412 CVX Posted February 3, 2012 Report Share Posted February 3, 2012 a 4th order is essentially a sealed box firing into a ported box. here's a couple that i've designed they're really good for low notes, and are commonly used for blow through style truck boxes.

My temp system build log More box buildssome cars do over 170db with one sub, so clearly my two 12"s can do that in my car, with my knowledge too! look out bitches! I'm with captain stupid.

OldsBoomer Posted February 3, 2012 Author Report Share Posted February 3, 2012 you usually tune a 4th order around 45-55 hz lol. 30's are just way too low. the sealed section is to help with the low notes Hana he was talking about the box in the video I believe my 4th order right now is 42.5 lol my one for 4 12's would be from 39-42 Quote Suburban Coming Soon Link to comment Share on other sites More sharing options...
