Least amount of null is in between speakers. Bad on one side and worse on the other. I'm pretty sure it's just the room.

I'd never consider anything but a PEQ for something like this, but only after room treatment.

I'm thinking a panel type across the corners to start with. I'm already in good shape above 300hz.

Am I on the right track? Does filling in the corner behind the panel help/hurt low end absorbtion?

Typical decay for 200hz and below in a 16x17x8 would be?

Thanks again for all the input!
