How to read this Background on the inputs, the drawings, and the position table.

About the inputs

The calculator assumes a rigid rectangular room with one primary listening position on the centreline. Real installations have doors, lighting tracks and structural beams that constrain placement. The per-format tolerance wedges show how far a speaker can move and still meet the format.

About the drawings

Top view and side view are drawn at actual room aspect. Each speaker icon sits at its nominal target position; the faint tolerance wedges show the permissible angular range. The optional screen rectangle surfaces conflicts where speaker positions land on the screen frame.

About the position table

Angles are signed from front centre: negative left, positive right. Speakers are grouped by layer (bed, height, top). The origin key shows the front-left-floor coordinate convention.
