@slaw Don’t know about you Brian, but mostly when I make a significant upgrade, I find reviewing my sub settings is necessary. Of course my room is small so any change is noticed easily.
Don’t we ‘fuss with stuff’, just because? 😁 Actually I watched Steve Gutenberg this morning, and he was discussing this. Recommended a ‘tone generator’ for the phone (I usually use Vandertones for this) and I found one. Pretty cool really. but, to my astonishment, I found one of my rear corners was collecting low waves at about 10-15 db Above anywhere else at about 50db. And was also over-taking the center between the speakers. So, as I have two subs hooked in stereo, moved the one across from that bad corner build-up out and away from that speaker. Not perfect, but it reduced the build-up by a significant amount. Obviously, that could be creating a ‘muddy’ bass filled center, and rear room reflections. Interestingly, my sweet spot was not so much effected, and pretty neutral, but we also hear all those others sounds bouncing around us, good and bad. Not perfect, as only a true bass trap would fix that corner, but much more neutral across the spectrum now.
Had to find something to fool around with, it’s the weekend 😁
