2. GENERAL DESCRIPTION
The TOA HB-1 is a high-power, wall/ceiling-mounted sub-woofer system employing a 20 cm speaker unit. Although small in size, the HB-1 provides clear super-low frequency sound reproduction thanks to its Acoustic Super Woofer enclosure construction.
3. FEATURES
•A large, 110 mm-diameter ferrite magnet, a long, 35 mm-diameter voice coil, an aluminum bobbin, and a rubber roll edge combine to permit large voice coil movement at high power input.
•The Acoustic Super Woofer system enclosure creates an acoustic band-pass filter that reproduces super- low frequencies down to 45 Hz and realizes slow-slope phase characteristics.
•The enclosure is 103 mm in depth from the mounting surface, and suitable for mounting in a wall with two- by-four construction.
•Rotating lock tabs permit the speaker to be temporarily fixed during installation. Also, the speaker has provisions for wire or bolt suspension.
•The speaker can be converted to high-impedance applications with the addition of the optional MT-S0601 matching transformer.
4. HANDLING PRECAUTIONS
No anti-magnetic provisions have been made for the HB-1 speaker. Therefore, take care to keep the unit sufficiently away from televisions, monitors or computer-related equipment.
