i need 3/4 inch tho. then why do ppl like bigger boxes then?

If your port is 3 1/2" wide now, add a piece of 1/4" on the inside of it and it will be 3 1/4".

What size box depends on the application. SPL competitors use smaller boxes to take advantage of the better power handling. They also don't care about efficiency, they just want that one single note that produces the highest score. It just depends on what you're trying to achieve.

box size is relative to the QES of the sub. some prefer ported vs sealed, and of those that do, some require bigger boxes than other. for example dc and audioque like their boxes big, especially kickers, ported. where subs like DD 3500, some jbls, arcs, can be run in smaller boxes.

Smaller boxes can tollerate more power, and change the overall response of the sub. it can create more punch, than flowy bass. They CAN take more power, but also can generate more heat under circumstances. Bigger boxes, like the guy said above, offers less of a break, and the sub is easier to experience over excursion. Using programs can help determine the subs sweetspot, but cabin tuning cant be done with a modeling program easily at all. my peaks in my car are 49, 51, and 72hz. my box was around 44-45hz. depending how i tilt, move, rotate my box, changes my peak.
