alpine Posted March 21, 2007 Report Share Posted March 21, 2007 (edited) OK so when i built my box it was tunned to 33Hz so i added,not thinking it would hurt the tunning, i put 2 2x4s going up and down and 1 2x4 going from front to back. i later found out it changed it to 40Hz i was mad.So SPLGEO told me i could shorten the length of the port by adding a piece of mdf wood to the sides of the ports to the back until the bass was low enough.I cant tell whats good so can somebody please tell me how much shorter i will need to shorten the ports by adding 3/4 mdf pieces. here is what i built. i am going to put the origanal box design up. this is double baffled also.Please help! THANKS. Edited March 21, 2007 by alpine Quote BANNED LIKE A MOTHAFUCKA IM BANNED BECAUSE IM A FUCKIN FUCKTARD Link to comment Share on other sites More sharing options...

andym85 Posted March 21, 2007 Report Share Posted March 21, 2007 if you wanna tune lower you shouldnt be making your port shorter, it needs to be longer Quote i likes me some audio stuff... Link to comment Share on other sites More sharing options...
alpine Posted March 21, 2007 Author Report Share Posted March 21, 2007 well thats the problem the guy who designed the box said to add 2" to each end of the port but if i do that my subs wont fit, her is a pic, where the port turns if i add 2 " the sub wont fit Quote BANNED LIKE A MOTHAFUCKA IM BANNED BECAUSE IM A FUCKIN FUCKTARD Link to comment Share on other sites More sharing options...
andym85 Posted March 22, 2007 Report Share Posted March 22, 2007 have you heard it play yet? you may like 40hz, i wouldnt, but some do. but it kinda sounds like your screwed. you could take the 2x4s out and brace from the outside....by kinda wrapping the box in 2x4's...but then your box might not fit in your car...sounds like you are either gonna have to live with it or rebuild it...

majorpayne Posted March 22, 2007 Report Share Posted March 22, 2007 Just invert the back two subs after you lengthen the port Quote Link to comment Share on other sites More sharing options...
