Sub12i 12" bass-reflex 400W passive installation subwoofer - Harmonic Design HDE-40055

Very compact, powerful and easy to transport passive installation subwoofer with bass-reflex port. It features a specially designed 12" woofer with a 3" voice coil that allows a wide linear excursion. Through the ventilation at the magnetic pole core, the heat development of the voice coil is dissipated optimally, thus achieving a high power handling capacity of 400 WRMS and 800 W peak. The lower heat development also means greater reliability and reduced thermal stress on the voice coil; the result is excellent dynamics and dry, controlled bass reproduction at incredible sound pressure. It does not have an internal passive cross-over, so the frequency cut must be made by the Harmonic Design system power amplifiers or by an external electronic cross-over; up to a maximum of 160 Hz (with a slope of 24 dB/oct), it guarantees the best possible transitions between subwoofer and satellite. The cabinet is made of high-quality plywood, painted to be scratch, impact and weather resistant with a finely textured finish. Two ergonomic carrying handles on the top ensure easy handling.The front of the subwoofer is protected by a rust-proof steel grille lined with internally glued acoustic foam. An M20 threaded insert on the top of the cabinet allows you to mount a pole to hook another speaker. In addition, four abrasion-resistant rubber feet on the underside ensure a secure footing. hd Sub12 is also available in a handle-less installation version without M20 thread. It can be used as a "slave" subwoofer in addition to the hd P12 stereo active subwoofer or with all power amplifiers in the Harmonic Design system to ensure reliable and accurate reproduction of low frequencies. Main features 1 x 12” long-excursion subwoofer (400 W / 800 W) Frequency response from 40 Hz Ultra-compact dimensions Deep bass extension to match the M- / ML hd series Without handles and M20 thread
