D-train-13k Posted October 11, 2011 Report Share Posted October 11, 2011 i finally was able to meter my truck. not on a TL but hey it gives me an idea on where im at. sealed up my truck peaked at 33hz. with a 146.4 and basically from 40hz down to 28hz i stayed at a 145. with one door open at the dash and kick i pulled a 148.7 at 33hz. i have about .5ohm in rise wired to .5 ohm. so my box is pretty efficient. the build is a 2:1 ratio .75 sealed 3 ported, on two DC level 3 12's with level 4 softparts on a BC2k. tuned to 46hz with about 22 sqin per foot of port. heres a picture of what it looks like 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...

chronic2001 Posted October 11, 2011 Report Share Posted October 11, 2011 Nice! I'm a noob when it comes to 4th order but would like to try one out one day. Why is the port coming out of the top? To save internal volume or to make it longer?

D-train-13k Posted October 11, 2011 Author Report Share Posted October 11, 2011 Nice! I'm a noob when it comes to 4th order but would like to try one out one day. Why is the port coming out of the top? To save internal volume or to make it longer? yes to save internal volume but mostly because my box was not large enough. the port is close to 20 inches long. so there is still some port inside the box. but by doing this it was easier to keep my overall internal volume the same but able to change out port designs. this box was a test box to see what kind of tuning my truck liked and how efficient the design was. i started out using 3 6inpvc pipes and changed to the larger square port and it flattened my curve out alot 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...

To save internal volume or to make it longer? From what I read it makes it easier to adjust the port size and all if you've got it on the outside. Makes sense Build in progress Link to comment Share on other sites More sharing options...

chronic2001 Posted October 11, 2011 Report Share Posted October 11, 2011 That's pretty sweet u can just swap out ports. I'll have to do the same when I try a 4th order. I didn't really think of it like that. Learn something new everyday. Do you have any pics of before you put the top of the box on so I can see your subs n there?

StrongmanDesigns Posted October 11, 2011 Report Share Posted October 11, 2011 That's really similar to my box actually. Except mine is for 1 12" and meter's a tad higher. Also shares a 33hz peak sealed up and 36hz door open. I'm also running a big square port that's half in/out of box. Link to comment Share on other sites More sharing options...
