i heard the new 12" xxx is $630 and prolly the 15" would be a little more. muddywaters i thought the new xxx was 2200wrms. why not get the new re xmx, it has 8.9 inches of excursion, weighs 81 lbs. and can handle 5000wrms, the only problem is it $5000. just curious, are you planning on selling the sx? i know someone who might be interested.
