Walh...i'm no being mean, but 149.3dB w/ a mofo and a "1400w" P.A. amp in a trunk car???
i have to raise the BS flag on that one. trunk cars a pretty darn hard to get loud, and i just dont see a dialy system w/ 1 15" doing 149's. (unless it was on a old mis-calibrated AC, or in the trunk) What is that box tuned to?
but all-in-all, nice boxes man. keep up the good work.
i switched systems becasue i wanted tighter bass but the ported box definatly adds the volume i wanted. now i want to go louder. marshall, i did talk to my friend tonight and he said it was not on a termlab lol i'll have to change that. he said when he got home he'd check for me.
reece, being that he makes money doing this you cant just ask him and get it for free. respect the fact hes gotta make money too and email him and for i think it was only 10$ he charges he will tell you EVERYTHING you need to know to make your box.
