4x10" is in good shape with average wear, nothing major, four EV 10"s in an 18"-deep, rear-ported design w/ adjustable horn. Can growl and punch all day, but play clean and clear just as well. Loud enough to knock your house down. Fortunately, it's big and rugged enough to live in afterwards. 1x15" is off the market for the moment, discovered a tear in the cone testing it tonight, sadly. Looking into a recone or replacement speaker. :^( I've owned them for a decade, but I can no longer schlep stuff so heavy, so looking for a couple light, high quality 1x12"s or similar (really want Accugroove Tri112Ls, but pretty open) plus/minus a little cash either way if necessary, or sell outright $450 obo for the 4x10". Shipping will be brutal, so a deal within an hour or so of Atlanta would be best. Thanks for looking!
