L65+L65S system is a multi-purpose active DSP column system consisting of a passive full-range column speaker L65 and an active DSP controlled compact single 18” subwoofer L65S.
L65 passive full-range column speaker is built with 6pcs 5" customized Audiocenter ferrite drivers and 4pcs 1" customized Beyma ferrite drivers. The drivers are designed with sophisticated measurement and arranged elaborately by physical calibration technology Phycal™ to improve vertical acoustic beam coverage. The ETE™ waveguide system developed by Audiocenter forms cylindrical wave, then couples continually, working together with customized horn design to realize the perfect joint of frequency response, which provides the accurate horizontal coverage and ensures the well-balanced, clean and clear sound. L65 can meet the reinforcement application in different venues and complex space.
L65S is an active DSP controlled compact subwoofer with one 18" customized Audiocenter ferrite driver and very powerful Class D amplifier module. L65S is with built-in Bluetooth that supports multiple signal inputs.
L65+L65S 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.
