The CA81-RN is an 8-inch 2-way full-range loudspeaker with a built-in crossover and a 1-inch titanium HF driver. Built to Renkus-Heinz's exacting standards, the compact CA81-RN has an integrated 625 watt Class-D amplifier for plenty of power.

An exclusive 120° x 60° horn design provides constant beamwidth/directivity that delivers smooth high-frequency coverage across the listening area to avoid hot spots and can be rotated 90° to accommodate wide or deep listening spaces. This makes the CA81-RN ideal for mobile sound reinforcement where room dimensions change with the venue.

With 625 watts of power, the CA81-RN is well suited for use as a main PA component for live music and speech or fill coverage in larger systems.

The RN features RHAON (Renkus-Heinz Audio Operations Network) software control and monitoring with analog, AES, and Ethernet connections.
