Add bass to your home entertainment experience with the Sony SA-CS9 115W 10-Inch Active Subwoofer. Its 10-inch woofer is powered by a 115W amplifier. With a frequency response of 28 to 200 Hz, the SA-CS9 is equipped to handle a wide variety of listening material. Its controls include a phase switch, level adjustment, cut-off frequency adjust, and a power save mode. For installation flexibility, speaker and line level inputs are onboard. The woofer includes a 6.5-feet phono cord and four foot pads.

Active Subwoofer for Thumping Bass

Enjoy deep, rich bass from this powerful active subwoofer. The 9.84-inch cone diaphragm can move a larger volume of air, producing powerful low-end resonance that makes bass sound rich and authentic. The subwoofer reinforces low frequency sounds in movies and music for a great multi-channel home theater experience.

Mica-Reinforced Drivers 

CS Series speakers utilize unique, foamed (dual-layer) mica woofer diaphragms-the upper surface delivers supple and faithful sound quality, while the bottom layer leverages low weight with great strength for powerful bass response. 

Built-In Amplifier

Drive bass-heavy music and bring your party alive. This subwoofer includes a built-in amplifier with up to 115W power output. Electrical circuits susceptible to vibration are located outside the cabinet, releasing high pressure within the enclosure for a clear and powerful bass sound.

Minimizing Vibration for Tight Bass

Suppressing vibration in the cabinet is vital for tight, accurate bass. Unwanted vibrations are handled in two ways: by acoustically absorbing waves generated from the rear pressure of the unit, and damping vibrations within the cabinet itself. Designers optimized the type and layout of sound absorbing materials to keep cabinet vibration to a minimum.

Bass Reflex System

The subwoofer is built on strong foundations with an enclosed structure designed to keep sound pure and natural. Bass reflex ducts suppress unwanted noise and improve low frequency sound reproduction so you hear deep, powerful bass from music and movies.
