I am looking for the calculations or a computer program that will tell me the parameters of putting multiple drivers in a box. For instance, if I had one 8" woofer in a .5 cubic foot box, I could use the TS parameters of the driver to calculate the response in the enclosure. Now, if I were to put four 8" woofers in a 2.0 cubic foot box, how would I figure the response of the enclosure?
