The hd P12sti is a compact, but powerful active subwoofer for fixed installations. Its unique 12″ high excursion driver with 3″ voice coil, single rubber surround and ferrite magnet system guarantees optimal heat dissipation, thus increasing reliability. Such driver warrants excellent dynamic and bass transient reproduction. It even provides an incredible pressure, despite its very compact size. The onboard electronics provide High-End-DSP with FIR filter and three 500 W Class D power amplifiers - two amplifiers are suitable for passive speakers. The frequency range is extended downward to 40 Hz, and the headroom and dynamic behavior of bass range of the system are noticeably increased in a very efficient manner. The electronic section includes the hd MultiDSP open architecture platform, which guarantees perfect control over all relevant system components using the easy-to-use, windows based hd LevelZ remote software. This new DSP platform now enables all the processing and control functions of large sound systems in easy-to-use plug and play device providing 20 user presets, over 20 factory presets. Furthermore, using this sub, the satellite loudspeakers are exempted from low frequencies hard job. On top of the hd P12sti is an M20 threaded insert for a distance pole.
