i have three 10 inch earthquake tremor subs and i wanna build a vented box for it ....there's a paper that came with it with the demensions to build one ported box, but how do i build one for three of 'em? and i don't really understand how to use the theile-small parameters, can someone explain that to me .....and when building a box for three subs, do they all share the same air space or put a divider between them? will it make a difference?

shared or divided won't make a big difference.

i still don't understand the rules of theile/small parameters, so do you think i should just build a box with three vents and devide the subs? cuz they're all gonna be wired in parallel. here's the specs.. Fs=28Hz Qms=4.726 Qes=0.483 Qts=0.438 VAS=1.6Ft 44 liters Xmax=0.5" 85dB 1W/1M Revc=6.3 Levc=6.3mH @ (1kHz) single voice coil/8ohm how would i be able to use that towards building a vented/ported box for three subs?
