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

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.
