I believe that John clarified here that you are essentially correct. Boosting a null shouldn’t result in ringing that’s any (or at least much) worse than it would be if the null wasn’t there.

Thanks Wayne. I guess my point was that if cuts help with an area of higher SPL and resonance, shouldn't boost help with the opposite situation? It could be the room or a lack of low frequency capability of the subwoofers, but sometimes a little boost is useful and I do not think it would introduce resonance.
Now, there are of course other reasons to use boost judiciously or not at all, including maximizing the signal to noise ratio through the BFD (although I believe one has to look at the entire system's S/N ratio, also), and the fact that boosting a null eats up your sub amp's headroom (needlessly, if you really have a null that does not respond). However, a little boost can be used to treat a low line level output from the BFD, which was my problem with using just cuts.
Unfortunately, I think there needs to be a case-specific evaluation by each person as they tweak their system. Luckily, there forum is available to guide people along the way.
