The Legacy Helix

The AVM electronics were being used to bi-amp the midrange and treble units of the enormous Legacy Helix speakers ($48,000/pair), which use 750W ICE-powered 15" subwoofers and a digital-domain crossover with room correction, like its smaller and less expensive cousin, the Whisper XD. The big speakers lack the Whisper's unique cardioid woofers, however. The classic Radka Toneef performance of Jimmy Webb's "The Moon is a Harsh Mistress" sounded suitably delicate, but the bass on Pink Floyd's "Another Brick in the Wall" sounded ponderous, due, I think, to the sub-optimal acoustics of the air-wall ballroom.
