XtremeLoud Posted July 12, 2011 Report Share Posted July 12, 2011 Hello everyone! It's wonderful to be a new member to this cool forum. I have a little situation here I am trying to figure out what my enclosure is tuned to, its a dual 12" enclosure. The dimensions of the box are 14.5"H x 30.5"W (29" if we subract a 3/4" lip on the sides) and the depth is 16" And the dimensions of the slot vent are 13"H and the port is L shape and the overall length is 18.75". The width is pretty odd, it is only one slot with a divider down the middle that separates the chambers it looks something like this | | | so the overall width is 2.5" but if we separate the chambers each measures 7/8" and the last 3/4" can be accounted for by the divider the slot has. Any help is greatly appreciated. Quote Link to comment Share on other sites More sharing options...

RooTxBeeR Posted July 12, 2011 Report Share Posted July 12, 2011 Ya, I dont really understand much, but I got around the same as ^^^. would help to on woofer displacement which would bring tuning up.

727Designs Posted July 14, 2011 Report Share Posted July 14, 2011 (edited) Thanks guys its much appreciated so I should be fine with my SSF at 35hz?? You need to figure in sub displacement to get the exact final tuning, then stay 4-5hz below that for the SSF.

Torres Posted July 14, 2011 Report Share Posted July 14, 2011 (edited) whats the formula to calculate this?? some people use different formulas, but this is a commonly used one Thanks guys its much appreciated so I should be fine with my SSF at 35hz?? You need to figure in sub displacement to get the exact final tuning, then stay 4-5hz below that for the SSF. sub displacements would barely change the tuning, and given that his are shallow mounts it might change a couple tenths at most, if that even Edited July 14, 2011 by Torres Quote Link to comment Share on other sites More sharing options...
