Midwest Audio Fest

It’s that time audio enthusiasts! Registration for the 2019 Speaker Design Competition is now open! Visit midwestaudiofest.com for details and to list your speaker project. We are excited to see all returning participants, and look forward to meeting some new designers this year, as well! Be sure your plans include a visit to the Parts Express Tent Sale for the lowest prices of the year, and the Audio Swap Meet where you can buy and trade with other audio fans. We hope to see you this summer! Vivian and Jill

    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.
