Have been sticking these exciters on to all kinds of things, it is a lot of fun! Haven’t tried any full size panels yet, but now have one project ready for exhibition. I thought a good use for non-intrusive panels would be for bedroom TV.
Having looked at a few forums on these panels, I decided not to worry about bass (leave that to a separate driver). I used material on hand, which did limit performance to some extent.
Part#294-224; Dayton Audio DAEX25FHE exciter
(2 in series @ 8 ohms)
Large picture frame.
A burlap coffee bean bag was used as a membrane stretched taunt across a picture frame. To this membrane, I fitted/glued a slightly smaller foam panel to which the exciters were then attached. I used battens & Liquid nails to attach the burlap (first reinforcing the frame corners with metal brackets).
Part#269-2198; Spring loaded 4 1/2″ round Terminal cup.
Tips & Tricks:
I used a spray adhesive to attach the rigid foam insulation to the burlap. TEST Materials for compatibility FIRST. I did & these are basically welded together. I am not recommending these materials, they are just what I happened to have on hand. In an attempt to dampen the “bright” performance of these drivers, I glued two layers of foam together with a free form wooden sounding board in-between. the exciters were attached to this ridged sub straight. It does dampen, but maybe not in a good way.
Generally satisfied but still tinkering. Been using a small D-amp to drive this & currently testing another exciter driver design on the right channel. Not using the Terminal cup filters at this at this time.

tttt..too much time on my hands!

I am not sure what you mean by battens. Is this what appears to be the oval to which the exciters are attached in the photograph? Is the foam suspended in the frame by the burlap?
Excellent project. Gives me an Idea on using my exciters.
