[QUOTE="Buck, post: 8760952, member: 591582"] People should also study home audio/theater 4th orders and look at the sealed and ported sizes on those. Any box should be completely custom to your specific situation. Doing boxes of rules of thumb will only get you so far with performance. IMO, 4th orders aren't really the best for SPL; it depends on the woofer and the goals. If you want to be loud with a bandpass, I usually recommend a series 6th order. The ported box advice given above with the ported boxes with external round ports is solid, for sure. You can get loud with a 4th order bandpass, but I'm not sure it's the best way to do it, usually. 145 db out of a single 1500w 12 is a pretty high goal to have, IMO. I wouldn't expect for a setup like that to be good on music. [/QUOTE]
