Gard, I've tried finding the culprit of the few dips in the upper range. Not much luck. Doors, windows etc... Although it does seem to be consistently flat around the room now. I metered it along the wall parallel to the sub and theres some loss, but not more than a few Db. My sub would have no problem with the extra gain as I don't push the sub hard at all. What did you mean by trouble??
What I meant by trouble is when you put a PEQ in your line and have to compensate for dip(s), you may be in danger of blowing/overloading your sub. To raise the level, either by level on sub or gain in PEQ, you really are using the sub very hard in that frequency. If the dip is narrow it usually isn't a problem. In your case it's relatively wide, so you need to be cautious compensating that dip. The sub need to have the headroom to play 20 db higher than your maximum listening level. Since this is in a relatively high frequency and in the x-over zone, it may not be a problem. Try adjusting the sub phase too, se if that will help you.
