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

Here’s the (an) issue with that. They may do those nice square waves at one point in space, or maybe on a line from the speaker to the listening seat. But what about what comes out of it off-axis? All it takes is to face a speaker away from you to know that the sound level really doesn’t drop down all that much. IOW, you hear the wavefronts that leaves the speaker off-axis -- not just the one going out perpendicular to the baffle. Linear or minimum phase only makes sense with a coaxial or point source speaker, otherwise it’s just a techno-game (IMO).
