dcofer Posted November 27, 2011 Author Report Share Posted November 27, 2011 You always go with more ported than sealed. Some people go 1:1.5ish sealed:ported. Some people go as much as 1:3 sealed:ported. Tuning is normally between 40-60. Bigger sealed is more efficient, smaller sealed is more power handling. More ported is peakier output, smaller ported is more bandwidth. That's all I can think of right now Mmkay yeah thats what my calcs and response curves were coming out like, I knew most people went ported > sealed for car applications, Im still tweaking my volume ratio and tuning frequency but doign the calcs can only show so much, Just gonna need to slap it together and throw it to the wolves and hope the design holds up. Again thanks for the replys, Ill prolly throw up a test build soon, I think the cmp8 has endured the tapered t-line long enough and needs a new home haha Quote Link to comment Share on other sites More sharing options...
dcofer Posted November 27, 2011 Author Report Share Posted November 27, 2011 I like .5sealed and 1.2 ported tuned to 41 with 14sqin per I will take that opinion and keep it in my design plot. Thanks And my guess would be after displacement. Quote Link to comment Share on other sites More sharing options...
