Speaker Coverage & SPLEvent & Production
Predict listener Sound Pressure Level (SPL) based on speaker sensitivity, amplifier wattage, and room/throw distance. Verify acoustic targets.
Listener distance reduces high-frequency levels and continuous SPL quickly in open air (6dB per doubling of distance). Indoors, late reverberation bounce shields some level, dropping off slower.
Perfect for standard live musical bands, weddings, high-impact DJ dance floors, or sporting arenas.
