Adam's Tensor Beta Speaker
The glory of this speaker is the upper-midrange and HF units, which are an evolutionary development of the Heil Air-Motion Transformer, which squeezes the air between its pleats. Adam's chief designer Klaus Henze worked with Dr. Oskar Heil in the early 1980s. Listening to Nils Lofgren's "Keith Don't Go" on this system, I was struck by how real the high frequencies sounded, with a silky smooth quality that did not result from the treble being rolled-off. We are planning an Adam review from Kalman Rubinson.
