The hd Sub15 is a compact, easy to carry and powerful subwoofer in bass reflex tuning. The specially developed 15″ long excursion chassis with 4″ voice coil on fiberglass carrier allows a excursion of ±15 mm. Through a ventilation at the pole piece and at the spider the heat development of the coil is optimally dissipated. Therefore, an extremely high continuous power handling capacity of 1000 W / 4000 W is possible. The lower heat development also means increased reliability and reduced thermal stress on the voice coil. Excellent dynamics and dry bass reproduction at incredible pressure is the result. The filtering is done by Harmonic Design DSP amplifiers. With active crossover of 24 dB/octave up to max. 160 Hz, best possible transitions between LF and HF are achieved.
The housing made of multiplex wood is coated with a polyurea plastic coating scratch, impact and weather resistant and equipped with two transport handles. The front of the loudspeaker is protected by a rustproof, coated steel grille with internally glued acoustic foam. In addition, four abrasion-resistant rubber feet on the underside and the associated cutouts on top provide for a secure stacking of the same enclosure. On the back there is a recessed connection field with two SpeakCON NL4 sockets for connection via pin 2+/2- and forwarding of the input signal. An M20 threaded insert on the top allows the mounting of a distance rod.
Operation is as a slave subwoofer on the active hd P15 system subwoofer or on all Harmonic Design system amplifiers to ensure reliable and accurate low-frequency reproduction. The loudspeaker enclosure is available on request in RAL colors, weatherproof or as an installation version without handles and without M20 thread.
