The Yamaha 8″ 100W packs a powerful punch with YST technology and the Twisted Flare port. Its resonant and deep bass enhances your listening experience, regardless of the audio source.

Due to its 11-1/2″ x 11-1/2″ x 13-3/8″ dimensions, the subwoofer is compact enough for small rooms. Since it doesn’t take up a lot of space, you can couple it with speakers and other equipment.

But don’t be fooled by its small size. The Yamaha subwoofer has a 100W amplifier and an 8″ cone driver that offers great sound quality. These features make it perfect for music and movies, so you can enjoy all your favorite tunes in any room.

The driver’s capabilities are matched by YST II, Yamaha’s Active Servo Technology II, which uses a negative-impedance amplifier to ensure synchronization between the input signal and the cone driver. That results in accurate and distortion-free bass at high volumes too.

What makes this Yamaha subwoofer better than its competitors is its ease of use. The intuitive control panel lets you adjust phase, frequency, and volume per your preferences. Plus, the auto standby function turns off the subwoofer when not in use and turns it back on when it receives an input signal. The standby mode helps save energy and lower your power bills.
