And the most recent of thesethe long-defunct DuKane "blue-glow" Ionovacwas introduced 40 years ago.

Ask anyone in the street what they think of when they hear the word "loudspeaker" and odds are they'll describe a wooden box with moving-coil drivers sitting in its front. But ask a Stereophile reader and it's quite possible that he or she'll describe a large, flat panel reminiscent of a room divider: in our
