So the sub alone has reasonable extension when the crossover is raised, although there is a dip in the room in the 120-140Hz range.



The mains seem to have a sharp dip at ~110Hz and ~130Hz. This...

I agree with Jerry that the hole between 100Hz and 140Hz is striking.

Is your graph of the sub with the fronts? Or is it from the sub alone?

As your amplifier is separate, you should be able...
