I have the energy take 2's as my mains and the tweeter went bad on one of them. So I swapped it with another take 2 that I was got from someone else. The problem I had is when I calibrated the fronts the left was +3 and the right was +5. Usually they are within 1db of each other. So I swapped the left and right with each other. Well the left went to +5 and the right went to +3. So it seems that the replacement speaker is not as sensitive? Anyone run into this before?
