[sdiy] Reverb opinions, please

[phillip m gallo]

Dave,

Built a "plate" reverb once using a "gong" a modified Bose 5" driver and
electret mic.   Using the "gong" made it easy as it already had a
"stand" but real plate reverbs do not have a plate with so much "mass"
with gold foil being preferred.  None the less using the gong meant i
didn't have a mounting task prior to testing the useful ness.   

I silicon rubber glued the speaker to the "bell" of the gong.  I also
silicon rubber glued the electret mic to the other side of the gong
toward the edge of the gong.  It sounded great (no longer have it as the
gong wasn't mine and after 20 years of having it surrendered it back to
the owner who wanted to use it, of all things, percussion).  Also
mounted a speaker with silicon on a Tympani head but that's another
story.

After doing it my thoughts for improvement where 1) an additional mic
located in a contrasting location for "stereo" and 2) mounting the
speaker off center to require a little less power (drove it with a 15
watt "Sanken" amp module).

Here's a ref to something a little more legit:
