I'll be building a new L slot ported box soon for my Power acoustik 15.I know some of you will knock on my sub but I like it so that's all that matters.Using Re's site my port will be 5.5 in wide 70sq.in of port area,just wanted to know is there a big difference between 30hz-35hz as far as tuning goes.The box will be about 4.3 cubes before disp.Going into a 2 dr cavalier.Thanks
