The Pro System Layout

Layout of panels in the Pro system: Place all the
bottom wall modules at 2' off the floor. Absorber and diffuser units
alternate around the room to provide a mix of damping and spaciousness.
Deep
diffuser modules go on the bottom layer, and shallow ones go above that.
2D
diffuser modules go towards the front of the room. 3D diffuser modules go
towards the back of the room.
Place the first set of wall units at the first
reflection point, then place the three other units behind that. Find the
first reflection point by using a mirror. Where you see the nearest speaker
in it from the seating position is a reflection point; it's that simple!
Place the two ceiling absorber units at the first reflection points between
the speakers and the listening position.
Place the bass absorber modules in the front corners on the floor. If the
corners aren't available, place the bass modules along the front wall/floor junction.
