Coverage Angle / Throw Calculator
Horizontal coverage width and SPL at distance from horn angle and sensitivity.
How the coverage angle calculator works
From horn horizontal coverage angle, throw distance, sensitivity, and amplifier power, the tool estimates coverage width at the audience plane and on-axis SPL using standard logarithmic relationships.
Key terms
- Coverage angle - included angle between ?6 dB points off axis.
- Throw distance - horizontal distance from source to coverage plane.
- Sensitivity - SPL at 1 W into 1 m on axis, in dB.
Frequently asked questions
- What is horn coverage angle? The included angle between the -6 dB points off the acoustic axis, defining how wide the beam spreads.
