The R.25-94TZ is a 2-way, full-range loudspeaker system designed to provide high quality voice and music reproduction in applications requiring extreme weather resistance. It is designed to withstand long-term exposure to tough, environmental conditions and to provide performance normally associated only with indoor loudspeakers. The R.25-94TZ has an 8-inch (203mm) cone LF driver and a ?-inch (20 mm) exit HF compression driver with a weather resistant diaphragm. The HF driver is coupled to a nominal 90? x 40? horn. The HF assembly is coaxially mounted with the LF driver. An input autoformer with switchable taps provides impedance matching to 70V or 100V lines.
