That's not a system, that's musicDale Davies ▼ | January 18, 2013
Just take a look at this data: 145 kg (320 lbs.) each loudspeaker. That speaks volumes, so to speak. As every old audiophile know, great weight equals great quality. And it is so. Building a dynamic speaker is like constructing a greater geometric pyramid: high peaks demand a great base (or in this case, of course, bass).
Working with component manufacturers from France, Italy and Canada, Legacy Audio's mastermind Bill Dudleston developed a unique family of drivers for the Helix system. Symmetrically arrayed neodymium mid-bass and midrange drivers provide a carefully shaped directivity pattern that virtually eliminates sidewall and early floor reflections.
A pair of one inch tweeters are splayed precisely to compliment that radiation pattern. Each tweeter takes advantage of dual-pole neodymium magnets. A special lens was designed to provide acoustical impedance to the diaphragms and prevent comb filtering.
Deep bass notes emerge from the Silver-Graphite/Rohacell reinforced 15-inch subwoofer. That ultra-long throw driver is rear firing for the earliest pressurization and rarefaction. Mounted just above this rear woofer is a phase compensated, wave-terminating 15” driver which minimizes buildup of standing waves.
Helix architecture is based around a sophisticated digital time-compensating processor. Within the digital matrix, the transfer functions for each driver can be derived via summation and subtraction, parametrically equalized, and then time shifted. The result is accuracy; a totally coherent, spatially integrated, acoustic event. Custom room adjustments are readily implemented via serial/USB port.
Legacy Audio's beauty utilizes separate amplification for each drive section, uses the Wavelaunch algorithm for acoustic steering, and benefits from built-in stereo subwoofers powered by 750 watts of ICEpower amplification for lower distortion and greater spatial integrity. ■
