hi tim, i never put felt on my a25s but put a ring of 3/8" x 3/8" rubber insulation aroun the t27 in my Fried model RIIs with good success.
those $2 felt rings from madisound look ok but at $2 each, buy four and stack them if necessary and you can cut your own angles in if you feel that is better (looks like it would be).
adding the additional tweeter (the dyna dome is more like a midrange in size and sound) us highly recommended. and jim's suggested 14k xover point is good, i figured mine to be at 10k.
oh, the speaker opened up VERY nicely with the addition of the philips clear plastic dome i used (with a 0.5uF cap and potentiometer for level control).
after listening for a week or two, i remembered that the dyna tweeter might be wired out of phase to compensate for the mid suckout at their xover freq. so i tried reversing the absolute phase of just the supertweeter and WOW, it opened up again.
don't expect pinpoint imaging even though the a25s throw a decent soundstage. they never did nor never will. but on the harry james DTDs, you will get that soundstage and impact as well.
i stacked two pair as well with the supertweeter but had to use a graphic eq to bring down the bass level as they were fat there just as is the dyna a50 (two of those nice rigid paper woofers and one "tweeter".
have fun with the a25s and if you buy another pair, stack them horizontally on stands.
