Google Sketchup: 2 15 Transmission Variation:longer Port

[quakecitystudio]

Here is another I sketched up in Google, this time with only 2 woofers and a longer port.

hella nice

how did you come up with the chamber volume???

[Applejack]

thats cool looking, make that work for an 01 blazer and ill have roscoe build it for me

What the hell? Thats just a ported box with a really long port folded a bunch of times, you need to read about 4th wave length and stuff. Here is one for an 8 inch rockford the I designed that is a true t-line.

yea a true t-line doesnt have the chamber that urs has.

and btw are u allowed to post again?

I just seen this

Thats just going to end up being a really low tuned box

If you do any chamber, you want it to be very small, maybe only like 1 cf for something like a 15"

Its called a choke as some people call it, an actual airspace that is fired in to the line, and sometimes the line beggining can be very tight

Basically start off tight, and explode in to a lrger mouth opening at the end of the line, ends up being a horn, or tapered line, depending how you design it

Even I learn something new everyday, I never would have thought about messing with a "choked" tline, until I understood what it does- explodes the air pressure in to the transmission line port

having a chamber before the line makes it a chambered t-line. People have been doing this for a while now.
