OldsBoomer Posted March 31, 2010 Report Share Posted March 31, 2010 Ok well i've always been curious on the math that it take to tune a box. I can handel the level of math it takes just need to know the equations and varibles that are needed. also i would really love to know how to do a bandpass box desgin like a fourth order. So if anyone on here that is experienced in the math part of box designing please inform me because i'd really like to know how to do this with out the tunning calculator and be able to do it on my own. Thanks, Boomer Quote Suburban Coming Soon Link to comment Share on other sites More sharing options...
OldsBoomer Posted March 31, 2010 Author Report Share Posted March 31, 2010 can anyone explain this Quote Suburban Coming Soon Link to comment Share on other sites More sharing options...
Neo_frog Posted March 31, 2010 Report Share Posted March 31, 2010 Pretty simple actually. Problems usually arise when you build a shell then try to make port adjustments. A TI-89 is very useful because you can put other equations into the tuning formula in place of the variables so every time you changle something small, like port length, then everything in the equation updates yielding an accurate answer. Most of it is all you. As long as you can understand having 15 equations in one to make things accurate, then you'll be fine. Quote Need an install?

Reallunacy Posted April 1, 2010 Report Share Posted April 1, 2010 What is cross sectional area of the port and is length of port measured down the center of it? The math is easy, but since I'm still new to audio, I need stuff like that cleared up lol. Quote Link to comment Share on other sites More sharing options...

LxW or if you have aero ports its (Pi)r^2 Quote Suburban Coming Soon Link to comment Share on other sites More sharing options...
Reallunacy Posted April 1, 2010 Report Share Posted April 1, 2010 Awesome, thanks, did anyone know about the bandpass formula? Quote Link to comment Share on other sites More sharing options...
OldsBoomer Posted April 1, 2010 Author Report Share Posted April 1, 2010 yea thats what im curious about... doing bandpass math is deff more complex but i want to try a 4th order eventually Quote Suburban Coming Soon Link to comment Share on other sites More sharing options...
rckstar Posted April 1, 2010 Report Share Posted April 1, 2010 thank you sir much appericated i happen to have a Ti- 89 and 83 lol Hey there , Whats TI-89 and 83? Quote my motto: hit it, quit it, never admit it Link to comment Share on other sites More sharing options...
tiller1 Posted April 1, 2010 Report Share Posted April 1, 2010 FUCKK thank god theres some smart people in the world!! i say that equation and my mind went BLANK!! Quote "yes... it will play like that all day!" Link to comment Share on other sites More sharing options...
