I need help with blueprints or dimensions for a single American Bass XFL 12. I want it tuned to 32 hz and I would prefer if it could be within the dimensions of 16x16x20 and especially within 18x19x20. Thanks guys! This will complete my build once I get these and I will post results. //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
