Mega D'Appolito Speakers - The Holy Grail?


The engineer, scientist and author Dr. Joseph D'Appolito has a speaker arrangement named after him, a vertical array of mid-Woofer, Tweeter and mid-woofer. There is more to it than this, as the good Dr. has written quite a bit about crossover design needed to achieve good results.

I'm not necessarily talking about a true D'Appolito speaker though. I'm rather thinking of large speakers which have a central tweeter in between increasingly larger drivers. MBL, Dunlavy, Von Schweikert, Legacy, Gryphon all have built some version of this idea.

What do you listeners think? Is the dynamic range, detail, transparency, distortion and imaging consistently better than other type of designs?

Best,

E

I have very different opinions of some of the above mentioned speakers. Which suggests to me that perhaps some other things might be more important.
The  OP's example speakers are all fairly unique not only to each other but to most speakers in general, and some cases carry (ied) some rather lofty prices compared to most typically bought speakers. I'm not at all surprised that commonality is somewhat limited. That said; I'm not sure that the outlined driver alignment alone would necessarily have provided overwhelming commonality in more typical speakers either.
