This versatile speaker features a 15-watt multi-tap transformer for use on 70V/100V distributed systems, and is switchable for 8-ohm direct operation.

Versatile mounting options include an included ground stake for in-ground installation and an L-bracket for secure mounting on either horizontal or vertical surfaces.
