• HELIX preserves clarity by avoiding early room reflections.
• HELIX utilizes the exclusive Wavelaunch algorithm for acoustic steering.
• HELIX broadens the listening “sweet spot” via longer projection.
• HELIX delivers greater than 120 dB of SPL full spectrum.
• HELIX utilizes separate amplification for each drive section.
• HELIX benefits from built-in stereo subwoofers powered by 750 watts of ICEpower® amplification for lower distortion and greater spatial integrity.
Helix is the world’s most advanced loudspeaker system. Building a more dynamic speaker is like constructing a greater geometric pyramid. Achieving higher peaks demands a proportionally greater base (or in this case, bass).
With assistance from component manufacturers from France, Italy and Canada, Legacy has 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 1” tweeters are splayed precisely to compliment this 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” subwoofer. This 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.
