Dunlavy Minimum Phase Mods

Hi Everyone,

Came across an interesting virtual system here on Audiogon. The author claims (and I believe him) to have developed minimum phase crossovers.

https://systems.audiogon.com/systems/6692

It is very very rare to get to do an A/B comparison with the same speakers using minimum phase AND traditional crossover design. For instance, I can listen to a Vandersteen or Thiel, and compare them to a B&W, but that's not the same.

I'm curious if anyone has had a chance to hear them and opine as to how important this is to the final experience.

Best,

E

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. :)

Best,

E

Before I mislead you, he didn't say that exactly. Though he might(?!) have been implying it. Remember John Dunlavy was much about wave form and ergo time fidelity. In an article in Stereophile he confided that step response was his go to measurement, (I'm paraphrasing here) when the step response is good everything else will fall in place. So, hmmm?, I really don't know.

....It was rumored that many in the business found his regular numerous returns of out of acceptable spec parts annoying.
