Bosch LBD3905 12 Watt Bi-Directional Cabinet Loudspeaker

The LBD3905-D is a 12W, general-purpose, cost effective bidirectional loudspeaker for indoor use. The baffle design creates a wide opening angle, making this loudspeaker very suitable for use in long corridors. Keyholes at the rear are provided for quick and easy wall mounting.

Functions
The robust, solid MDF (Medium Density Fiber board) enclosures are covered with a durable, easy-to-clean black vinyl. The ABS fronts are covered with fine woven cloth in matching color. The cabinet has two dual cone loudspeaker drivers, mounted on an angled baffle, providing a wide opening angle. The loudspeaker has been tested for operation at rated power for 100 hours in accordance with IEC 268-5 Power Handling Capacity (PHC) standards.

Installation/configuration notes
Three keyholes in the rear panel provide easy and quick wall mounting. A convenient, easy-to-use, 4-pole push-in terminal block is on the rear panel for on-site wiring. This terminal block has provision for power tapping on the 100-volt, matching transformer in the cabinet. It allows selection of nominal full-power, half-power or quarter power radiation (in 3 dB steps).
