    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.

      "epique arrays"?
      Guess xmax's age.

      My guess: 15. His grammar is passable. His trolling is good.

        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?

            Thanks for digging that up. Xmax, the concept seems ideal for a CC, but there is one disadvantage - you can't use the ground plane to double the length of the array.

            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.

              Incidentally, if my current design doesn't work, I may try this driver:

              https://www.parts-express.com/faital...-ohm--294-1101

              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.

                dcibel dug it up and it's crazy!

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

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

                        Perfect! That looks like you didn't make compromises, now all you need is something for left and right channels ;)

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

                            I have used a lot of Faital Pro drivers, I really like most of them and would love to play with this driver.

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