TOA / HB-1 Subwoofer

This is a wall / ceiling subwoofer system that uses a high power 20 cm woofer. With the Acoustic Super Woofer system enclosure, it is possible to play the ultra-low frequency range while being compact. It can be changed to high impedance by installing the matching transformer MT-S0602 (sold separately).
