Whatsapp for enquiry

L65+L65A system is a compact multi-purpose active DSP column system, consisting of a passive full-range column speaker L65 and a multi-channel digital power amplifierL65A with switching power supply and built-in DSP.

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, clear and clean sound. L65 can meet the reinforcement application in different venues and complex space.

L65A multi-channel digital power amplifier with switching power supply and built-in DSP is attached to the bottom of L65 and used together with L65 to meet the different requirements of various applications.

L65+L65A column system is flyable. It can be used as main P.A or as side fill, delay etc according to different applications.
