Richer Sounds exclusive model.

Gimmick-free and true to their 'sound first' philosophy, the Cambridge Audio SX120 takes sound to a lower dimension.


Powerful sound, right down to 34Hz

At the heart of this Cambridge Audio subwoofer you'll find an 8", long throw woofer, powered by a high quality 70W amplifier. This combination gives effortlessly deep bass that transforms music and movie soundtracks. With a response down to 34Hz, your system will now give the type of bass you'd usually expect from the largest and most powerful floorstanding speakers.

Power with control
Unlike lesser designs, the SX-120 marries this force of power with tight control. Painstaking port design and a rigid MDF cabinet ensure distortion has been kept to a minimum. The amplifier and cone design have also been optimised for tight, punchy control just as much as ultimate bass depth.

Flexible placement
Allowing you to tailor the SX120's sound to your room, system and personal taste, the SX120 comes with variable volume and frequency response controls. There's also phase control that facilitates the positioning of the subwoofer behind your listening position. Finally, an auto power switch allows you to power the subwoofer off/on via your receiver or amp, meaning it can be tucked out of sight.

The perfect match for the SX50 or SX60 speakers but also ideal with many other speakers, the Cambridge Audio SX-120 makes a big impact on your listening enjoyment!

Rated 5 out of 5 by from Great sub at a good price. This sub was a bargain. Bought it to replace my 15 year old sub, one that I thought was great. That was until I set this one up, if you are after a great sub at a really good price this is the one. The bass is really deep and clear without being over bearing.

Rated 5 out of 5 by from Very powerful. Recently bought this to add to my relatively small av system. I really cant use it above a quarter power or it makes the walls shake but it's beautifully clear and defined. Great for action movies and if tweaked down a little more adds real depth to my music. Definitely recommend.

Rated 5 out of 5 by from Does the job I wanted to add a small sub with auto on off to my mini hifi, I was going to buy the Yamaha priced at the time £109, in the info it said it had auto on off...it doesn't So I was advised on this one, easy to set up and adds that oomph in my smallish living room. The feet though....if anyone has a wooden floor they might want to put some protection down

Rated 5 out of 5 by from Excellent sound quality! Bought this just after Christmas to enhance our surround sound system. Had a subwoofer many years ago, but it was way too boomy, so I was a little apprehensive about buying another. I read all of the positive reviews on here and decided to give it a go. Wow! After using the auto calibration on my Sony STR-DN 1050 receiver, what a difference this has made, it's totally lifted the sound of all of the other speakers and transformed what was a quite full sounding system into a whole new cinematic experience. Time to get all of the Blu-ray's out again and experience all our back catalogue of films again in full cinematic surround sound. Great price and great service from Richer Sounds. I would definitely recommend this subwoofer, can't be beat at this price £149!

Rated 5 out of 5 by from Great budget subwoofer I completed my entry set (AT-LP120, Q accoustics 3020, Onkyo A9110) with this one and I have to say the sound is more complete now. Setup is really easy with only difficulty setting the crossover frequency (there are however lots of online guides). Music has more depth, getting closer to what the artist intended to create. Movies can create a good cinema atmosphere, feeling the shake when increasing the volume

Rated 5 out of 5 by from Does the job Compliments my Onkyo-TX8250 and Tannoy Mercury V4 floor-standers very nicely indeed. My first sub-woofer. Love it.
