I would love to take these off your hands, but I don't think I can give you what they're worth. I have been following Altec duplex auctions on EBay and would think that you could get at least $800 US (and maybe over $1K with the good crossovers) for these. I don't know if the 604K is a coveted version (I think the 8G is one of the most sought). Are the x-overs based on the Jeff Markwart design?? Are they definitely NOS? Would love to hear these in those Karlson cabs! If no one steps up and/or you don't feel like dealing with Ebay etc., ping me and maybe I can find some cash somewhere. Good Luck!
