Monitor Triangle Geometry

Find listening distance behind the line of an equilateral speaker pair.

Speaker-center spacing (m)

Your result

Distance behind speaker line (m): 1.03923
Each speaker to listener (m): 1.2

How this works

perpendicular distance = spacing × √3/2

Use the result carefully

A geometry starting point, not a substitute for the speaker manufacturer’s placement guidance.
