Ok, im building a cabinet I have 4 10" subs (this is going to be a bass cabinet) anyway all the drivers have a Vas rating 2.3 cubic feet so if i multiply 2.3 x 4= 9.2 cubic feet, This is the interior deminsion of the cabinet but my question is that I want it to be a vented enclosure, I heard that a good way to find out what the vent size should be is just to make a vent that is half the size of the driver, so if i have a 10" driver then a 5" vent is adaquate, therfore if I have 4 10" drivers a 20" vent is good, correct or do I have this all wrong?
