PA SYSTEM

[Guest]

Hello,
I DO CHOOSE/FIND A REQUIRED AUDIO WATTS FOR A CLOSED HALL

How big of room, length, width, and height? What materials are the walls and floor made of? How loud do you want it be in decibels (dBm)? Audio watts is different than power amplifier watts and speakers. Usually efficency of speaker systems is 2 to 4 % efficent. I would look at the max SPL output of the speakers at maximum power that should give you an idea at 3 feet away from the speaker. In theory in free air, Move 6 feet away, the SPL is 6 db less, go 12 feet away, another 6 db, go 24 feet away, lose another 6 db.,etc
