Given that the room is well furnished I agree with The_kid. You need to change the speakers.
Cables, vibration etc will not remove the brightness .... they are second order effects.
Improving the source (DVD player) would help but will probably cost at least $1000.
So I'd agree ... sell the triangles and invest the money towards less bright speakers. Since you bought them used you won't lose much.
