* "The SPEQ provides control of the deep bass and mid-bass sound regions to overcome room/speaker interaction effects. The SPEQ insures maximum performance in any location."

The Boundary Control is set based on how much of the space around the speaker, horizontally, is a reinforcing surface, ie, a wall. π/2 is ninety degrees, and would be chosen if the speaker is in a corner. π is 180 degrees, and is used when the speaker is against a wall. 2π is 360 degrees, and is used when the speaker is out in open space away from all boundaries. As far as I can tell.
