[QUOTE="Jroo, post: 7989689, member: 574112"] I know some of you have seen these and a few used one. I have an old design for a 1508 and the guy that did mine is no longer or answering emails. I have been asking around about T lines for SA8s earlier, and gathering all the info I can get and find on the line portion. I have the math close enough to get the line right, but have a few questions about the bandpass/sealed section. The biggest thing I was told to get it right was "design the subs to be in a sealed box, use a program like WINISD or Bass box to find the box Q- peak freq, and work on a quarter wave line from there." So basically get the sealed portion and just do the line length off that. So quick question folks! 1) Anyone modeled or can model a SA8 and know the box Q- peak freq? I need somebody to help me out on the sealed section size? After I have that and the sealed size so I can do the line after. Anyone please care to help a lost in the sauce man out? [/QUOTE]
