The TOA HB-1 Flush-Mount Subwoofer is designed to enhance low-frequency sound in commercial, residential, and retail audio systems. Its unique minimum-depth design allows discreet installation flush with ceilings or walls spaced on 16" studs. Featuring a tuned, ported enclosure and a heavy-duty 8" woofer, the HB-1 delivers high power handling with extended bass response. The acoustic bandpass filter eliminates the need for an external crossover, while the steel enclosure acts as a heat sink for durability. Additional features include a paintable grille and removable terminal block. Optional accessories include a matching transformer for distributed systems and a 900 Series Low Pass Filter Module for system equalization. The HB-1 is backed by a five-year warranty.
