Thought I'd start a separate thread for this project. Background is here:
- The speakers are in generally very nice condition but a previous re-foam attempt was done very poorly. I tried to remove the excess glue with alcohol, then lacquer thinner. No luck. John from M_Sound has surround kits but he said the cones are just not available, so I'm hesitant to do this myself.
- AR-Pro clued me into these in the first place, and as he recommended I have sent photos to Bill LeGall at Millersound. I think this is one of those times when paying a pro to do the job makes sense. I've refoamed other speakers (most recently the JBL woofer in the wife's Toyota) but re-doing a botched job may require magic I don't have.
- The foam around the mid and tweet, held in by velcro, has rotted. The previous owner replaced them on one with what looks like A/C filter foam. Apparently AR omitted the foam on later models, so I may just leave them off.
- The crossovers will be rebuilt. RoyC had sent me a link to Erse some time back and I just ordered their Pulse-X caps for this job. Also ordered some resistors, just in case I damage any prying them out of the glue.
- The cabinets have already cleaned up very nicely with just a little sanding with #400 paper on the top of one, and an application of Howard Restor-a-Finish (using steel wool). I may use Watco Oil or maybe just Howard Feed-n-Wax.
- Will keep you posted on the progress. Here are some before shots (will delete them from the other thread).
- All comments welcome. These are not very common, so there isn't that much about them on the various forums. Here's some info I copied from other forums (and there are brochures in our Library):
- Manufacture Years: 1972 - 1978 MSRP: $850.00
Comments by Grateful on AK:
the AR-91 is a 4 ohm system. It is essentially the AR-3a with improved power handling and other refinements in a vertical cabinet. It is perhaps the best 3 way system AR ever made. They require a nice amplifier to sound their best and can absorb the full output of 300 wpc super amp on peaks
