I'm going to be brutally honest with you. If you don't have the knowledge and resources to be able to determine this answer for yourself, you have no business building a bandpass. You say you want to see what a 4th order band pass is like, all you are going to find out is what a terrible one sounds like.

However, since you are probably going to build the box anyway, to try and put some polish on this turd my suggestion is make the port have 32 sq in of area (so 4" x 8" or any other combination that comes out to 32) and 18-1/2" long. Assuming your front chamber is 1.5 cubes net, this should tune it to about 50 hz.

OP I would further advise not to do a box based on rule of thumb threads you may find here and there. Pioneer likely provided a 4th BP suggestion for your subs in the box they came in. The reponse curves they show in almost identical drivers as yours is nothing I would ever like having for myself. Their ported box looks much better IMO.

thanks, we'll all I can find is a ported box build of .7 to 1. CF.
