I've seen thousands of takes on acoustic treatment, monitor placement and listening position to treat a room but I wanted to see if anyone here had any tricks to finding what/where the problems are in a room.

​

I have recently moved into a new room and It seems to me to be very bassy. I have put up a couple of rockwool panels in the corners with an air gap but I'm still having problems. I mostly wanted to know if there's a way to find out what is causing the most problems, is it the corners in front or behind me, first angle of reflection or have i just gotten used to a room that lacks bass?

​

I think I've gotten to the point where i no longer trust my ears.
