Let me get this straight. Every room is a little different, but I was wondering about subwoofer corner placement. What is it about corner placement that is beneficial and what is poor about it? I know it can sound "boomy". Is that simply nodes , peaks or standing waves at various frequencies? Or does corner placement have nulls too? If there are less nulls with corner placement, and you have a subwoofer and an equalizer, does it not make sense to put the subwoofer in the corner and tame the peaks? From what I understand, nulls are harder to fix, and require adjusting placement mostly, but with peaks, you can trim them, correct? So proper corner placement using a good EQ means fewer or smaller nulls, and tamable peaks? Since you are reducing the peaks with an EQ, would this result in higher efficiency and/or greater headroom since you are reducing the power requirements? At least for those peaking frequencies, anyways. How many people do this and do you notice a difference in headroom or overall better frequency response?
