So, I'm designing myself a bandpass box for 2 15" old school Autotek Mean Machines but I'm not sure what a good sealed to ported ratio would be. I read the ideal for spl would be 1:0.825. What do you guys use for a ratio for daily bumpin?

Oh, and btw I'm going to tune the port to around 50 hertz if that has any factor into the ratio.
