Overview

 

B22SA is a high-performance active subwoofer featuring a 24bit/96kHz DSP and a 2-channel amplifier module (1350W+1350W). Designed for ground-stacked use, it adopts a band-pass horn-loaded enclosure and houses two long-excursion 18" neodymium drivers (4.5" voice coils). With powerful SPL and extended frequency response, B22SA is ideal for large-scale sound reinforcement. In INFRA mode, it complements other subs by extending low-end performance. When deployed in cardioid arrays of three or multiples of three, it achieves impressive low-frequency directivity control with reduced rear radiation. Durable plywood construction with protective coating ensures touring reliability.
