Quick question, If tuned to 32, does it make the box bigger? my box(same sub) is much bigger than that? 29x29.5x16.5?

I haven't really done any designing except on online calcs, and am no expert, but I would think every time you raised the tuning freq, that you would slightly lower the gross size of the box(considering all other variables stay the same. I would think this would always happen due to a smaller port volume, though I can not say for 100% //content.invisioncic.com/y282845/emoticons/uhoh.gif.c07307dd22ee7e63e22fc8e9c614d1fd.gif

its 4 cubic feet net, which means air space only. Not counting the subs displacement, not the port displacement, and not the wood.
