What would you build and why? Im thinking about going ported for the first time. The spec sheet reccomends .35 with a 19.2 inch port for 35hz tuning or .45 with a 20.5 inch port for 30hz tuning. which tuning will sound better in a daily driver? What would happen to the tuning if I put it in .4 with a port halfway between the 19.2 and 20.5? would it change the tuning to 32.5?
