In Reply to: So does sound really slow down in a stuffed tapered Transmission line?? posted by Artesmio on September 10, 2007 at 14:19:37:
Did you ever read the articles in Speaker Builder magazine? They had some good articles on short transmission lines called short lines. I built a short line using JBL LE14A's in a four foot line with a 11.75" x 11.75" cross section area. You have to stuff the line right or it is too boomy. If you think you over stuffed it you need to put in more stuffing. You read that right, stuff it more. To me that is the key to it. It is a short line so even with a lot of stuffing it is still efficient for a transmission line. Mine sounds smooth and sails down to 20hz with no problems. I don't cross it over any higher than 1000hz and I find it very smooth. I usually use it as a sub woofer and point the drivers in the corners and cross over at 50 to 80hz.
Some say it is not a transmission line at all, but I say with the right amount of stuffing, length and cross sectional area, it slows the speed of air down to a 1/4 wavelength.
Some also say they won't handle power, but that isn't right either. It is not like a traditional transmission line as it is not tapered or as long.
