spl box size for btl-18 recomendation

[bigpopa 0]

a question for the man shawn fleming and any body else that know about spl boxes.for spl only,which box would be louder for a btl-18 with 5000 watts.a 6.2cf box with 98 inches of port,tuned to 64 hz.

7 cf box with 114 inches of port at 64 hz or a 8.5 cf box with 138 inches of port tuned at 64 hz also.for spl burps only.this setup is going in a astro van,4-btl's 18's.trying to find best box config.with port on driver side.all thoughts are welcome and valued.thanks BP.

Id offer my 2 cents but as soon as I saw "Astro"... Shawn is the only real authority on that one.

im not sure on this one, and certainly wait till shawn or nick awnser for you, but ive personally heard some of the smaller, peakier box's will put up the best burp numbers so i would say that the loudest of those would be the smaller one
