One of Gershman Acoustics's dem rooms was next door to my hotel room. I was well aware, therefore, the night before the Show opened, of the pains the Canadian speaker company was taking to get the best sound from their affordable Sonogram loudspeakers (CDN$3695/pair). The result, using a system based on Audio Research CD3 Mk.2 player, LS26 preamplifier, and Reference 110 power amplifier, and Gershman's own cables was impressive.
The Sonogram combines a Peerless soft-dome tweeter with a Morel 2" dome midrange unit and and 8", American-sourced woofer that had been designed by Eli Gershman. The apparently conventional cabinet actually has a triangular-section inset running the height of the rear panel to break up internal standing waves.
