Bandpass design

[TSGP]

Also when doing size of the port Terra. A good rule of thumb is to try to get around the same size port as cone area, less is fine, just tunes it lower //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I'm doing a setup like TJs old one for 3 15s in my expedition. I'll post up some pics of the build as it goes

I think I got the perfect balance. 150 sq. in. of port, 35hz tuning, and 9.5 cubes.5 cubes sealed. good to go?

This is going to be my final plan as soon as someone confirms its a good design....
