    Sony's new OLED TV's are using exciters (actuators). They call it "Acoustic Surface Technology".

    This thread has been pretty quiet. Maybe to fire things up a bit, here's a link to my local newspaper and a story about what University of Rochester students are doing with flat-panel speakers.
    UR professor Mark Bocko and two of his grad students created technology for high fidelity flat-panel loudspeakers.

    I just received the same exciter DAEX32U-4 for use in a new project. I'm going to turn these three stretched canvas prints into a left, right, center sub panel wireless rechargeable bluetooth speaker system.

    Guys I got two Ultras https://www.parts-express.com/dayton...4-ohm--295-235 I'm testing as I consider replacements for my left and right surrounds, as described here: http://techtalk.parts-express.com/fo...s-as-surrounds. As I look at the Ultras, they each have what appears to be a threaded hole on the back. I've read this whole thread and haven't seen that explained. Could that be used as a mounting method? Install a threaded rod into the wall and then attach the exciter to that rod? That would seem to eliminate the common problem of how to mount these on a wall.

    My panels are 11X14 1" blue XPS, so they don't weigh much. I realize I will need to apply some felt to the wall behind them.

    Aside from inherent drum skin quality, was there another property to it that attracted you to use?

    For example - - Does the Window Film you speak of have Titanium in the ingredient list?

    - What changes do you foresee on your user end to potentially elevate this to end-all, be-all?

    - Thank You

    The window film I used was made by Frost King and was just clear plastic film that you can get at HD for about $5 per box. It is meant to help insulate windows for winter. I had the idea of trying it to create a membrane like electrostatics and plants. I am always looking for cheap experiments that most anyone can afford. The problem I ran across in the few implementations that I tried with is was the hall effect, or sounding like everything had an echo to it. I haven't experimented as much lately because I am working on a project that uses the panels as a midrange.
