Oh, I don't know....I'm building a 1/4 wave T-Line for a 15 and it's about 16x17.25x48 with a 7.5x14.5 opening....= about 110 sq inches....I am considering making it 16x19.25x48 to increase that to 123...Either way the port length = about 80 inches long and that may fit in the trunk??

D-train-13k Posted October 11, 2011 Report Share Posted October 11, 2011 ur not fitting a proper t-line in a trunk. maybe an 8 would fit, but def not a 15.... and welcome! i agree. maybe a seasoned tline builder could do something like that. but for your first time i would suggest doing ALOT of research. i myself am learning more about TLines. and they are pretty large. i would suggest maybe a nice 4th order for that. its a little less complicated and will sound great. but if you do still want to attempt tline enclosures i would read the 1/4 wave tutorial that foreverbumpin posted up. its filled with alot of good information Quote The IrishmanCheck out my build hereXL 4th order wall build logIn Progress:alpine cda HU4th order Bandpass2xl 15's1- ab 400.1 (gonna be two hopefully)4- Crescendo 8's2- xts crecendo supertweeters 2 sq super tweetsMb quart 4.125Mechman 270a alt1- xs D27003- xs XP3000 4- odessey pc1700seller feed back threadhttp://www.stevemeadedesigns.com/board/topic/136418-d-train-13k/ Link to comment Share on other sites More sharing options...
masterbusa2 Posted October 11, 2011 Author Report Share Posted October 11, 2011 I mean I could careless about sound quality but I have it in a ported box and I want more bass from a custom box and again on the above questions about fs and all tht Quote Link to comment Share on other sites More sharing options...
D-train-13k Posted October 11, 2011 Report Share Posted October 11, 2011 i dont know of any other way to find FS and QTS rather than a manufacurter Quote The IrishmanCheck out my build hereXL 4th order wall build logIn Progress:alpine cda HU4th order Bandpass2xl 15's1- ab 400.1 (gonna be two hopefully)4- Crescendo 8's2- xts crecendo supertweeters 2 sq super tweetsMb quart 4.125Mechman 270a alt1- xs D27003- xs XP3000 4- odessey pc1700seller feed back threadhttp://www.stevemeadedesigns.com/board/topic/136418-d-train-13k/ Link to comment Share on other sites More sharing options...
masterbusa2 Posted October 11, 2011 Author Report Share Posted October 11, 2011 And do u think the fourth order would produce more spl than a prefab ported box? Quote Link to comment Share on other sites More sharing options...
D-train-13k Posted October 11, 2011 Report Share Posted October 11, 2011 And do u think the fourth order would produce more spl than a prefab ported box? YES a custom build box of any kind that is build correctly will out do a prefab. there are cases where a prefab will produce decent numbers. but most people on here would suggest building your own box. 4th orders can produce big numbers because they are very efficient. 90% of the numbers are all in the design of the box.
