With a response more suitable for speech, these combination reflex horn speakers are ready for outdoor use, featuring phenolic resin diaphragms to avoid moisture absorption, durable off-white powder coating on the surface of the aluminium horns, and stainless steel brackets and screws.
The yoke bracket has 9mm fixing holes; connection is by means of a captive lead, 600mm long. The high-impedance models have an input impedance selector switch (four steps for 100V line, and five steps for 70V line) which facilitates impedance settings without requiring disassembly. The switch is also equipped with an off position to prevent speaker damage resulting from incorrect impedance setting during installation.
