Thats right. Ski hole. Got confused with all the retarded on here post lately.

 

Do a 12" in a 2:1 or 3:1 ratio 4th if you can fit it.

ok 3:1 ratio you mean ported 3 and sealed 1 right?? what would be the difference if I thorw in an isobaric 15" instead of 12"??

wouldn't I gain a Little bit on space??

too many freq at once, burn the coil, we all know, over 40-50hz, its all coilburning material.

bro, for you its everything obvious, for me not because I don't have a clue. I tried to study the whole topic, and I read everywhere that isobaric needs half the space than 1 normal driver. is that true?? if its true, would the 4th order of a doublé isobaric 15" be smaller than a single 12"??

There are many "Isobaric" designs. Still would be a massive box with 15s though.

 

If you are talking about a sealed box with a two 15s push/pull that is pretty much pointless since you are getting cancelation being confined to the truck with seats that don't fold down.

 

4th order with a 12" or 6th order with a 10" would be my answer.

I think you should get a 5 gallon plastic bucket with lid and put your sub in that, if you want it ported duct tape 2 3" pvc pics on the outside for maximum dbz

4th order with a 12" or 6th order with a 10" would be my answer.

still massive?? 😢

on oficial MTX spec sheet of my subs, it says 50liter for sealed and 70liter for ported. is this also wrong?? 70liter is a relative small enclosure, and if isobaric, should be 35liter thats a mini box.

so if I do a 4th order 70+50liter isobaric, it gives 35+25 liters.

is this a plausible calculation, or is this totally wrong??

what should be a right calculation instead??

what could be a volume for a 12"

a volume for a 15"

a volume for isobaric 15"

must not be exact, but to have an idea at least

As many days as this thread has gone on you could have downloaded a free software program called Winisd watched a couple of free you tube videos on how to use it and used your own judgment on rather or not isobaric or whatever type of enclosure design is worth doing for whatever subs.

New Idea, maybe the easiest and cheapest solution

a normal isobaric bass réflex, with an added slot, that bends both woofer and port directly into the cabin.

is this an option??
