i don't think you are going to find any plates that will exactly fit your new speakers because all have different sizes. You're gonna have to make some like i did. Its really not hard at all. Go to home depot and get some mdf or particle board stuff. draw the outline of the speaker shape onto the particle board with a pencil along with necessary screw holes. Cut that out, and you should have a big plate that looks like the top of the speaker. Now take an educated guess and draw another line like you did before (shape of the speaker top) but actually on the inside of the plate. You wanna get it so that when you cut out the inside all you will have left is a ring that your speaker will fit through. I wish i could be more detailed with pics and stuff but its a pain to take all that crap out again...its not hard once you start doing it.
