fritosaregood Posted September 10, 2009 Report Share Posted September 10, 2009 really i dont know there prety beefy you need to know the fs and sd to make a proper tline. also you wont have a volume. just one continous line i think the sd of most 8's is 27 in^2 Quote seller feedback: http://www.stevemeadedesigns.com/board/ind...showtopic=61719 http://www.stevemeadedesigns.com/board/ind...showtopic=68281 build log: http://www.stevemeadedesigns.com/board/index.php?showtopic=44800 Gf's build: http://www.stevemeadedesigns.com/board/topic/54346-kickergirls-camaro-new-box-pg-5/#entry753970 Link to comment Share on other sites More sharing options...

There is no chamber really, its one long continuous port. ok i'll help.... whats the subs fs and sd? You need alot more info than that to do a good design. What about the Qes Qms and Qts. Those can make or break a t-line from my understanding. Quote woman..cant live with em...cant shoot em...guess were all fucked You might be a Redneck if you use your leftover gutters for a speaker box port... YOU JUST LOST THE GAMER.I.P.

banginchevybu Posted September 10, 2009 Author Report Share Posted September 10, 2009 they are some 8s out or a jvc boom box with the sub on each end Quote Haha. Dude look at your diet.

aznboi3644 Posted September 11, 2009 Report Share Posted September 11, 2009 Umm...t-lines dont have volumes. There is no chamber really, its one long continuous port.You need alot more info than that to do a good design. What about the Qes Qms and Qts. Those can make or break a t-line from my understanding. transmission lines do have volume. And there can be a chamber...its called a chambered t-line. People have been building them for years and years. The line ratio can be anything you want...depends on the specs of the driver. the 1:1 ratio is just the "general" basic start.

aznboi3644 Posted September 11, 2009 Report Share Posted September 11, 2009 for HT I would go with a tapered line starting between 120-150% sd and tapering down to 75-100% sd Quote Link to comment Share on other sites More sharing options...
