ebay 254084635839 sold Jan 27 for $2,916.00 plus shipping, VG condition with rings on top of both, early As, but with boxes.
They don't usually get that high, most struggle to get much past $1,200.00, but most aren't very nice.
If you find it insane, you're not a collector. At least you can listen to these, people pay much more for rare postage stamps or a game baseball that will never again be used.
I'm happy with the prices, sure beats a pair of used Wilsons for half a mil, ...
They show up.
If you don't mind something more cosmetically challenged it's a bit easier, collectors want eye-candy condition.
Damn, I can actually get my $600+tax back that I spent back in '78 for my L100a's? Have all three boxes (grill box) and owners manual plus the little tag that talked about the 'Enclosure Material' and the bill of sale. I think I even have the letter sent to me from JBL in the early '80's about replacing the foam grills (don't have original foam grilles. They'd be nothing but a pile of foam 'sand' by now.) Also, a letter from the early '80's from JBL stating that JBL's are digital ready and not to worry.
The ones without foam grilles are definitely worth a lot less than the ones with new replacement foam grilles, which (and I speak from experience) are expensive and time-consuming to obtain.
Your original boxes, etc., definitely add value, but the lack of foam grilles maybe knock $300+ off the value. If you really did want to sell them, you should buy new foam grilles and get them as clean and new-looking as possible. With all that stuff, in perfect condition, you'd probably get well over $1,200 for them.
