Help: Tapered T-line?


Recommended Posts

Well its not the taurus in my sig. I currently have a 2008 Chrysler 300 and Im trying to keep everything close to stock with the exception of the audio. But Id like to not tear anything up with mods. Im just trying to make a clean sounding SQ/SPL build that get loud but isn't rattle as all get out.

Now I did make a slot ported box for the 2 DC 8 m2s and it sounds good but not great. I recently built a tline for my sister's 08 Jeep Compass and was quite impressed with the results of the SA-8 t-line with 400 rms.

Ok I sketched up a couple of "tries". Basicly I'm just trying to figure out the port. (I know the height is incorrect Im not worried about that at the moment.) The lengths arn't 100% dead on either but I'll fix it after I know which to go with.. Or if Im even in the same ball park on finding the taper.

This on is just a classic t-line. No taper just the same port (5.25")

This one is the style Ronnie suggested. I adjusted inside wall of the port up 3.25" and lowerd the other end 3.25" (give or take) Why 3.25", I don't know I guess because it half of 5.25"?

This one Soapbox suggested. I started with 5.25" to 1.75" to 2.75" and ended with 5.25". Why these numbers , I don't know maybe because 5.25" / 3 is 1.75. And 1.75" + 2.75" = 5.25"

Have you considered that the box doesn't need to be a rectangle? But more of the shape of your trunk? I have attached a T-Line design that I have NOT constructed yet, but it seem to be a sound design. It was designed( of course with minor restrictions) to fit in a space that is 24"L x 26"W (for 15 3/4", then 46"W for 8 1/4") x 12.5"H. With the length of the port being about 87-88" or yielding about 38Hz tune with the Fs =37Hz of the DD-508b's I am going to use.DSCN2980.jpg
