The R.5-66TZ two-way, full-range loudspeaker system is engineered to provide quality full-range sound projection in a variety of outdoor and indoor applications. It is designed to withstand exposure to tough, environmental conditions and to provide performance normally associated only with indoor loudspeakers.

Its wide range, smooth frequency response and high efficiency ensures both high fidelity music reproduction and superb projection of clear intelligible speech with very low distortion.

An input autoformer with switchable taps provides impedance matching to 70V or 100V lines.

The R.5-66TZ has a 12-inch (300mm) cone LF driver and a 1-inch (25 mm) exit HF compression driver with a weather resistant diaphragm. The HF driver is coupled to a nominal 50° x 50° horn. The HF assembly is coaxially mounted with the LF driver. The enclosure and HF horn are moulded from grey polyethylene. All exposed hardware is stainless steel. The Weather-StopTM grille assembly, retained by stainless steel screws to the front of the enclosure, consists of three layers.

All R-Series loudspeakers are protected by a 5 year limited component warranty and a 15 year limited enclosure warranty.
