Speaker is in great shape for the year. Blue labels came in the OEM guitar cabinets, according to AI. Driver reads 5.3 ohm which is perfect. Was used in a voice wedge. It's an older model which is why the price is so cheap. Works just as good as a new one but without the expense. No holds, first to come gets it. The speaker gasket is shot, if you need one, I think I have one that has just tear on one side but in great shape, free if you want it. Specs have always remained the same, the specs from Eminence, as well as cabinet designs https://eminence.com/products/kappa_pro_15a
