Had some time this week to work on something a little different...a single ten 1/4wave transmission line. It has a 1.3-1 taper ratio in the line and the "tuning" can be altered with the line stuffing. I tested it with the first half of the line stuffed at a medium density and it is amazing //content.invisioncic.com/y282845/emoticons/eek.gif.771b7a90cf45cabdc554ff1121c21c4a.gif The sound is so clean...as tight as a sealed box but with output like a good ported box. The rolloff is much more shallow than a ported box so it plays deeper for any given "tuning". I briefly did some SPL testing and it was louder than a lot of dual 12 setups I've metered for others! It really is the ultimate daily driver box! I like it enough that I decided it should be a finished product for a change.
Under construction pic (its hard to tell that there is a taper in the line, but there really is)
I'll try to get a real finished pic after the paint and clear coat dry, cause it looks really good in person. Its Aged Iron textured paint, clearcoated.
