Ceiling Speaker Calculator

Ceiling Speaker Calculator
How do I...

To calculate the number of ceiling speakers required for your project, enter the room dimensions, Extron ceiling speaker model, anticipated type of playback content, and allowable variance in sound level between speakers. Results can be viewed and printed by selecting the VIEW/PRINT COVERAGE MAP button in the Results section. The Ceiling Speaker Calculator also determines the amplifier power necessary to drive the speakers.

FAQs

The ceiling speaker calculator estimates sound pressure level (SPL) and coverage based on speaker sensitivity, power, and listening distance.

Use this calculator when designing distributed ceiling speaker systems for program audio, music, speech or background audio applications.

Yes. The ceiling speaker calculator is commonly used for 70 V and 100 V distributed audio systems.

No. The calculator assumes free‑field conditions and does not account for reverberation or ambient noise.
