ACTIVE SUBWOOFER

AXTON’s active subwoofers are the best choice of all for an uncomplicated bass upgrade: as an addition to an existing sound system, but also where you want to sacrifice as little space as possible and do not want to install a separate power amp. Powered bass boxes that combine amp and woofer in a single enclosure, can be installed in the trunk with very little effort and provide the bass extension down low.
