Every seat in the room, covered.
Place your loudspeakers, aim them, and see exactly which listeners sit inside their coverage and which are left out.
Drag a loudspeaker. Watch the room respond.
A conference room with a seated audience. Each loudspeaker throws a coverage fan across the seats. Teal listeners are inside it, grey ones are not.
61 of 63 seats sit inside the loudspeakers' rated coverage angle.
Direct level varies by about 14.1 dB across covered seats.
Try it
Switch the layout, or drag any loudspeaker in the room. Each one is aimed at the middle of the audience.
Worked example: a 12 m by 8 m room, 100 degree loudspeakers, 63 seats. Preset numbers, for illustration.
A clearer picture before you hang a single speaker.
See who is covered, seat by seat
Every listener is marked inside or outside coverage, so the gaps show up before anyone sits down.
Move a loudspeaker, see it change
Slide a position or add a second unit and the covered share updates straight away.
Your own loudspeaker data
Enter the sensitivity, power and rated angle from your datasheet. We never invent loudspeaker figures for you.
Even coverage, not just loud
See how much the level varies across the seats that are covered, to help you balance positions.
A picture you can show a client
A clear plan and a 3D view that make a layout easy to talk through.

How it works and its limits
Figures are an indicative design guide only. They are not a measurement, a certification or a guarantee of how a system will perform.
Coverage is worked out from the loudspeaker data you enter: sensitivity, power, position, aim and rated coverage angle. The level falls with distance in open air, and a seat counts as covered when it sits within the rated angle. The room's own reverberation, reflections, speech clarity, vertical coverage and delay are not modelled. The cones and the room in the 3D view are an illustration.
