RE: Questions for JA on the "sound" of truly "time-aligned" speakers with perfect step response

Well, there is a lot of phase shift outside of the crossover region that I'm not sure benefits from correction. I've tried correction of the in-room response, and the results were bad. I've also tried correction above 200 Hz based on a gated outdoor measurement, and the results were better than stock in some ways, worse in some ways, but not a conclusive improvement.

I was thinking of taking a two-way stand-mounted loudspeaker that I like, with a 2nd order passive crossover around 2 KHz, and trying to correct the phase shift due the crossover, which is right in the ear's most sensitive region. But I would leave the rest alone. Basically, the objective would be to get the smooth phase response of a first order crossover through the transition band.
