    Good one. Those are diysg titans for behind screen use.

    Tiny little pro mid with an Fs of 110hz and 91db efficient. Very smooth response according to the data sheet.

    Very unusual combination of tiny size, high efficiency, smooth response. All the other pro sound 3's are less efficient or have a rising / very lumpy response. Output of course is limited.
    I have used a lot of Faital Pro drivers, I really like most of them and would love to play with this driver.

    That looks real nice, I would love to hear those!

    I have the drivers for this center, but it's just too many holes. For me.

    You could say, that its a compromise to build a CBT this way?

    I think an ideal version would have an array of little MTMs, vertically oriented, so you get reduced vertical dispersion but super wide horizontal.

    Dayton produces a high impedance ND driver for these arrays by the way - 16 or 32 ohm I think? Pretty unique offering.
    dcibel dug it up and it's crazy!

    Ah yes https://www.parts-express.com/epique...-pair--301-982
    So would there be a down side (PUN intended) to laying this on it's side or designing something
    similar (maybe shorter) for Centre duties?

    "epique arrays"?

    Show us a sketch. I'm going to think about a simple arc array; I'm not quite smart enough to design one but it might work.

    So you're trying to get a lot of output with all these midwoofers? Then the issue is finding a tweeter which can keep up. Also as I've found, the mtm on its side just doesn't give good dispersion under the best circumstances.

    Using .5 ways on the sides is sensible but it's that little array in the middle that's tricky. I needed a mid which was small and played low and loud.

    Honestly a passive cbt array would probably be best if you want big time output and super smooth dispersion in a shallow cabinet. One of those epique arrays basically.
