The Adam is yet another loudspeaker manufacturer that uses drivers that are descendants of the Heil AMT tweeter. Adam's Classic Mk.3 uses what they call Accelerated Ribbon Technology (X-ART) for the midrange as well as the tweeter, and 2x7.5" HexaCone midwoofers. The Classic Mk.3 is available in passive ($7000)/pair or active ($10,000/pair) form, the latter for the studio professional market. A brief demowith Cary Audio electronicssounded convincingly full-range and dynamic. I understand that Kal Rubinson is getting a pair of these for review in Stereophile.
