaha QD-Bass Technology

• A Yamaha technology that uses a down firing driver to radiate the bass output more efficiently. Sound is radiated in all directions for greater impact

Continously Variable High-Cut Filter

• 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 other speakers in the system and the room's acoustics for a seamless presentation

Volume Control

• The volume control permits the perfect matching of the sub's output to the overall volume of the system

Dual Inputs

• Two sets of inputs allow the versatile subwoofer to accept either line level or speaker level input signals
