STEvil Posted August 18, 2010 Report Share Posted August 18, 2010 I'd like to see what that middle one could do MickyMcD - "Capable of making some serious trouser flapping volumes at where's-my-testicles frequencies, the Servo-Drives used to be fairly jaw dropping..." Any time you have have a power wire next to your frame put some rubber hosing (or cut up an innertube) around it. The wire is bound to wiggle (due to driving or flex) and the casing will eventually wear through. Hammerdown... 1% no links to outside websites, business related FB/YT pages allowed.

Coleslaw Posted August 18, 2010 Report Share Posted August 18, 2010 Yea. The middle one I did for a little experiment in a coupling chamber kind of thing so the back wave comes out at the same time and place as the front wave but it really wouldn't fit well in my car (it would fit but it would be kinda weird) and I really don't know how well it would work with the walls being so short. Idk if I would want to waste the 50 dollars in wood. Link to comment Share on other sites More sharing options...
nCOMP1337 Posted August 26, 2010 Report Share Posted August 26, 2010 @coleslaw i would think the last one you showed the larger of the images, would work best, becasue it is important to have the sub as close to the port as possible i believe, the other designs although seem to be able to work fine, they seem like the sub would work harder in that environment, i think having the port opening close to the sub helps it perform but im not great at t-lines, just very interested and enjoy the math needed to make them and design them Link to comment Share on other sites More sharing options...
pervitizm Posted August 26, 2010 Report Share Posted August 26, 2010 So I've been back to the drawing board on my t-line design for a minute now. I think I've finally got it. Take a look and let me know what you think. I might start building this sometime in September.

pervitizm Posted August 27, 2010 Report Share Posted August 27, 2010 So based off of your measurements that you are saying, are you trying to create a line length that is tuned to 22 hz roughly? Roughly, here are my notes and pics of the first box I had designed using sketchup. The problem with that box was that there was no way physically that the sub could have fit inside that box. T-Line (eD 13Kv.2) To calculate length of Freq divide 1130 / (Fs freq) = Full wave Length To calculate Quarter Wave length divide (Full Wave Length / 4) Take the SD (cone area) if in cm2 (squared centimeters) convert to in2 (squared inches) 1.) 1130 / 21.5Hz = 52.55 ft – rounded to 53 ft 2.) 53 ft / 4 = 13.25 ft Q-wave length 3.) SD =545cm2 which is 84.48in2. The line has to be 84in2 So based off of what I have, I'll need a line that is around 13 feet long with a port area of around 84sq inches. Ok so I sketched up a drawing in google's sketchup. Now I didn't add the top to this but the box height with the top on is only 12inches high. So if HxWxD then the box is 12 x 45 1/2 x 27 3/4. The three drawings are of the same box just showing different measurments for what I wanted to illistrate. Now to get my 84sq of line I did a HxW of 10.5 x 8 = 84sq. So the lines wide is 8 inches high by 10 1/2 height. So based off what I had for the orignal design I tried to build the box as closely tuned to the subs's Fs as possible. I'm thinking this might be a home theater subwoofer. So should I just build the damn thing or what? 2007 Chevy Suburban LT1 Pioneer AVH 5700 DVD Diamond Audio D3 6 1/2 components Kicker 06ZX650.4 amp Kicker 06ZX2500.1 (x 2) DC Sound Lab Level 4 18's with Level 5 coils Autotek Mean Machine 400.1D (replaced) Soon to come: rims body kit flow master pipes Confuscious say "he who say it can't be done shouldn't be bothering man busy doing it" Now feel free to go crawl back under that rock and leave this to the professionals....

alaskanbass Posted August 27, 2010 Report Share Posted August 27, 2010 i finally built a tline. it was for my brother inlaw. he has a DC lvl4xl 10. he did a 143.8 with it in his kia sportage off a kicker 1000.1 clarion cz500 head unit Kinetik hc600 2 level 3 15s in a 4th order mb quart 1500.1 (for now untill i get a dc 1.2k) all knu konceptz wiring in a 2009 ford flex -DISKOLORED AUDIO- -Authorized Dealer for DC Soundlab in Alaska- Link to comment Share on other sites More sharing options...
darkmand25 Posted September 9, 2010 Report Share Posted September 9, 2010 i am trying to build a t-line, but i dont think i know where to get started. Right now I have a 13w7 in a ported box tuned to 34hz. i am pushing it with 1200 watts running at 3 ohms. it hits hard. a lot of flexing and vibrating. But i wanted to try something different. If you can give me some pointers on where to get started it would be greatly appreciated. Like i understand 1130 /23.5 = 48 / 4= 12 ft long. And my port area is 107 sq in. So does that mean that my line is gonna be 12ft long with a 10-10.4 sq in port? Link to comment Share on other sites More sharing options...
Coleslaw Posted September 9, 2010 Report Share Posted September 9, 2010 it would be 12 feet with 107 ish sq in of port. so like 11x10 or something like that Link to comment Share on other sites More sharing options...
