xSub is a compact, 45 watt subwoofer which has been designed to match our existing range of products both aesthetically and acoustically.

xSub can be used with any loudspeaker or amplifier with sub-out and has the option to use wirelessly with other Blue Aura products.

Developed to enrich the TV and Music listening experience. When connected to loudspeakers with sub out, xSub is a 45 watt compact, front firing subwoofer. 

The 6.5” drive unit combined with Class D (DSP) amplification provides the extra depth of bass to complete your audio system. 

Measuring a compact 230mm², x-sub is presented in a silk, matt black finish. Primarily xSub has been developed to complement our existing products but can of course be used as a stand alone subwoofer with other manufacturer’s loudspeakers.

Designed to be unobtrusive yet capable of delivering powerful, controlled low frequencies, xSub is a natural addition to our range of products.
