Description
 |
The LR7Bass is a double-tuned band-pass bass system, matching the LR7 line-array in both permanent and portable applications. Featuring a single 12” long excursion woofer with Neodymium magnet structure, the LR7B delivers high quality, high output bass response from an ultra-compact and weight efficient package. The concentric bandpass configuration offers LR7-tuned bass response in full-space (flown) and increased efficiency in half-space (stacked) applications
The extended frequency response enables the LR7B to be used as mid-bass reinforcement, full-range bass extension or subwoofer. The integrated flying system, combines light weight with high WorkingLoadLimit and makes for a quick system set-up in combination with the LR7 line-array module. The LR7Bass features an integrated top hat, enabling a stand-mounted “top/sub” combination together with 3 units LR7 on the BRK3LR7 bracket (option). The SIS pre-wiring ensures complete cable/connector compensation between the LR7Bass and ALC; The LR7Bass is to be used in combination with an ALC2 or ALC4 amplifier/controller, then delivering maximum sound quality and output power with dedicated and inaudible (power and excursion!) protection (SDP circuit). |
