I just completed this sub this past weekend. Here is my problem and concern. The sub sounds good on music it provides a solid low end with decent definition. It is quite a bit different than my previous sub an Energy EPS 150 12" 150watt design. Movies is my concern. The sub seems to go a little lower but with a lot less punch and dynamics. It just does not provide that oomph needed in home theater. Am I missing something or is this the characteristics of this allignment? My room is 12'x24'x8' with a 3' doorway halfway down one long wall. The sub is currently placed in the front corner. The sub is connected using the line output of my receiver with a crossover of 80 hz. The crossover on the sub is turned all the way up. My only calibration tool is a RShack SP meter. I used U-571 as test material. Any suggestions would be appreciated.
