Tech Specs

Even though it handles a smaller part of the overall frequency response than any other speaker, a subwoofer requires careful design and engineering. It has to deliver deep, powerful bass that is fast and well defined enough to integrate seamlessly with your other speakers. The SX120 subwoofer was designed from the ground up by our engineers in London, with a custom 8-inch driver and a powerful 70W RMS amplifier. Components were carefully handpicked and then painstakingly voiced as complete units to meet these demanding criteria.

The SX-120 is ideally suited to complement other models in the SX speaker range, adding a deep and rich bass extension to your music. And thanks to our decades of audio expertise, this performance is brought to you at an exceptionally reasonable price.
