AC599 is a compact 2-way full-range loudspeaker system comprised of one 384 mm (15 in) low frequency driver and one 25 mm (1 in) exit/35 mm (1.5 in) voice-coil compression driver. The horn provides 90degrees by 90degrees coverage in vertical and horizontal orientation. High-slope passive crossovers minimize band overlap and well-controlled offaxis response. The cabinet is fitted with M10 threaded suspension points. Four threaded inserts located on back of the enclosure allow attachment of an MultiMount or similar type mounting. AC599 is part of JBL's AE Application Engineered Series, a versatile family of loudspeakers for a wide variety of fixed installation applications.
