Advanced FIR filtering technology is adopted to maintain the consistency of the phase of each frequency band, providing perfect clear effect and excellent uniformity of sound field. Coupled with DSP intelligent voltage limit processing, it ensures no distortion of large dynamic output. Among them, the L110 series uses the replaceable waveguide horn technology, the L206A series has the waterproof function, and the D6 series uses the high pitch and low pitch coaxial unit design. Each product has its own characteristics and unforeseen surprise are awaited.
