The SUB3-amp is a self powered subwoofer cabinet designed to extend the frequency range and power bandwidth of Audio Performance full-range loudspeaker systems. With a cut-off frequency of 32Hz, the SUB3-amp is made for applications where the reproduction of sub frequencies is of importance (music, sound effects).It consists of two long excursion 15 inch ND cone drivers mounted in a heavily braced vented enclosure. The SUB3-amp built-in electronics package features a new lightweight, two channel class D audio power amplifier (D2SP) designed specifically for Self-Powered products.

Key features
