With a sensitivity of 100 dB (1W/1m) and a maximum sound pressure level of 135 dB SPL , the subwoofer delivers significant sonic impact while maintaining control and precision at low frequencies. The integrated DSP optimizes audio signal management, improving dynamic response, reducing distortion and protecting internal components during continuous professional use.

Distortion of less than 0,05% ensures clean, faithful reproduction of the audio signal, avoiding unwanted compression and maintaining a clear sound even at high sound pressure levels. The 20 kΩ input impedance and 0.775 V input sensitivity allow for perfect compatibility with professional mixers, audio processors, and modern PA systems.
