The BOSE's PANARAY 502A mounted sound-reinforcement passive speaker has a full-range driver array that eliminates the need for tweeters and crossovers, resulting in outstanding vocal clarity and durability. With a wide 120° x 70° coverage, the Articulated Array design can efficiently cover small venues with a single loudspeaker, making it a cost-effective choice for many indoor voice-reinforcement applications. The Panaray 502 A can also be used with full-range music programme material when connected with optional Bose Pro subwoofers.
