Thank you for responding Kodomo. Unfortunately I don't have any gear to measure the room. The room is a 5.62M (W) x 4.29M(D). The ceiling is pitched. It is 2.2M(H) where the front and back walls meets the ceiling and at the pitch of the roof it is 3.13M(H). The front wall is 5.62m. I converted a garage. Made of colorbond exterior, interior is timber and gyprock, with tiled floor on concrete slab. I have rugs on the floor. I have drawings and modelling Vicoustic did a few years ago that I can send you. It shows how the room was treated with their products. I recently bought more traps. I removed a sofa the other day, added 4 traps against the front wall. Not bad. I bought 8, but really didn't solve my problem, and started taking out the highs, so went to 4. Probably send them back though. Attaching a current pics.
