Here's a picture of the caps in question. The three together are 25 MFD. The single is 75. I don't have the skillset to do the testing that was asked. I'm sorry.
You're correct. Both woofers don't work while in the cabinets. I see what you're saying about those three caps. The other speaker doesn't have those. Here is the other crossover.
Now you got me wondering about the crossovers, so I found some on ebay and mine are different. I did find a pair on...
Yes, both voice coils tested the same. Could it be a bad capacitor? The black wire is attached to the cap on the right, and the red wire to the cap above it.
I picked up a pair of RS 2.5 speakers. They are in pretty good shape but there isn't any sound coming from the woofers. All other drivers work. I pulled the woofers and both play when connected directly to the amp. There isn't anything obvious like broken solder or loose wires.
Any suggestions...
I'll post my progress. I'm hoping for oil-filled caps. I'm going to practice removing the woofer on another AR2a that has a bad cabinet before I tackle the good pair.
I have a pair of AR2a speakers that I'm going to open up and do the L pads and caps. Is it necessary to use putty to reseal the drivers or can a foam gasket be used? Thanks.
I tested the speakers last night. All the drivers work. The pots are a little scratchy. Here are some pics. I need to repair the cracks in the woofers and straighten out the screens on the tweeters.
I picked up a pair of JBL 4312A speakers for $20 at the Goodwill yesterday. Cabinets are in pretty good condition. Each woofer has a cracked diaphragm. I haven't had a chance to test them yet.
