More bass in the same space®

A high-performance design that produces dramatic bass without compromising space.

Power with control

With the sub-level control, the listener can adjust the bass up and down to suit personal preference, listening material and room characteristics.

A smart approach

The Nelson’s digital signal processing unit optimises the crossover frequency, phase and shape so the Nelson takes over seamlessly as the host speaker’s bass rolls off.

No test equipment or technical knowledge is needed to integrate Nelson into your system. It’s truly a plug-in-and-play system with only one control for bass level, which you can set to taste.
