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.
