Re: 2 p210s4 enclosure.
with winisd there is no difference between 2.5 and ur 2.48.
according to winisd tho, 2.48 cubic foot tuned to 33.72, ur xmax of 11 is it when u go below 27hz.
someone who knows will have to chime in, but most music dont go below 30hz, and u might be ok because say something does play a 26hz tone, i dont think xmax is when a sub breaks, or starts to mess up, its actually xmech.
but like i said someone else will have to chime in cuz im not sure to be honest
