Bosch LBD3921 24 Watt Column Loudspeaker

The LBD3921-D is a 24W, general-purpose, cost effective column loudspeaker for indoor use where beaming is desirable such as meeting rooms, conference venues and canteens. A swivel wall- mounting bracket is supplied as standard.

Functions
The robust, solid MDF (Medium Density Fiber board) enclosures are covered with a durable, easy-to-clean vinyl in white or black. The ABS fronts are covered with fine woven cloth in matching color. The column loudspeakers have four dual cone loudspeaker drivers, mounted on baffle, resulting in a wide horizontal opening angle combined with a small vertical 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
The column loudspeakers can be wall mounted using the supplied swivel bracket, allowing accurate positioning. 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)
