In Reply to: Phase Coherent ... Time Aligned ... posted by andyr on February 20, 2012 at 03:07:41:
Have a look at tomservos response and you'll realize that it means no such thing.
None of the drivers acoustic centres are in the same plane and I very much doubt that Tom uses 1st order xovers yet his synergy horns are phase and time aligned as is shown by their ability to reproduce a square wave.
Also it is very difficult (or even impossible) to phase align a 1st order network.
The more honest manufacturers of these claim that the phase shift they introduce (90deg) is benign and possibly inaudible but not that they are inherently in phase.
Many, if not all, larger active monitors are electronically time and phase aligned.
Old (may be the new ones too, I don't know) AlNiCo Tannoys are phase- but not time-aligned.
In the 80s Tannoy introduced a passive all-pass filter to get them time aligned as well but even Tannoys own engineers admitted that this was purely a marketing excersise and that their cure was worse than the problem.
