ADAM’s Tensor Beta Mk.II

The German ADAM company has been developing the idea of the Air Motion Transformer HF unit, originally developed by Dr. Oskar Heil. The latest version of their tweeter, the X-ART tweeter, is featured in the Mk.II version of the Tensor Beta loudspeaker ($25,000/pair), which was being demmed with Cary electronics. The X-ART tweeter is married to a folded-ribbon upper-midrange unit, a new lower midrange unit and two woofers, all mounted on a solid aluminum baffle. The enclosure is made from 1” and 2” MDF panels, extensively crossbraced. Interestingly, waffle-shaped inner panels are loosely filled with steel shot, which absorbs vibrational energy. The speaker is also supported on fluid-filled feet to further absorb vibration.
