Rock Monitor 80-SM

Single speaker system with stereo L/R inputs, 3-driver, 2 x 2-way coaxially mounted high-frequency

Features & Specifications

These high-performance single-speaker systems provide two channels of L/R sound outdoors. Their Dual-Directional Soundfield™ — two tweeters, each offset at a 30° angle—and twin voice coil bass/midrange driver ensure extremely wide dispersion, a particularly important consideration outdoors where there are no walls or ceiling to contain sound.

Rock Monitors are ideal in small outdoor areas less suited to a stereo pair of speakers or where a single speaker is preferred. In large, or unusually shaped areas, multiple rock speakers can be used to eliminate sound imbalances that occur with stereo sound as people move around or are seated closer to one speaker than the other
