Legacy's Bill Dudleston stands by the new Aeris speaker ($16,900/pair), which combines an AMT tweeter/supertweeter module (see below) with a dipole midrange unit and upper woofer—these have corrugated surrounds for maximum inearity—and two sealed-box subwoofers operating below 220Hz and driven by an internal 500W ICE-power class-D amp. With an AVM amplifier and CD player,the sound of Tchaikovsky's Italian Caprice was forceful and clean, though the big bass drum thwacks clipped the amplifier at the level I had chosen for the orchestral sound in the large room Legacy was using.
