The hd P12 is a compact, transportable and powerful active subwoofer. The new designed long-excursion chassis with 3“ voice coil, fiberglass double spider, single-role rubber surround and 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. The entire electronic components are integrated into the enclosure. All relevant inputs and outputs are neatly placed on an aluminium control panel the back side. Being the ideal low frequency extension for hd M-Series and hd ML-Series, the hd P12 not only extends the the operating frequency range, but also the system´s headroom and dynamic range. 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. Optional RAL painting is available.
