Our take on the Cambridge Audio SX-120 by Crutchfield's Dave Bar
Give your sound system a deep foundation
The SX-120 may be compact, but it can certainly pack a punch when needed. A built-in 70-watt amplifier helps it deliver some serious low bass performance all the way down to 34Hz. It's a perfect match for Cambridge's SX Series speaker line, and works great when used in a stereo music setup or home theater system along with the SX-50 or SX-60 bookshelf speakers.
Designed and engineered with passion
All of Cambridge Audio's SX Series speakers are carefully designed and tested at their London facility by a team of engineers fueled by their passion for incredible sound. The SX-120 uses an 8" forward-firing woofer and dual rear ports to create full-bodied, dynamic bass for all your favorite music, movies, and video games. The rigid cabinet comes with spiked feet to help keep the bass tight and well-controlled. It means you'll hear clean, detailed lows, even when you crank up the volume.

8" Long-Throw Woofer: The Cambridge Audio SX-120 powered sub employs a custom designed 8" long-throw woofer with treated paper cone for a smooth and even frequency response.
70W Amplifier: The SX-120 powered sub use a 70W (RMS) amplifier for dynamic bass response.
Rigid Bass Reflex Enclosure: The Cambridge Audio powered sub features a rigid MDF cabinet, expert designed to minimize standing waves and deliver deeper, tighter bass response. The enclosure features two rear-firing ports for improved efficiency and bigger bass output.
RCA/LFE Input: The powered sub has gold plated left & right RCA line-level inputs for use with receivers having a subwoofer or stereo preamp output that do not contain their own low-pass crossover. The left channel RCA input doubles as the LFE input, if your receiver has an LFE output and a built-in low-pass crossover.
Controls: The Cambridge Audio SX-120 features individual controls to tailor volume, crossover frequency. and phase adjustment.
- Volume Control: The SX-120 powered subwoofer has a rear-panel rotary volume control to adjust the volume of the subwoofer relative to the other speakers in the system.
- Crossover Frequency: The SX-120 offers a continuously variable low-pass filter, adjustable from 50-150 Hz.
- Phase Adjustment: The subwoofer's phase adjustment allows you to adjust the subwoofer's phase between 0° or 180°. If the bass sounds muddy or unclear, adjusting the phase control can sometimes strengthen the bass performance.
Auto On/Off: The SX-120's Auto On/Off feature will switch the powered subwoofer On and Off automatically by signal detection. The powered sub will enter "standby" mode when there has been signal activity for 30 minutes or more.
Applications: The SX-120 is ideally suited to complement Cambridge Audio's SX series speaker line-up and other brands of speakers, adding deep and rich bass extension to your movies and music soundtracks.
Placement Options: The powered subwoofer can be placed almost anywhere in the room as bass sound is largely non-directional. For best results, place the subwoofer on the same side of the room as your front speakers. Corner placement will increase the powered subwoofer's output.
Spiked Feet: The Cambridge Audio SX-120 powered subwoofer includes four spiked feet for added stability on your carpeted floors. The spiked feet are adjustable, in case you have uneven floors. The spiked feet add 1.25" to the height of the powered sub. The powered subwoofer can be used with or without the four spiked feet, in case you have tile or hardwood floors.
