Well, the new-old service speakers came in yesterday. Looked like they had been refoamed - one will need to be redone at some point as the glue and surround are on the underside of the cone. I took this opportunity to tighten the original binding posts, seal the cabinet interior, and recapped. The cap I took out was a royalistic 10 uf npe, and replaced with a 10 uf Auyden mkf. When replacing the speakers, I added new gasketing as well. This was fun and the outcome is extremely enjoyable. Ive always liked my Polk Monitor 7Cs, but the AR-8 is really enjoyable and really fills the high to low sonic spectrum.
Thanks for everyone's info on this forum!
