Dunlavy Minimum Phase Mods

Unsound,

That's a really interesting perspective. As a DIY speaker designer, I never bothered to match drivers, and had to trust the manufacturer's provided high quality, and very consistent parts. I cannot afford to buy 100 midranges to sort.

The idea of not just using DSP for crossover and speaker design, but actually digitally compensating for minute individual differences in driver response is pretty forward thinking.

Now I have a new project. :)

That's kind of what I am asking. From a technical perspective, recreating a square wave, or near perfect impulse response with purely passive, multi-way speaker is really difficult.

Worthwhile?

For people who don’t know, Bill invented OmniMic and XSim. He knows his stuff, so questions below are for my own education. I ask all of this not really knowing if ideal phase is all that beneficial. From what I have heard, I could not tell a difference.

I’m not sure if you are arguing room acoustics or off-angle driver phase matching.

Room/Power Response
============================
You are, of course, right in the sense of the overall power response, but isn’t the goal of good speaker placement and room acoustics to have a nice delay between the initial signal and the first reflections?

Off-Angle
===========================-
Take something like the Dunlavy. Assuming your ears stayed at tweeter level wouldn’t being off-axis be fairly benign? And isn’t it better to start from "ideal" than a normal 3-way alignment?

Of course, I can see a true coaxial being ideal here, like Thiel or Kef, where the alignment stays consistent over a broad range.
