37hz seems too high to tune type r's imo, but if you wanna go louder i guess :eyebrow: i don't know the calculations or i'd help you out...actually i could prob find the calculations on the forums somewhere, but i gotta run to work. Ill check back after if no one has yet to respond...

yeah should be right you have 3.4cu ft tuned to 37hz. Your port takes up 1.25cu ft, and. 4.65 before displacement of port. After sub displacement your going to be at about 3 cu ft. If you could go any bigger I would.
