Two models of the speaker are available for use in 25 and 70 Vrms distributed systems. This speaker is supplied with wiring terminals and strain relief for inbound and outbound speaker wiring. The AM50 is designed primarily for wall mounting and includes a trim ring for adapting to any standard four-inch square or weatherproof backbox.
