[QUOTE="Sean Thomas, post: 137842, member: 5801"] Re: dB calculations Still thinking.... as a guitar player, I have a 50w head plugged into a 1x12 cab and have 100dB of sound, what do I get when I plug into a 2x12, and then a 4x12? This can't be right: 1 speaker = 100dB / 2 speakers = 106dB / 4 speakers = 112dB This would assume a correllated source AND 100dB for one speaker AND 100dB for the second speaker, using the consensus from above it would be 106dB. Since that doesn't seem logical, I now have to assume that the equation is wrong. 100dB measured from the first speaker, then changing to a 2x12 does NOT add another 100dB of correllated sound. What is the equation in the case of 2x12 and 4x12? [/QUOTE]
