Sure, you’ll usually get a modal peak with the sub in a corner. Parametric EQ can easily fix that – it’s been the go-to remedy on the home theater forums for more than 20 years now. I’ve had corner subs in three different homes, and every one worked great after EQ. My current place, it couldn’t happen, and guess what? Now I have a nasty null. EQ can’t fix that.

Previously my subwoofer multiEQ/Audyssey curve had a 5db dip between 70-80hz after calibration. My single sub, an svs pb1000 was positioned in front of my couch between center and right speaker.
I decided maybe the couch was the cause of the problem. So I moved the sub to the right/outer side of the right speaker and toed-out about 10degrees angling closer towards the right corner of the wall behind the couch. After re-calibrating audyssey, I find 3x more dips but they are no more than 1.5 db.
Not sure what exactly was happening, but I think it sounds much better and my speakers +subwoofer sound much more controlled and less boomy.
Next I may try moving the subwoofer to the side of the couch like an end table, and point it at the rear wall behind the couch or the right side wall.
