L83+L83S system is a compact multi-purpose active DSP column system consisting of a passive full-range column speaker L83 and an active DSP controlled dual 12" subwoofer L83S.
L83 passive full-range column speaker is with 8pcs 3” neodymium full-range drivers. The drivers in L83 are arranged by elaborate calculation and Phycal™ technology to improve the coverage of vertical beam. With elaborate acoustic design, same drives in the cabinet work as one integrative full range speaker system, which can achieve perfect joint of frequency response and excellent sound performace.L83 can meet the applications in different venues and complex space.
L83S is an active DSP controlled compact subwoofer with 2pcs 12" customized Audiocenter ferrite drivers and Class D amplifier module. The system works efficiently and has built-in Bluetooth that supports multiple signal inputs.
L83S has been carefully tested. With elaborate acoustic design, innovative FTF™ LF driver design and extensive testing, the cabinet is with three-order band-pass filter. By coupling the system continually and overlaying the
resonances, the LF efficiency is improved significantly.
L83+L83S is a plug and play column system with easy set up. The presets are made with a lot of testing. The system can be put in various applications.
