bcpballer64 Posted August 16, 2011 Report Posted August 16, 2011 Have you read the sticky on them? "The strongest reason for people to retain the right to keep and bear arms is, as a last resort, to protect themselves against tyranny in government." -- (Thomas Jefferson)
Sanitarium Posted August 16, 2011 Report Posted August 16, 2011 9 foot long port with a port area of roughly 2(π6²) Good luck
Supercharged DCs Posted August 16, 2011 Report Posted August 16, 2011 9 foot long port with a port area of roughly 2(π6²) Good luck His max width should be around 4ft, so it would have to bend 2 times, right? 4ft->bend->4ft->bend->1ft. Do you think it would be possible if, say, he walled off the vehicle? I'm just curious is all. Bassless once again. Can't seem to keep a system for more than a few weeks Saving for a '06 Nissan 350z, look for build around June 2012.
brent379 Posted August 16, 2011 Author Report Posted August 16, 2011 Whoa wait how did u get 9 ft?????? Ive read quite abit on them and im havin a hard time understanding it all....i mean i can do a 9 ft port in a box but how do u go about finding how tall...deep...and wide the box should be for the,tline?? I need like a simple break down fron the,beginning...i REALLY wanna do this bad!!!!
STEvil Posted August 16, 2011 Report Posted August 16, 2011 9 feet is the length of the box because the entire box is the port. However many times you have to bend it to get the internal length to be 9 feet is up to you. 8 feet is about 35hz tuning 9 feet gets you 31.4hz. 282.5/length = tuning frequency. 282.5 is 1130 (speed of sound) divided by 4 (quarter wave theory) btw. Read the sticky... 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.
IH8PunkRok Posted August 16, 2011 Report Posted August 16, 2011 best way to design a tline is with a piece of paper (graph paper works well) and a pencil the way that work best for me is two bends. air flow goes right, then left, then forward. -Matt2005 Dodge Magnum RTJVC KD-AVX1 2 PPI S580.2 Obsidian Audio ST1 Horn Tweeters PRV 8MB450s Audio Legion 3500.1D 2 RE MT 18s 360 ah LiFePO4 BatterySHCA 2/0 155.2 @ 29 hzKicker CVR 15's buildDD 3512e buildMini T-Line Build(6) 8s BuildNightshade 15s Wall BuildMagnum AB XFL 12s BuildNewest Magnum Build
RAM_Designs Posted August 16, 2011 Report Posted August 16, 2011 Fire subs up, port exiting to the passenger side with enough room to breathe. It should be an easy down-and-back sort of design.

brent379 Posted August 16, 2011 Author Report Posted August 16, 2011 Ooooo ok im starting to get it now.. If i read the sticky right... The port length should equal or be close to the total cone area of both twelves right????
Namosh Posted August 16, 2011 Report Posted August 16, 2011 Ooooo ok im starting to get it now.. If i read the sticky right... The port length should equal or be close to the total cone area of both twelves right???? No, the port area is determined by the total cone area. The port length is determined by desired tuning.
