About

The LBD3903-D is a 12W, general-purpose, cost effective loudspeaker for indoor use. Keyholes at the rear are provided for quick and easy wall mounting. The angled front baffle results in a better sound in the listening area.

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 loudspeaker has been tested for operation at rated power for 100 hours in accordance with IEC 268-5 Power Handling Capacity (PHC) standards.

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).
