Posted December 11, 201113 yr i am planning on upgrading my system, but im still undecided if i should make it ported or a 4th order box, what will be the pros or cons of each, and what would be betterit will be a blowthrough on a silverado, planning for 4 15" dc lvl 4 and a dc 5k, but right now i just want to build a box first, thanks
December 11, 201113 yr A vented box is a 4th order.Do you mean a 4th order bandpass?If so, then a bandpass can have higher efficiency over a smaller bandwidth... That's about it in a nut shell.
December 11, 201113 yr If you mean in the bed of the truck below window line. Then there is no option. It has to be a 4th order bandpass.

That's about it in a nut shell.Purely out of curiosity, I know this will depend on tuning but how large is the bandpass? I know usually you would tune fairly high what would be the usable frequency and most efficient?

Same idea as a manifold enclosure used extensively in HT. Albeit it's in a ported box and not IB
December 19, 201113 yr is that your truck thats in your avitar ?? If so, I'd like to see more pics of it ...
