Just scored a pretty clean B380. The previous owner has a BX63 he will sell me for $400 but I need to wait a few months to get it. Other than collectibility and originality, is there a better, less expensive way to go? I see the newer Ashly XR1001's have a summed mono sub output I can send to my Crown PS-400 which I plan to run bridged at 680 watts. I can get that for less than half of the BX63. It's also not the A model. What would you guys do?
