The HDL 12-AS is the companion subwoofer for HDL 6-A. Housing a 12” woofer, the HDL 12-AS is a very compact active sub enclosure and features a 1400 W powerful digital amplifier. It is the ideal complement to create flown HDL 6-A clusters with outstanding performance. It features a built-in digital stereo crossover (DSP) with adjustable crossover frequency to connect the HDL 6-A line array module or a satellite. The integrated mechanics are both fast and reliable. The heavy-duty front grille is power-coated. A special transparent-to-sound foam backing inside helps the further protection of the transducers from dust.
