I do need to replace the mids.
I know the specs on these are unknown but the brand, diameter, woofer surround, bolt plate, and magnet size is so similar I decided to buy these for $20 shipped:

Why are the dust cap kits so expensive? $20 for 2 caps seems nuts. http://www.ebay.com/itm/like/290552336120?lpid=82&chn=ps
I tried the tape trick to try to pull the dent out of one cap. It did a pretty good job, but as soon as I popped the first major part of the dent out the voice coil started rubbing inside the magnet
. I pushed it back in. The speaker was probably being pulled out of shape casing the coil to rub.
I'll look at some other speakers I have, maybe there is a 4.5" dust cap I can pull off them.

I'm suspecting that both speaker cabinet crossovers are faulty. Probably the reason both mid range speakers were blown too. None of the 6 tweeters produce sound whn hooked up to the crossovers.
Do any of you have knowledge on testing or replacing components on a crossover? I'll start by replacing the caps if I can get to the board.

Try them out for sound with a trusted source other than the amp they came with to make sure, and remember to turn the Bass down all the way.
BTW, have you tested the DC offsets on that amp ? As I had mentioned, mine were shot, and that can be hazardous to a speakers' parts!
Hopin' for ya!

^ thanks for the tips.
I removed all the speakers for a full test and the results are not good.
Horns blown.
2" tweets blown.
4" mids blown.
Only speakers working were the piezo tweets mounted to the plastic fronts and the 15" woofers.
I still need to test the crossovers.
With the speakers I already have, I was able to match up a pair of 2" and a pair of 4" to mount back into the cabinets. The horns I will probably remove the blown section and glue a new tweeter to the back of the horn so I can retain the original look of the boxes. I also have a set of 4" Yamaha speakers on the way here from epay, so I won't need to use the silver 4" speakers shown below.

Good piezo tweets:

Can ya shoot me or post a pic of the back of the horn driver to see the code, and the dimensions of it ?
I am pretty sure they may be Fosters (Fostex). I have these ( a few pair, somewhere, lol) if you figure you can incorporate them onto horns. You can have them if you like and cannot find something else to work. Body of driver is 2-3/8" dia

Oh that would be awesome. Not sure on the diameter right now but here is a pic. It probably is roughly the same size as yours. Do those back ends of the horns just glue into place? I've never taken one apart before.
Here is a vid showing the inside of a Foster horn:

Doesn't look like too bad of a deal to swap out the guts.....

Little time today.
Modified the 2" tweeters I had laying around. Flattened, drilled, and trimmed the flanges.
Finished peeling off the gold dust caps from the Yamahas.
Glued the new dust caps over the old ones on the woofers and patched a tear in the surround.
Opened up the horn tweets to see the guts and found both had a broken wire 'hair'. Crazy as it sounds I managed to add a hair of wire and solder it to the existing strand. I'll test them later, maybe they will be OK.
