Air Motion Transformer
The tweeter which functions according to the principle of the air motion transformer constitutes the heart of this loudspeaker.

Midrange Speakers
As midrange speakers, two magnetostats with outstanding acoustic-dynamic characteristics are used. Those are linked time correct to the Air Motion Transformer and to four 20cm woofers.

Especially due to their solid ceramic membrane, these chassis’ reach a particularly good decay property in their transmission range, apart from extremely low distortion values.

Ventilated Housing
The Bass/Midrange Speakers operate in a highly precisely aligned ventilated housing. This results in an in-depth and very precise bass reproduction up to 25 Hz (-3dB).

A German design patent has been applied for our loudspeaker FA.LS 1 under the official file number 40 2013 200 061.2.


The surfaces of our loudspeaker housings are elaborately coated with piano lacquer. Thus, all colours appear brilliant and deep at the same time.

In case of our model FA.LS 1 a different contrasty colour may be selected for the middle part. Special lacquering available on request.

The aluminum clip at the side can also be anodized in color according to your wishes.
