Notes:

The plan view shows the locations of traps.

Placement is flexible as long as trap stays along the same colored axis.

The 110Hz traps are placed where two axes meet. Can be placed on either.

Axes are "anti-nodes," the points of greatest air displacement.

Three 180Hz traps can be combined into one 4x8 trap for space considerations.

110 Hz traps may also be placed on any side wall, centered at 57" off of floor.
