I’ve been working this issue for a couple of days now on my system. Just got a pair of Rel .s812 which replaced a single MK.
Rel customer support gave me specifics based on photos and floorplans. I tried their recommendations then did what all the videos and crawl docs etc said to do. I wasn’t really liking what I was hear across varieties of music and it was fatiguing compared to my old setup
Finally got a calibrated mic and software to figure out what was going on. Huge spike like 30+db around 35Hz at all the suggested locations. I'm guessing that the old sub wasn't adding enough energy into the room to really excite my problem modes.
After stripping my treatments out, pulled out the subs and started again. After resetting speaker position, toe in and take I was still seeing these room modes but much less. Finally starting to understand what those are. Gezz long enough.
Now I went around the room with a sub and found the peaks were less pronounced and suprisingly the bass smoothed out. Found the best spot on one side of the room the went to the other side a repeated.
What I came up with was unlike anything I’ve read. Subs are outside the speakers by at least 6 feet. 1 in a corner other side of a doorway, other mid wall. They face seemly random directions but direction seemed to really impact that peak.
Decay times came out low, average maybe 100ms.
My corner traps did nothing to help these modes. All are back in place and the system is less fatiguing them it was, still tuning. I also sent my data to GIK to get some ideas toward tweaking some other areas of interest
