Hey guys I have a bass problem with my room, attached ARTA FR plot. I have in mind to use Limp Mass Bass Absorbers but I don't know how to tune and place at the room. I got this calculator but I don't know hot to use it: attached soft.
TIA

I'm no genius on this, but I do know that the more info you can give, the better.
I suggest you add a photo of your room, room dimensions, details of your gear, and a few more FR plots. If that bass hump only exists at one location, it might not be a big problem.
...and maybe your problem could be fixed some entirely different way. e.g. instead of:
$2000 - existing subwoofer
$1000 - bass traps
you might be better off with:
$2000 - existing subwoofer (moved to new location)
$500 - 2nd subwoofer (nearfield)
$500 - 3rd subwoofer (corner)

FR plot is at my listening position. Room is 5m x 6.5m aprox. and near 3m high.

Now, how do those two dips actually sound, and do they vary much as you move. It would be useful to have a drawing of the room showing all the relevant distances.
When I look at the last measurement I would change nothing.
If you take more low frequentie out the room your speakers wil sound thin.
I would make some damping panels on the reflection points ceiling and wall with about 5cm thick damping material.
Then your mid and top goes down.
And if it damps the topend to much you can put a thin layer of plastic on top of the damping material

Hi, not sure how I missed this thread.
My room is 3.3x3.4x2.5m and as you can imagine room modes 50-80 hz are but WERE a real problem.
Yes a 1msq of limp 10kg mlv behind each speaker took out 90% of the problem. I have nothing behind them but about 120mm air gap. I do have a 1200x450x60mm rockwool slab at the first reflection point which helps too
