Sorry about this.
Hallo...Thanks for the measurements in the corners.
As I suspected, according to your room dimension, width and lenght, here you have your first axiell modal resonaces and peaks at around 50Hz in your room.
The choice of the basstrapp has to reduce the peaks and ringing and the changes has to be seen in the measurement, namely, reduced peak and ringing in that particular corner where the basstrap is gonna be.
Now, you have to try different basstrapps like, MLV, VPR, Helmholtz resonators, rockwool, broadband absorbers and so on, to see what's works best.
Report back when the ringing and peaks has been reduced in the corner.
