412 CVX Posted June 1, 2011 Author Report Share Posted June 1, 2011 Common Port walls should be 'zero'. good catch. i didnt see that it doesn't change anything though. for me anyways. i think the calc assumes that round ports never have common port walls Just say no to Ground Pounder Customs. 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.

kr15 Posted June 1, 2011 Report Share Posted June 1, 2011 a local guy had a box similar to your nightshade box, that same 45 you have in the design lost on the TL after construction of that 45...never assume 45s are needed or will garner a gain Team Flex Issues Low tuning > God 2011 CALI AS1 STATE CHAMP Link to comment Share on other sites More sharing options...

Torres Posted June 1, 2011 Report Share Posted June 1, 2011 the box for the 8's, the port in the middle is 6", so when it splits off it should be 3" instead of 6". just pointing that out for future boxes Link to comment Share on other sites More sharing options...

AI James Posted June 1, 2011 Report Share Posted June 1, 2011 the part that sucks about it, is everyone thinks that every box made off in now is correct. Sure the numbers may be right but orientation of ports and subs and how the box is put together(execution) is terrible on so many of them. the slot port box...the 45 is worthless, and the port should just be the whole bottom if your that close to the sides anyhow. Also you need to know a little about what works in each car. as just having someone say they want this or that will bring failure more often then not.

Sammitch0 Posted June 1, 2011 Report Share Posted June 1, 2011 It's still a LARGE setup up from RE Box calculator and people who are using this problem are gaining knowledge. I've made almost 10 boxes since I've started using the program and it works great.
