For $260 that's pretty good. Make sure they come with the original box and have a serial number on the box. I paid $312 for one after tax with warranty, and I got one hell of a deal... so yeah, $260 is good.
I'm sorry, but you've got to be kidding me. A single 8W7 has an output like an average best buy 12" sub. The piston area and xmax of the 8W7 is da mn impressive as well. The size of the speaker does not automatically make it better. You can find a name brand 12 that sucks or a sweet 8 for $260. Also, considering the average retail for an 8W7 from an authorized dealer is going for $350, I would say $260 is an exellent option if the warranty is still there. For SPL, I hit 136db (TL mic) with two of those 8s with only 500W.
