Speaker Coverage Width Calculator
Distance (m): 10 Coverage angle (°): 90
- Coverage width (m)
- 20.000000
- Half-width (m)
- 10.000000
Width = 2 × distance × tan(angle / 2). Distance is measured perpendicular to the coverage plane along the speaker axis. This is a symmetric geometric footprint, not a prediction of sound level, frequency response or room coverage. Confirm manufacturer polar data and verify the installed system.
Methodology
How it works
Width = 2 × distance × tan(angle / 2). Distance is measured perpendicular to the coverage plane along the speaker axis. This is a symmetric geometric footprint, not a prediction of sound level, frequency response or room coverage. Confirm manufacturer polar data and verify the installed system.
