•Install the unit only in a location that can structurally support the weight of the unit and the mounting bracket. Doing otherwise may result in the unit falling down and causing personal injury and/or property damage.

•Use nuts and bolts that are appropriate for the ceiling's or wall's structure and composition. Failure to do so may cause the speaker to fall, resulting in material damage and possible personal injury.

•Tighten each nut and bolt securely. Ensure that the bracket has no loose joints after installation to prevent accidents that could result in personal injury.

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 superlow 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.
