RAM_Designs Posted October 8, 2011 Report Share Posted October 8, 2011 cm^2 divided by 6.45 gets you the cone area in in^2. The cone area is measured flat across the woofer, not the actual area of the concave cone that is being used.

D-train-13k Posted October 8, 2011 Author Report Share Posted October 8, 2011 alright thanks. and Ram do you have any tutorials on sketchup? i like designing the boxes on there and seeing how they look. and doing 45's and stuff at the right angle and length is long and tedious. just wondering if you have quick methods that may help a first time user of sketchup Quote The IrishmanCheck out my build hereXL 4th order wall build logIn Progress:alpine cda HU4th order Bandpass2xl 15's1- ab 400.1 (gonna be two hopefully)4- Crescendo 8's2- xts crecendo supertweeters 2 sq super tweetsMb quart 4.125Mechman 270a alt1- xs D27003- xs XP3000 4- odessey pc1700seller feed back threadhttp://www.stevemeadedesigns.com/board/topic/136418-d-train-13k/ Link to comment Share on other sites More sharing options...
