Looking to add one single 13w7 and run it off a jl hd1200. Need some help in deciding on a ported box. Should I build the box to jl specs which is 2.375 net volume and tuned to 34 hertz? Or should I go which a bigger box and tune a bit lower around 30-34 hertz? If I go bigger how much bigger should I go and what difference will I hear from going from jl spec to a bigger one?
