Picked up an older pair of JBL G-718 subs and found these loaded inside. Do these look familiar to anyone? Sticker and markings seems to indicate a possible recone at DTH of Paducah, Inc.? The boxes themselves are in decent condition and seem to be made of quality materials...and these speakers do work. Do I find and reload the cabs with the original E-155-4's, something newer and/or better, or move these boxes along as fast as I can?
