Plate Reverb, Prototype

So, ive knocked up a small unit, using bits of aluminum for the frame and some car body paneling for the actual plate, fixed with springs to the frame. Ive purchased some contact mics and im in the process of stripping down some old speakers to se what driver will be suitable for this prototype. However, i have spotted some alarming problems with this design so far.

This prototype only has a plate that is 9 inch by 9 inch in diameter, this may cause the problem of feedback between the driver and contact mic, also finding a driver thats small enough but to fit on the plate and accurately recreate the signal its transducing may be a problem

Other problems consist of rattles and noise's from the frame, to solve this more tension and rubber grommets will be tested.

As for the reeds that are to be fitted to the plate, il be posting diagrams soon, but on this first prototype will not be equipped with these reeds, as i can use it to demonstrate the effect, if any, the reeds have on the side of the plate reverb.
