Never heard of it before, but here's what (little) they have to say for themselves about their
technology.
From what I can gather reading the site, it's a signal processor that is supposed to add phase delays and distortion to the audio signal that are supposed to negate the phase delays created by the speaker crossover. Sort of like a Linkwitz transform in phase space. So if your speakers have a huge low frequency phase delay, this would alter the frequency response of the signal to delay the mid and upper frequencies such that after the crossover adds the LF delay, the response at the voice coil is in phase. So you have to dial in the amount of correction for each of the low, mid, and high frequencies until it sounds better, correct? Since it can't know your crossover slopes it can't know what you phase response is, so you'd have to dial it in by trial and error I would think. It also has a boost at the extreme high and low frequencies. Sounds like a reasonable approach to correct for the collective downstream phase errors, but I have no idea if it works as claimed, having never heard one in action. But their client list is impressive. And of course if it makes a positive difference for you, it was worth it, no?
