1.2 Coherent Energy Transfer

Coherent energy is both an aspect of the absolute quantity of energy, and also the speed with which that energy begins and ends. Entirely new

technologies in current transfer and in magnetic field energy storage within the crossover maximizes the transient speed of the transducer, while eliminating the ringing that can give recorded music a fatiguing and etched quality.

Dynamic measurement techniques provide prediction of circuit behavior under actual musical conditions. Through these techniques, current saturation effects throughout the system are greatly reduced. Proper phasing of elements within the crossover circuitry is now achievable. With these new

technical developments, the level of inter-driver jitter (mis-timing between drivers) can be virtually eliminated.

The sonic results of this technology are stable, tightly focused images that retain their position and harmonic structure, regardless of input intensity (provided, of course, that the chain of amplification is able to deliver the quantity of energy required with great speed). The most apparent benefit of coherent energy transfer is in the rendering of bass information. Low frequencies are delivered with a clarity that reveals the subtle harmonic structure of pipe organ and bass guitar passages, while precise timing provides a coherent temporal structure throughout the frequency spectrum.
