Tuning Help AQ SDC2.5

[iceman1575]

I'm trying to make a decision with how I'm going to tune my box. I originally was going to go with 35Hz, but I was thinking if 33Hz or 32Hz would be better. I'm going to be working on the port more than likely by tomorrow, so if I could, get a better suggestion. I mainly listen to hip hop/mainstream rap, some techno, some rock, etc. I tried plotting the graph in WinISD, and I don't know if it's meant more for loudspeakers, it's only showing 126dB 39Hz for two SDC2.5 12's tuned to 35Hz. Can someone enlighten me a bit as to which tuning would be better? Thanks.
