Hey guys!
I was wondering about how much power i have to give in a simulation (hornresp) to simulate a stack of 4 speaker. I mean if i have a loudspeaker with 750Watts maximum power, and want to know the theoretical maximum spl with a stack of four of them, do i use the 0,5 pi for a stack of four and a system power input of 3000Watts (4x750Watts), or does it stay the 750Watt and the programm is calculating it for each box?!? thx Edited by airbell - 08 December 2009 at 12:11am |

it stays at 750W. if you want to do the sensitivity then use 0.5PI and half the voltage you would use in 2PI i.e. 1.41V rather than 2.83V. because power is V^2/R a quarter of the power is delivered but as .5PI approximates to four speakers stacked they are still getting 1W between them.
