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 0.5% above 40Hz, even at the maximum cone excursion.

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

Application example

Loudspeakers used:

Uncompromised High-End design, using 5 loudspeakers to create a true 3 ways d'Apolito system.

It covers 20 - 25000Hz (-3dB), with a sensitivity of 94dB/2,8V/1m.

We recommend digital active filter with time alignment, The crossover points are 330Hz and 3300Hz, with 36dB/Oct attenuation.

Four vents on the back side tune the enclosure at 20Hz.
