TOA / HB-1

This is a subwoofer system for in-wall or ceiling installation, featuring a high-power 20cm woofer. Its Acoustic Super Woofer enclosure structure makes it possible to reproduce ultra-low frequencies despite its compact size. By installing the separately sold matching transformer MT-S0602, it can be changed to high impedance.
