Legacy Audio Helix

  • $28,000.00

Just in on trade.  One owner speakers with original wood shipping crates. External cross-over and custom made covers included.  
Includes two built in amplifiers per speaker versus standard one.  This was a factory upgrade. 
Estimated shipping weight in crates is 1000 lbs.  Items will ship by insured freight for safe delivery.  Shipping cost will be calculated based on location. 


I would venture that most of us hard-boiled audiophiles have heard a piece of equipment that was so good, so profoundly superb that you didn’t want to live without it. Many of us have been there, at the point of strain, knowing our budgetary limitations, yet yearning for the ultimate, the sound which would make us feel alive while listening. The Helix has been that product, vivifying my music every time I sit down in front of them. Ever since they were first entwined into my rig, they have been the major influence in my music having the characteristic of being alive.

Helix is the result of years of continuous auditory research and driver development 
led by Legacy Audio’s chief designer and founder, Bill Dudleston.  The HELIX speaker system applies cutting edge technologies to establish new performance standards.   HELIX utilizes the exclusive Wavelaunch algorithm for acoustic steering.  HELIX preserves clarity by avoiding early room reflections.  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.

Digital Steering

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.
