I have a dc level 4 15 in a 3 cu ft box tuned to 34hz, but I would like to build a new box more spl oriented. I am looking to do external aero ports to give me about 3.79 cu ft in the box and I would like to tune the box 40-45.
-What tuning would you recommend for my enclousure?
-What size aero ports would I need to acquire proper tuning and port area?
-Where on the box would be the best place to mount the aero ports?
-Will .79 cu ft make a significant difference in output?
