The D'Appolito, MTM Configuration


One speaker technology which is I think old but hasn't gotten the praise it deserves is the Joseph D'Appolito configuration.  In short, it uses a tweeter vertically sandwiched between two midwoofers.  Using two actual midranges is a variation on the theme. 

What got me thinking of this was the $220,000 speaker pair that appeared on Stereophile's coverage of the Florida Audio Expo, which made me think, fondly, of the original, 1980's era  Focal Utopia where I first heard this arrangement. 

It's a very good arrangement for those who love detail and want a speaker that's relatively easy to live with.

How about you? Have a pair of D'Appolito-like speakers ever won you over?

@erik_squires "How about you? Have a pair of D’Appolito-like speakers ever won you over?"

 

Yep, for the past 30 years. Three pairs of custom design and build, before I concluded this was it for me. Kept my last set, final build. No need for anything else. Love the sound. 👍

I really liked the Joseph Audio RM25s, but JA doesn’t seem to use the D'Appolito design anymore.

Reference the classic two slit experiment to better understand the ramifications…. of course it’s worse in 3D…. but …..

 

@gdaddy1 - I meant to discuss the web site where they have several pages of news from the Florida show. :)

In this particular case it was the Acora Acoustics VRC-1’s that made me think of all the speakers I’ve heard with this kind of arrangement, but they don’t need my help promoting them. :)  I do like their choice in midrange though, since I use it in my center. :)  I need to raise the prices!
