PA Loudspeakers 25W


The re-entrant flare horn is high impact, fire retardant ABS and is field replaceable – the driver employs a standard 1 3/8" -18 male thread coupling. All models have triple cable entries, and large termination areas.
The termination chamber and cover feature a threaded flameproof joint simplifying both installation and routine maintenance.
