Speaker Angle Calculator (Beta)
Built for marching bands and drum corps speaker systems, this tool helps you aim your line array speaker stacks with precision. Enter your setup and target listening point location, and get instant splay angles and diagrams to ensure powerful, even coverage from sideline to stands.
Getting Started
-
The Speaker Angle Calculator helps you figure out how to aim your line array speaker stack so that sound travels cleanly up to your target audience in the stands.
It calculates:
How far your stack is from the audience
How much vertical angle you need
The angle of each speaker in the stack to properly aim at the crowd
-
Measure these elements on-site:
How high off the ground your bottom speaker is (in feet)
How far in front of the front sideline your speaker cart is (in feet)
Where your target listening point is (judges) – measure or estimate the horizontal distance from the front sideline and how high up the seats are
How many speaker boxes are in your stack
What type of speaker you’re using (from the dropdown)
How To Use
-
Choose your line array box from the dropdown list.
This auto-fills the vertical and horizontal dispersion.
Don’t see your speaker? Choose “Custom” and type the angles manually.
-
Enter Your Stack Info
Bottom Speaker Height Above the Ground (usually 3-4 feet on a cart)
Distance in Front of the Front Sideline (how far your cart is pushed out)
-
Enter the number of line array boxes
Enter the starting angle of the bottom box (if you're using a rig with adjustable tilt)
-
Distance from the Front Sideline to the audience (where in the stands you want to hit)
Height Above Ground of that spot (e.g. 25–40 ft for mid-upper bleachers)
-
You’ll get:
The total vertical angle needed to reach your target
The splay angle per box (automatically split)
