Room length: 5.17
Room Width: 3.15
The speakers (KRK VXT8s) are facing down the length of the room. 0.30m from the back wall (solid brick) and about 0.60m from each side wall. Behind each speaker is a 4inch high density rockwool panel.
The opposite wall has 4 x 4inch rockwool panels. And each side wall has 3 panels.
The ceiling has 6 panels hanging (2 inch thick). The only section of ceiling without treatment is above the speakers. The bottom of the monitors are roughly 1 meter from the ground.
Frequencies from roughly 66hz to 109hz are very very quiet. Between 109hz and 120hz there is another dip. At 120hz there is definately a build up of frenquency. Volume stabilizes after that.
Im going to hang a panel over the speakers and move the monitors around too see if I get any joy. Any other suggestions would be lovely....
The big suspect is a metal beam on the ceiling. It sticks out by 0.54m (from the ceiling). How likely would i be that this beam is the cause of the problem?? Its about 2.40m opposite the speakers.
Sorry for the long winded post! Help!
