Wom145_vMS provides accurate bass response in compact vented enclosure and extended frequency response.

The suspension uses the .dynamiK technology to keep excursion control in any situation.

The motor structure, engineered with FEA, uses cooper ring for very low THD.


The cone is made with our proprietary CGF material, 10 times more rigid than usual carbon fiber.

Loudspeakers used:

The .Kourtisane_5 is a bookshelves speaker using an innovative 5" woofer and 28mm soft dome tweeter.

The THD is incredibly low from 50Hz to 10000Hz, and it sounds really open and clear.


The bass response is amazing compared with the enclosure size : always clean, accurate, with affordable energy.

It can be used as demanding professional monitoring system or HiFi stereo product.
