Nice. I like the accordion paper surrounds. They've got a better chance of lasting forever than anything else I've seen.

They are Electro Voice SP12's ,have a pair just like them in Aristocrat cabinets .

i put the minimum bid on em, as if i can afford any more crap around here. i figure the scrap metal in those frames alone will pay for it
i did search a bit on the sp12, and most of my hits found ancient stamped-frame alnico coaxial models...

I have both the alnico and the ferrite versions , the ferrite are mor common.

so do the speakers impress you at all, or just so-so? i wouldn't mind maybe trying to make a version of klipsch heresys(i always spell that wrong) using some nice 12 inchers

They vey nice with 8hd horns and T35 tweters . If you win them and need apair of T35' i have acouple extra pairs .

thanks! those tweeters are probably way out of my league though...

man, i just might end up with these monsters !
i kinda thought some people would be bidding on them. hm.

Those drivers appear to be a late version of the Electro-Voice SP12b. They have slightly different specs than the SP12, which was available in a chrome basket (earlier version) or in white (later version). I built a pair of EV Aristocrats for a pair of EV 12TRXb two-way drivers. I upgraded the drivers to the 12TRX, and then upgraded again to a 3-way (SP12, T25, and JBL 2404H). If you build Aristocrats (plans available online), I suggest you place the tweeter on top of the speaker unless you ears are located on your knees.

I posted a picture of my Aristocrats here:

Green Heron,
Absolutely incredible!!! You are no ordinary guy!! Vince

Beautiful work. I wish you lived closer, Heron. I'd like to get those tractrix horns on the bench for some frequency response measurement. Oh yeah, and to listen to some tunes through 'em..
