I have a 3.1 Cubic foot box for 2 10" type-R's. I have 3 3"(Circle) ports and cant decide how long to make them to tune them. I was wondering what you thought I should tune my box to to get the most SPL out of them (I wanna FEEL the bass more). Should I tune it to around 40 hz or something more like 34 hz. I listen to alot of rap, but I also like to listen to some other stuff on the side, Mostly rap though. Any suggestions?
