Dual Driver Ceiling Loudspeakers
This 20 Watt 100V line (30W 8 ohm) dual driver ceiling
speaker is primarily aimed at installations which require
excellent music and/or voice reproduction. The Sound 20
is an ideal choice for shopping centres, leisure centres,
gymnasiums, hotels and other applications where high
performance ceiling speakers are required. This high
performance is achieved by use of a mid range driver
and tweeter combination connected by a PCB mounted
crossover to give a reliable wide range operation.
A BS5839 part 8 compliant version for voice alarm requirements
is available and comes complete with thermal fuses, high
temperature wiring, ceramic terminal block and steel firedome.
