they seem to go quickly, i have a whole bunch of stuff, but not a complete system...don't ask...looking to buy the schematic for Jantzen Crossover Kit Pair for JBL L100 Century, I have $800 worth of their parts already, so don't want to pony up the $ for more, tried to buy just the schematic from Jantzen, but they refused. Trying to sell the Crossover parts too, if anyone is interested, take $200 for the whole bunch, plus shipping, weighs 45 lbs! email for pic and list, will sell separately too. Will trade for one of these subs too.
