AP Zoutes Posted October 13, 2006 Report Share Posted October 13, 2006 so this is what I came up with before dispalcement your volume is 36.83 ft3 = 1042.9 liters I assumed a total sub displacement of .7ft3 = 19.8 liters I also suggest alot of internal bracing with 2x4's displacment = 2.0 ft3 = 56.6 liters which leaves 34.13 ft3 = 966.5 liters for your port 203mm wide x 856 mm tall x 297mm deep =29.76 hz after port displacement you have a volume of 32.31 ft3 or 914.9 l This is a big ass box If you want different tuning let me know Link to comment Share on other sites More sharing options...
AP Zoutes Posted October 13, 2006 Report Share Posted October 13, 2006 btw the lowest you can tune this is 29.76 hz. (297 mm deep) any longer then that and the hump gets in the way. you want the port to end at least 203mm before the hump. but you can go higher Link to comment Share on other sites More sharing options...
AP Zoutes Posted October 13, 2006 Report Share Posted October 13, 2006 the port walls will basically just go from the internal top to bottom. this is still a small port but is the biggest possible with the baffle area left after the subs are installed. any smaller and you will get port noise.

RichardXTC Posted October 13, 2006 Author Report Share Posted October 13, 2006 btw the lowest you can tune this is 29.76 hz. (297 mm deep) but you can go higherok i dont really know alot about tunning but i know 29 is quiet low... this whole project is for bass boxing so i thought cause the song is between 50-55hz is it alright to tune that high? 2 X 15inch XTB subs1 X Solar Audio 5000dVids:<a href="http://"http://www.realmofexcursion.com/videos/XTC...dio/xtb15.1.wmv"" target="_blank">http://www.realmofexcursion.com/videos/XTC...xtb15.1.wmv</a><a href="http://"http://www.realmofexcursion.com/videos/XTC...dio/xtb15.2.wmv"" target="_blank">http://www.realmofexcursion.com/videos/XTC...xtb15.2.wmv</a> Link to comment Share on other sites More sharing options...
