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.

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

erik, I reply not as an engineer but as someone who owned Duntech speakers for 19 years, auditioned several Duntech and DAL models, and had the pleasure of personal conversations with John on two occasions.

John Dunlavy was one of our most respected speaker designers.  He believed strongly in the benefits of time/phase coherent speaker designs and so all his models were based upon that.  To achieve that time/phase coherency with his multi-driver speakers required a rather complex crossover.

My advice would be to leave the stock crossover as is, or else find some other brand if you aren't satisfied with the Dunlavy and do your experimenting with that.  I believe you will only mess up your Dunlavy and likely ruin them for resale.
