True to their 'sound first' philosophy, the Cambridge Audio SX120 subwoofer brings quality to the deepest notes.

Deep, effortless bass
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 now delivers the type of bass you'd usually expect from the largest and most powerful floorstanding speakers.

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

Flexible placement
Letting you 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 SX120 makes a big impact on your listening enjoyment.

Rated 5 out of 5 by from Great bass This subwoofer really enhances my triangle AIO s and the sound is quite remarkable

Rated 5 out of 5 by from Best honest advice from the experts I bought a Cambridge Audio Subwoofer this month. Seamless ordering with some advice on connection and cabling. Mind at rest that I was buying the right speaker for my set up.

Rated 5 out of 5 by from Great addition to my Hi-fi This is the first time I have used a sub in an audio context, and I was concerned that it would be too explosive for the predominantly acoustic music that I use it for. With this in mind, I was drawn to Cambridge Audio, as their AXR100D receiver provides the smooth natural sound that I need. The SX120 complements it beautifully, just opening up greater breadth and depth to the sound, without ever seeming intrusive, or working against my vintage B&W speakers. The service from Richer Sounds was impeccable, as ever. Felix at the telesales team took me smoothly through the process of returning an item and making this purchase, which arrived promptly and safely.

Rated 5 out of 5 by from Brings my systems alive! I had an SX120 with my vintage Yamaha amp and NS10 speakers and new streamer. It really has some depth now so having seen the great price for such a good sub I have now added a second one to my Cambridge Topaz amp and cd with SX50 speakers for my study. It too has lifted a basic system to a high quality system equivalent at much higher costs. A great service too. It arrived the day after my on line order!

Rated 4 out of 5 by from Compliments Cambridge SX-60 speakers I've two Cambridge SX-60 speakers and bought this SX-120 sub to compliment them, I'm no audiophile but they sound excellent to me driven with my new Bluesound Powernode. I was planning on getting the CXN V2 but my Cambridge Amp packed in after less than 2 weeks of use, I'd purchased it for my new house, however when the purchase fell through it sat in it's box until I found another "affordable" house in Cambridge, by which time the warranty had well expired, which was my fault.

Rated 5 out of 5 by from Incredible bass that adds depth and richness The SX120 speaker has a deep, rich bass that really adds depth to the overall sound of my music. It's a game-changer for my home theatre setup!

Rated 5 out of 5 by from Lovely engineering and a great sound. I have been using the subwoofer for the past week and I love the sound it makes. In contrast to some others on the market, it is good to have some controls for a personal adjustment. I’m not too sure about the Sharp points on the feet. Not too good on my wood floor! Some extra pads to prevent scratching would be nice. Are there than that, I’m very pleased. And a good price too.
