BTW, the original question (which was never answered) was about 2 1/2
way speakers and whence they came, if anyone wants to pick up that ball.


Do you mean a d'Appolito Configuration or Array? Mine came from Scotland.

No, I don't think so. I'm not sure what a d'Appolito Configuration is.

A 2 1/2 way speaker is where you have a tweeter and two woofers, one
of which is rolled off above 400 hz or so. Usually the woofers are
the same size. This design is quite common, I've auditioned a bunch,
and liked none. Curious about the backstory...

The d'Appolito has the woofers flanking the tweeter, commonly referred
to as "MTM" ("mids" instead of "woofers"). The benefits include
increased sensitivity compared to two-way, and a relatively uniform
frequency response on-axis as well as avoiding the dreaded "Allison
Effect." I like my Linn Kabers, which are sealed-box MTM.

I'd imagine cheap TMM arrays might not be so hot, like the typical
big-box store product (Polk, etc). Some that may be okay: PSB, Quad,
Paradigm.
