The BOSE's PANARAY 802 SERIES IV is a passive, weather-resistant loudspeaker created for many indoor or outdoor installed sound-reinforcement applications. This passive speaker uses eight 4.5" full-range drivers in an articulated array to produce a large coverage angle (120 x 100°) with a frequency range of 52 Hz to 15 kHz and a powerful 122 dB peak SPL output. The absence of tweeters and crossovers improves the speaker's overall durability and vocal quality. With a powder-coated steel grille, the enclosure is built of mineral-reinforced HDPE. For convenient fly rig deployment and installation, two Neutrik NL4 connectors are wired in parallel, with eight M8 threaded inserts fitted.
