The bass reflex design guarantees a deep, linear power response while the 4” voice coil vented design woofer offers the minimum of power compression. The system provides integrated mechanics compatible with the HDL 20-A array module.

The HDL18-AS is a compact, flyable high power subwoofer, designed to integrate seemlessly into a HDL 20-A flown array.
