Size matters

Size matters, but no one likes a big box in their living room. Smaller, whimpier subs take bigger boxes to reach the kind of output level and deep bass performance of the SDX12.


The massive motor on the SDX12 makes it possible to reach high excursion with ridiculously low distortion. When coupled with a specially designed set of T/S parameters, the SDX12 can fit in a small box and still out perform any sub in its class.


The SDX12 is ideal for small boxes in a sealed configuration or paired with dual APR12 passive radiators.

Patented XBL^2 Motor
