Loudspeakers used:

Dreamed system able to combine outstanding dynamic, range, subtility and very wide bandwith in reasonable size.

(speakers baffle is 180mm wide only).

It covers 30 - 26000Hz (-3dB) with  a sensitivity of 92.5dB/2,8V/1m.

The passive filter is set at 1300Hz, 12dB/Oct for the woofers, 18dB/Oct for the compression driver.

Two vents on the back side tune the enclosure at 30Hz.

Note: We improve continually our products. No contractual data.
