SDC2.5 Tuning 36, 38, or 40hz

Hey I'm currently running a single SDC2.5 15 in a 4.5cuft box tuned to 40hz 132sq inch of port and 750rms I really enjoy it and since I do not listen to a lot of music in the low 30hz range I do not stress it much below 35hz. Just wondering what your opinons are on what I should tune my next box to, I will be adding one more SDC and doubling the box size and power.

trial and error is the only way for your own ear to judge.
PErsonally, I would do 38htz for daily.

Thanks for the input I may have to try adding to my current port to see how it sounds the lower I go, before I make the new box.

Yep, just keep playing with lengths. Might also want to try removing some air space and see if that helps at all.
