Cambridge Audio SX120 (Black)

Subwoofer

In stock
£179
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 4 out of 5 by from Good value for money. Purchased to replace a KEF HTB2 subwoofer which had given up the ghost. Good sound, although perhaps not quite as thundery (and certainly not as sexy looking!), but for the money does the job well. Another quality Cambridge Audio product.

Rated 5 out of 5 by from Add great base to my surround sound amp Brought this 3 weeks a go didn’t quite know which subwoofer to go for was recommend this one by James in your Eton shop very pleased with it all though it’s only 75 watts it packs a great rumble to action films not tried it with music yet . The auto off feature is great no more remembering to turn sub off .

Rated 5 out of 5 by from Clear bass, great addition I bought this sub-woofer to go with a Denon M-41 amp and Cambridge Audio SX60 speakers that are wall mounted. The richness and definition of sound has been improved dramatically (it was already pretty fine!). Service and delivery are second to none, thanks Richer Sounds!

Rated 5 out of 5 by from Brings out the bass I have a Cambridge Audio CXA60 paired with AE 301 shelf speakers. There are moments when I feel that more bass would add that extra sound dimension waves crashing, thunderstorms, 70`s rock music and I can`t accommodate larger floor speaker with my room set up. This powerful sub-woofer does the job brilliantly and gives mt the all round sound that I was missing. And it was on sale a bargain!

Rated 5 out of 5 by from Great Sound, Superb Value I had been looking for a sub to complete my home set-up, a Denon AVRX Receiver, a couple of Mission Bronze stand-mounted speakers and a matching centre speaker. I liked the sound but I just felt the bass was lacking a little - not any more its not. For £150 this sub us incredible, it takes a little bit of trial and error to get the levels matched but once done, the transformation of the overall sound is amazing. Even at low volumes, the bass is clear and rumbles across the floor, at higher volumes it lifts the entire sound and even allows the other speakers to perform better by taking the bass job away from them. I am delighted, this is a brilliant piece of kit for the price.

Rated 5 out of 5 by from Great piece of equipment I have a full sound system and recently my subwoofer broke so I purchased this item and I’m thankful of it the sound and bass off it is extremely satisfying. I most certainly would recommend this to anyone

Rated 5 out of 5 by from Lots of 'bang for your buck'. Extremely pleased with this sub, it has a very smooth delivery without feeling too lazy but also nice and punchy when watching action films etc. Build quality very good as you'd expect from Cambridge Audio & great service from Richer Sounds
