whats the best size for this? i was thinkin like 3 cubes, 35 sq inches of port, 3x10 slot, and tuned around 30, i will have anywhere from 6-1000 watts to mess with.

this is what i come up with

(14630000*(D/2)*(D/2))/((Fb*Fb*Vb*1728)-(1463*(D/2))

(14630000*(4/2)*(4/2))/((30*30*3*1728)-(1462*(4/2))

58520000/4665600-731

58520000/4664869

12.54

will a single 4 inch port be enuff for it? or should i do 2 4 inch ports? and i dont just divide that in half, what do i do to figure it out?

also, do i need to have something like 3.4-3.5 cubes and then after port and sub displacemnt have 3 cubes?

2 4" precision ports from http://www.partsexpress.com MINIMUM, id go with 3 or 4 daily or a 45+ SQ in slot port

well mike at soundpslinter reccomends like over 40 sq. in. of port area for a 12" so you might want to increase the port area. the volume and tuning frequencies sounds like it should work nice.
