Clara Luna

Produced 2010-2016
Really impressive: stage, depth, speed and lightnes trough and trough. Maximized.

The Clara Luna is impressive in the massive sound stage that it is able to deliver, ranging up from the lowest frequencies to the top of what can be reproduced with such a light coherence that can not be supposed by the overall dimension of the components and the loudspeaker. The Clara Luna is a master in fact of transparency and speed. All this respecting the Music and the musicality. Without coloration and fakes in the reproduction.

The construction is hybrid: passive mid-high range in horn construction combined to an amplified 21" sub-woofer. This sub-woofer is moved by an 800W DSP corrected digital amplifier.

The mechanical construction of the loudspeaker presents big attention to the problematics of the time alignment and the delay of the DSP is balanced by an accurate positioning of the mid-range woofer on top of it.

To respect the time alignment of the top horn, we made it movable in distance and orientation.

The signal for the woofer is taken directly from the main power amplifier in order to respect the sound properties of the power amplifier.
