donquixote99 Posted June 7, 2015 Report Share Posted June 7, 2015 Here's what they looked like when I got them: None of the regular pickers at the GWO had ever seen them, apparently. So they were sitting around ignored and available when I got there. I didn't recognize them either, but I was intrigued by the heavy weight, and then I started to get it as I looked at the woofer paper. I had seen that distinctive type paper before, on some AR-93s I restored for someone. Then the notion that I'd heard of Heathkit making a speaker with AR drivers bubbled up.... GWO got $10.00 and I got the speakers.Initial testing shows 5 of six drivers functional. One tweeter open. I plan to buy some modern tweets, since the vintage ones seem to be aging out on us. Probably the HiVi Q1Rs.Both midranges sound OK, but one was missing the grill and damping from the front. I've now replaced this stuff--see seperate thread here: http://www.classicspeakerpages.net/IP.Board/index.php?showtopic=8433&hl=The woofers match, and bear the part number 401-155 AR. That's the Heathkit part number. They both also have inventory tags from some outfit called "Speakers Unlimited," that bear a date in 1989. I figure that shop redid the surrounds at that time. It's time to do it again. Here's some views of the back of one: Cabs came stuffed with this grey stuff, all torn chunks under what you see here. Not fluffy. A sort of rock wool I guess. Will replace with fiberglass. The crossovers include the famous brick capacitor. I'll put in a poly type to replace the 6 uf, but I'm not sure at this point if the brick stays or goes.... Haven't tested or pulled the pots yet, so don't know if they can be fixed up or not. Fingers crossed.All in all, about as neat a project as I ever ran into, at least since I got the AR-93s out of the same GWO. (That project led to me learning to sew....) This will go sort of slow--basically, cash is tight, so I can't buy everything at once. Will appreciate hearing how everyone feels about keeping the brick capacitor at this point (and no, can't test it, my tester only goes up tp 20 uf.)
