JBL 4312A

[Sir Thrift-a-Lot]

They look very nice, especially for a 20.

$20 for these was essentially free.   They are going from $600 to a grand on eBay (not that I have any plans to flip them).

Mark,
Are the 4312A woofers the exact same drivers used in L100s?

I haven't pulled them yet, but if not exactly the same they are very similar.   Do you have a trick for repairing a tear in that white stuff?

Those look great.  I picked up a pair of AR3 speakers at the Red White and Blue store, that were pretty much in that condition for the same price.  Best pick from the thrift I ever had. 

Ive heard some using coffee filter with some fabric glue on the back side of the speaker to repair small tears.  I also believe that Simply Speakers has a recone kit for those in the range of 55 to 90 dollars, if you wanted to go that route.

Good luck and grats on a great find.

I've done quite a few torn cones from behind with coffee filter paper, thinned Aileens and a foam brush.   What I'm specifically wondering with these is if there is a good way to make the repair invisible from the front.   I was hoping there was some way to get that Aquaplas to melt or soften so it could be brushed back together seamlessly.   I haven't found any info like that, but at Lansing Heritage I saw a couple people who use flat antique white acrylic paint to cover the repair and it wasn't noticable at all until you got right up on it, so I think I'm going to try that.

BTW, those cones are so stiff that I heard no appreciable buzzing, even at pretty good volumes with electronic music.   Plus they are ported so there isn't much back pressure.   The repair will be mostly for cosmetics.

Then that definitely sounds like a good plan.  Repairs that you dont really notice are the best.   Hope it works well.  Id like to see how that antique paper turns out.

I'll try to remember to get before and after pictures.
