In Reply to: RE: Can a simple crossover (cap/inductor) achieve time alignment without a stepped baffle? posted by jupiterboy on July 18, 2014 at 09:31:13:
...and the published frequency response graph has nothing to do with time alignment. One needs a step response curve (like the one Sterophile publishes for speaker reviews) to determine actual driver time alignment. The tech details do say that the crossover is first order so it MAY indeed be phase aligned. But they are NOT time aligned. Most speakers are not time aligned and many people cannot hear the difference between a time-aligned and non-aligned speaker for a variety of reasons. People are much more sensitive to frequency response anomalies than they are to time and/or phase anomalies.
For me, time and phase alignment is a must for the most natural sounding reproduction. I started with Theil's but never loved their bright high end (this was back in the 1980's and the Their model 03A). Today I am quite happy with my Vandersteen 3A Sigs which get the phase and time alignment along with a natural-sounding frequency response.
