Try miking your speakers like 1' away and see if your 120 Hz bump is still there. If so, it may be a microphone artifact@erik_squires Yep, still there even mic’d directly in front of the speaker. So to oldhvymec‘s point it could be a crossover issue or a mic artefact like you said. Unlike the other ringing in the waterfall I’m not hearing it, so I’m inclined to think it’s a mic artefact. Would love to do the same with bass traps but I think I’m already pushing my wife’s tolerance for panels.
@oldhvymec to your point, pulling them out does reduce the bass suck, but makes the peaks greater and makes the midrange less flat. Here’s an SPL graph of them pulled out (red) vs their current position closer to the wall (orange): https://www.dropbox.com/s/4rd8y9uy7jw12lb/Screen%20Shot%202021-02-22%20at%2010.06.16%20AM.png?dl=0
I have 10 GIK panels in the room right now, in retrospect the mistake I made was getting too many 2” panels and not doing enough bass traps or ceiling panels. They’re crazy expensive but one of the things that appeals to me about the PSI AVAA is that they’re easily moved and don’t require a ton of work to install.
The tough thing about renting is not wanting to overinvest in a solution for your current place, in fact our lease is up in a few months and we’re currently considering moving. I’m tempted to just to get a better room for my stereo, where I won’t need to have the LP be against a wall...
Great suggestions all, thanks for the thoughts.
