Tuned between 40 to 42 Hz, depending on woofer displacement.

Download Torres box calculator. It makes it easy.

really need to know sub displacement to be exact. You should be @ 37hz~ though. I assumed about .3 for displacement (pair of 10"s) as you have 3ft^3 net there...

Seems like a small box for a pair of 12's... I guess I don't know those exact subs but I've always gone 2-2.5ft^3 per 12" when ported. Either way, that box will put you right around 37-38 depending on sub displacement.

i think this box is 2.13 each one and 4.2 or something combined. and i think this box doesnt have individual chambers. i mean i have them in a prefab till i make one thats suitable and there only 1.75 each so im sure a new one around 2.13 will make it sound a whole hell of alot better.

The tuning you have on that box is super high.

2.3cf box tuned to 33hz.

That's what mylows10 recommends.

what makes the tuning lower? longer port length? if i made my port longer would it lower the tuning freq?

37~ is hardly "super high". And OP, the specs you listed gives you what I said. That's not a 4ft^3+ box, its about 3ft^3 net... maybe PM someone so these newbees don't keep giving you the wrong information.
