Well we got a lil testing done today....but shit went wrong.....we got in sweep and one burp at half volume and the dam laptop died! We managed a 145.5 sealed in the kick @ 36hz! Very happy with the results so far! Though we didn't get to test more Not bad for 1,000 to 1,500 watts and a oversized box! I spoke to Singer...and he said shrink that bish!
