I sent some emails through ebay to that seller a while back asking about these drivers, as they had a prior listing that had a description for the 12" drivers with a title/pictures for the 15" ones. If these are the same ones as I discussed with them prior, if I remember correctly two are new and two are used/off demo.
The parent company for this seller is a commercial/PA audio custom installer (large venue work). The rep I worked with was very nice and willing to help out. I (obviously) didn't complete any business with them, but I just thought I would vouch for these folks for as far as I spoke with them about these drivers.
. . . and now that I'm thinking on it, I really have to take time to make up a trading post ad. I've got a pair of these drivers I bought from another member a while back. They were tested for working, I had Gary mill out the backs, and I put them back in the box, so not so much as even started to be broken in yet. I originally picked them up as spares for my own super-v build.
Trouble is, in January I kind of had a. . . housing malfunction. . . that destroyed my super-v cabinets along with my original pair of coaxes. The ceiling in my living room partially caved in. . . right above my gear. The cabinets, crossovers, and coaxes were a loss (I might be able to salvage some parts off of the damaged drivers which I put in a corner for whenever I can get around to them), my housing arrangement has been. . . challenging. . . at best, and any open baffle speakers I could have would end up being headphones on the couch next to me with the little living space I have left. This is actually the second time that I've put a set of cabinets for these drivers into the dumpster.
So, I don't really have the space anymore and all things considered kind of need a break on the V project. . . sorry for the little rant, but I've been out of the loop for a while and stumbled on this thread on the top of the AC home page. It just reminded me that I should probably get the extra drivers out of here before I have to move them again. . .
