Thanks for your help with this so far!
To begin with, to test for any significant bass information, simply uplug the Tube, fade to rear and listen for any bass. After, fade to front and compare the results.
Double check the phase of the inputs. Reverse the signals on one channel to see if the bass increases. Also, make see the Auto-Turn On Loop is disconnected (if equipped in your harness).
The last thing to check is the location and orientation of the Tube. If the Tube is not corner loaded, output will suffer greatly.
