[QUOTE="mackin13, post: 2721463, member: 573274"] Turns out this involves more thinking than im used to. I dont have any trouble building a physically sound box, its just i cant seem to design one worth shit. Im trying to find out what volume i should use for my massive cw12. At first i thought i knew what i wanted and i built a box for 2 ft^3 tuned to 32. Box needs to be bigger, isnt hitting real low, but i have no idea as to how big. I tried using this formula: Vb = Qts 2.87 x 15 x Vas According to my drivers specs, my box should be 4.373 ft^3. This sounds a little big for a not so big speaker, or am i wrong? Other people on this forum run their cw12's in around 2.5 ft^3 but i am clueless as to how they determined this other wise arbitrary calculation. Some one please help. I have no trouble calculating anything else, and im so close to finishing this build, just need to re-cut my side pieces according to my boxes VB. Thanks Fs: 33 QTS: .642 VAS: 27.12 (liter?) or 1.04 (ft^3?) QL: ??? QES: 0.733 xmax: 20.5 And, any one know how to use those stupid free ware box designers? I cant seem to get windows to run mine.
