The IBZA15 is a trapezoidal full range loudspeaker high performance, wide-bandwidth system in a compact and efficient package. Extended frequency response is provided by a bass reflex tuned 15-inch LF driver and a 1.4-inch exit compression driver (3-inch voice coil) mounted on a 80° x 50° constant directivity HF horn. This two-way system is designed for applications where very high output is required from a compact enclosure. It has been designed for use as stand-alone full-range speaker or together with a passive sub woofer (E.G. the SW215). The box houses multiple internal rigging points for ground-support, truss and wall mounting, pole mount socket, and Speakon NL4 connectors. The enclosure has been made with the latest techniques ensuring a perfect and rigid construction. Weatherized finish is provided, as the cabinet is coated with rugged Durawound texture finish and protected with specially grills.
