| You need more bass trapping. The large bass traps are good, but bass trapping is as much about coverage area. Put some more panels across the corners of the room, you have a bunch of corners.
If you don't want to over-deaden the room, then cover the panels with a thin but stiff layer, ie, FRK or even thin cardboard. That'll help absorb more bass, and restore some reflectivity to the high end. |
