[QUOTE="moparnut, post: 8646576, member: 674006"] I call mine a happy accident and I went about it wrong. It was an experiment to try building a different kind of box. I will tell you that when I built mine it showed the line should be around 9 ft (I don't recall the exact) to get a tune of 30Hz. My line is 7 1/2 ft and it is tuned to 37Hz. Also my orignal plan was to put a 10 in there so the Sd was for a 10. I have a 12 in there and it doesn't hurt the performance, in my opinion. Based on what I am experiencing on mine, I'm not sure how hard and fast the rules are on Qts and Qms. I have had RF R1 in there (not sure of the specs) and a JL Audio 12w1v3 (Qms - 8.2, Qts - 0.502). The JL breaks both of those rules, but sounded great in there on 300 watts. The PPI P.12D2 (Qms5.46, Qts - .4) absolutley outperforms the others running at 4 ohm/300 watts. It is now running at 1 ohm/900. Hopefully that gives you something to work with. [/QUOTE]
