What is the AUDAC CHA660 horn loudspeaker?
The AUDAC CHA660 is a 6.5" 2-way horn-loaded loudspeaker for long-throw reproduction of speech and music in indoor and outdoor public address systems. It handles 60 W continuous (AES) power, reaches 116 dB maximum SPL and is rated IP66 for permanent outdoor installation. A multi-tap 70/100V line transformer makes it a direct fit for distributed paging systems in campuses, sports facilities, parking structures and industrial sites.
How does the AUDAC CHA660 horn loudspeaker work?

The CHA660 combines a 1" high-frequency compression driver with a 6.5" mid/low-frequency driver, which gives clearer speech and more extended music reproduction than a traditional single-driver paging horn. Sensitivity is 99 dB at 1W/1m and the frequency response (±3 dB) covers 100 Hz – 16 kHz. Coverage is 100° horizontal by 60° vertical, so a single unit can throw announcements down a corridor, across a field or along a platform. The built-in multi-tapping transformer works on 100 V and 70 V lines, with taps of 60 W, 30 W, 15 W and 7.5 W. The tap is selected by rotating the waterproof AWX5™ connector, so no internal wiring changes are needed on site. The enclosure is UV- and impact-resistant ABS, and the included powder-coated steel bracket allows secure mounting and tilting toward the listening area. AUDAC rates the CHA660 IP66, making it weatherproof for permanent outdoor installation. Drive it from any 70V or 100V paging amplifier, and size the amplifier for the sum of the selected taps plus headroom.
