esldude Posted July 17, 2019 Share Posted July 17, 2019 What did you use to get the measurements? As in which software. And could you show at least the lowest 300 hz. Maybe using REW or something similar. And remind us of your room dimensions. I remember you ad the sloping ceiling. And how big are the humps? Moving the speakers and/or yourself around is the first step.

I just ordered some of these ATS Acoustics Corner Bass Traps on the suggestion of @mitchco - https://www.atsacoustics.com/corner-bass-trap-b.html Here's a screenshot of 10-200 with 1/12 smoothing So something I wondered. Your peaks are more like 43 or 44 hz and 88 hz. I would think they are related. Maybe by a room dimension around 12.5 or so feet.

Popular Post esldude Posted July 17, 2019 Popular Post Share Posted July 17, 2019 I'd think it is related to the length mostly. I'd try moving them 2 ft forward or backward. 2ft forward if you are less than 6.5 feet from the rear wall. Of course I don't know where you have them and that may not be practical. Before moving them I'd shoot tones at 44 hz and 88 hz through them, and go walk around the speakers. You'll likely be able to find zones where the tones are louder vs softer. If you can find one where both tones are softer, then put the speakers there. In this case, if it is mostly the length mode, the left and right position is going to be less critical on these two humps. Of course those aren't easy to move speakers. Even if you don't move them, shoot the tones thru them and walk around to see where peaks and dips are. You may have the double whammy of speakers in a hot zone for those frequencies and your LP in a hot point for those. So you might benefit some to move your LP to a place where there isn't a peak in the problem frequencies of 88 and 44 hz. semente, 4est and The Computer Audiophile 2 1 And always keep in mind: Cognitive biases, like seeing optical illusions are a sign of a normally functioning brain.
