[QUOTE="Tim McCulloch, post: 137793, member: 67"] Re: dB calculations It's a little different, I think, with powered speakers. You have to treat the amp & transducer as one unit. Ivan? In a conventional system, if you add another loudspeaker wired in parallel each speaker "sees" the same drive voltage but divides the current between them. That doubling of piston area should give you +3dB. If you were to add the additional speaker and provide separate power to it, what do you think will happen, and why? Homework. [/QUOTE]
