The hd Sub18 is a compact, transportable and powerful vented subwoofer. According to extensive research in designing high-power loudspeaker chassis over the past 30 years, the new designed longexcursion chassis with 5“ voice coil and fiberglass double spider enables linear excursion up to 30 mm. Dramatically improved cooling of the voice coil through the pole piece and spider allows an extremely high continuous power rating. Improved cooling increases the durability and reliability of the subwoofer. Excellent dynamics and tight impulse response combined with outstanding sound pressure level is the result. Filtering is done by the Harmonic Design DSP platform.

The enclosure is constructed of high-quality birch multi-plywood coated with a durable scratch-, impact- and weatherproofed polyurethane finish. Equipped with two comfortable handles on the sides for easy transport and stacking. A special powder-coated steel grille with acoustic foam on the inside protects the driver. The M20 flange on top enables the possibility of placing a mid-high loudspeaker on a distance rod on top of the subwoofer. Additional rubber stacking feet at the bottom with matching receptacle on the opposing side guarantees safety stacking of multiple cabinets. Connection on the rear terminal by two Speakon NL4 on pin 2, pin1 is hard wired for linking the input signal. Optional RAL painting is available.
