I am trying to build the best possible box for two eclipse titanium 12's, they will be powered by an eclipse DA7232. My goal is to get a pretty good combo of sq and spl with a sealed box. My question is this: how do i know what to use as the value for qtc when calculating my box size? I've read that a number in between 0.6 and 1.1 is ok but i have also read things that contradict this. What would using larger/smaller number do to the performance of sub? Any help on this would be greatly appreciated. Thanks
