Im not too good with math and all ive used was the REcalculator which doesnt compensate for two subs. Could i just make a single ported box with the RE calc then make another, im not sure the tuning would be the same...

2 alpine type R 12's
35 hz give or take
double baffle front?
keep the box less than 17'' high

hook me up with a starting point.

not sure how much the R's can handle but lets say there will be more than enough to each, at least 750w each sub.

what is the tun on this and the cube size? if i do a baffle on the front does that make tuning go down or up?

I most likely wanted a middle port and a double baffle front, that is why i did not go with the premade box plans. Isnt that just like the same concept as prefab boxes anyway?

not to mention from 3.5-4.4 cubes the pictures are missing...

i will get the full dimensions soon. I was told to keep it shorter so that the sound could pass over the box and into the cabin.
