genek Posted December 16, 2016 Report Share Posted December 16, 2016 If you buy 5/4 S2S, the actual thickness will be planed flat to about 1 1/16". Be sure you specify S2S; if you just buy 5/4 you'll get a piece rough cut to 1 1/4" thickness with surfaces that are not planed to parallel flatness.

KlausDK Posted December 16, 2016 Report Share Posted December 16, 2016 Really nice work on those 12's Glenn Regarding new fronts, this is also a possibility, and yes, the edge of the foam could have been cut nicer: Foam Grill home made BRgds Klaus Quote Link to comment Share on other sites More sharing options...
genek Posted December 17, 2016 Report Share Posted December 17, 2016 You can't get a clean cut on foam using regular blades. Straight cuts on foam are done with heated blades or wires. Any shop that sells cut-to-size foam cushions should be able to make the cuts for you (whether they'll be willing to do the cuts on foam you haven't bought from them is another matter).

I need to build new grills for a pair of AR 11's. Just a couple (three)of quick questions. When shopping for 1 in thick material, would that be what they call 5/4 in. lumber? Which Parts Express black grill cloth are you using. The Mellotone Premium or the regular Parts Express cloth. Did you consider a cross member piece between the woofer and the upper drivers. Thanks Hey Larry! The lumber was just 1 inch square pine. It took a while to find perfectly straight pieces. The fabric from PE is PN# 260-336 G-13-03-301 black speaker grill cloth. I originally bought it for the ADS 910's, but the weave pattern is much smaller, and the fabric much lighter weight than the original cloth. The frames with the corner gussets are very rigid and don't need a cross brace. I wanted to keep the front as open as possible.

ar_pro Posted December 20, 2016 Report Share Posted December 20, 2016 It's always fun to read your restoration threads, Glenn. The AR-12's look great with their new grills, and I agree that it's nice to be able to see a bit of the drivers through the cloth, much as in the AR-9 series.

JKent Posted December 20, 2016 Report Share Posted December 20, 2016 Great job. i love the grilles. Wish I'd thought of doing that for my Cizek KA-1s. The replacement foam grilles are OK but I think yours look nicer (and would have been cheaper). Keep up the good work. -Kent Quote Link to comment Share on other sites More sharing options...

The 3's grills are next! Excited to get them finished. Also grabbed a pretty nice set of AR badges that had very little tarnish off eBay.

Rich W Posted December 23, 2016 Report Share Posted December 23, 2016 Glenn, absolutely superb job on those AR-12 grills. I think they look way classier than the original foam versions. Got to do the same for my AR-11s! Thanks once again for sharing not only your restorations, but the thinking and step-by-step process that goes into them. - Rich W Quote Link to comment Share on other sites More sharing options...

I agree, these look better than the original foam grills. Superb sounding speakers, and your 11's are suppose to be even better! The grills were quick and pretty easy to do, so I expect to see some pics of yours soon! Glenn Quote Link to comment Share on other sites More sharing options...

Would a pair of AR92 woofers (200033) go in to the AR12s? If not what is the nearest match? Original AR or otherwise. I love the sound of the AR12s but feel unmistakably that the bass isn't tight enough and is letting them down. Would appreciate any advice on this. Just how rare are the AR12s? These came from the UK factory as a special order for one of the managers - lots of factory paperwork, original stands, mint cabinets, I restored the mids and purchased new grills from vintage_ar USA so worth going extra mile for the woofers.

GD70 Posted November 4, 2017 Author Report Share Posted November 4, 2017 Hi David! You're one of us lucky enough to have a set of 12's. Yours seem even more unusual being from special order! They were a one year only model, 1977, making them fairly rare. Regarding the woofers, Roy C. Would be the best person to answer compatibility but, he told me most of the AR 10 inch woofers of this era were pretty much the same with minor variations. Please post pics and of the documentation too! Glenn Quote Link to comment Share on other sites More sharing options...
david Posted November 5, 2017 Report Share Posted November 5, 2017 Hi Glenn, will do later on with pics of the speakers. The foam gaskets on the midranges are fiendishly difficult - also an odd size. Simply Speakers (or Springfield?) USA supplied some foams which worked well after a bit of snipping to fit.# The other aspect to these is the magnetic ferro fluid which can be topped up by keen restorers. In my case I ignored this and actually the mids sound OK. Just now some spare drivers cropped up on UK Ebay, a pair of tweeters and pair of mids, so of course I jumped on them. The seller told me they had come from cabinets in great condition (no or very poor grills) and again with replacement Eminence Beta woofers (will compare their specs with the AR12s sent to me) somebody had substituted for the originals due I suppose to nothing else but foam rot which is easy to repair. It's funny that owners who do that refer to it as an "upgrade" but personally I feel from all points of view, authenticity, sound and looks, it's a down grade. Need to clear a few bits and pieces away then will upload those documents and pictures. # I should have made a careful note of how these AR12 Mids refoam went as it was fairly improvised involving several stages rather than completing the job in one session, also using toothpicks at one stage to position the foam while it cured!
