Innovative, non-compromised 10" woofer.

We have developed this loudspeaker in order to provide the ultimate solution to reproduce the audio band from 30Hz to 1500Hz.

The dynamic range is higher than 105dB (at 1m) and the THD stays at 1% above 40Hz, even at the maximum cone excursion.

We exclusively assembled this loudspeaker on demand, in our French laboratory.
