Okay used that WInISD box program and I had to enter my on specs for the 4 12" L5,and just wanted to make sure box will work.It is 16x22x54 internal for 11 cuft before sub a port displacement,I didnt know what size port to go with do I figured 4"would work and I figure the more ports the better? So I put in 8 4" ports that need to be 17.76 inches long which will tune it to 35hz.Does this add up? Basically I just wanna know if it will work or not. The box will be 9.38 cubic feet after displacement of subs and ports,Would it be better to go with fewer larger diameter port to save myself room?Thanks for any help
