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?


What speakers appeared on Stereophile cover?

Too many to mention them all. Most recently did a pair of SVS Ultra for a friend. A classic design that sounds incredibly good for a very reasonable price.

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.
