Eric sparked this question. Can an array consist of a bass-mid array, tweeter array, then upper-mid array? Ala D'Appilito style only horizontal. Zene

Joe's original work specified a MTM, with specified distances apart, and specified crossovers.

An array that looks like this

o
o
o
o.
o.
o.
o.
o. 0
o. 0
o 0
o 0
o 0 BIG O(sub woofer)

Where the odots are tweeters, the small o' are mids, and the right O's are woofs, isn't an MTM. And the 0's are in a separate ARRAY altogether

So I'm not sure what you mean when you invoke Joe's MTM

Can you clarify?

Array vertical columns would be standard side by side only the tweets and mids reversed, ie., mid, tweet, woofers. Zene

Yes. You see this done a lot in pro-sound line arrays where the midbass, mid and HF elements are horizontally arrayed in the individual cabs. When the cabs are stacked the acoustic centers of each frequency section are vertically aligned. My DR series horns, which are two-way 'W' folded horns with vertically aligned HF sections centered between dual midbass horn mouths to either side, are a variation on the theme.
