Another adventure

I just picked up a pair of Monitor 10As on Craigslist. Unlike the 1cs I got a few weeks ago these were not in pieces and seem to be whole. Of course I had to look inside. 
What is going on with these crossovers?

Looks like they've been modded.

PoorlyLooks like they've been modded.
The 10s take pretty standard values. Looks like the used whatever they had laying aroundHome Theater/2 Channel:

Looks like someone used what they have to come up with the value needed on the caps.
If they are within tolerance %, should be okay. :question:
Instead of 12uf and 34uf, it has 12.2uf and 32uf.
I think the 32uf one may be slightly at the edge of tolerance but the 12.2's are okay.
Assuming both are 16 in there.

The guy I bought them from told me they were done at a local "reputable" speaker repair place. They do sound good. Not as good as the 1Cs, of course.Polk SDA 1C, Monitor 10A, Monitor 5jr+, RTI A3, CSI A6, TSi100, PSW505

I would have used proper values, and I wouldn't have used Bennics. There are better caps out there. Also, if you can solder consider replacing those original sand cast resistors with a Mills (roughly $4 each) or some other quality brand of non-inductive resistor.

Sounds like good advice.(bad pun) The parts for my 1cs should arrive today. The 10As will be next.Polk SDA 1C, Monitor 10A, Monitor 5jr+, RTI A3, CSI A6, TSi100, PSW505
