Same here, I also need the dimensions for a sealed box for my 12" Infinity Reference 1240w. It requires a internal volume of 1.25 ft³ for a sealed box, but I don't know what would be the optimal dimensions for it or what a typical dimension would be. I'm completely new to building a box and this would be my first one. Can anyone help us out? Thanks.

well read up on some boxbuilding tutorials the dimensions are completely based on the space u have, just multiply the internal dimension u would like to use (in inches) and divide by 1728 (12 inches cubed (12^3)) and that will give u cubic feet. hope it helps, and congrats to me on 300 posts!!!!!!!!!!!!!

Thanks. Can a box with different dimensions but with the same volume affect the way it sounds? I was also reading up the "Golden Ratio Formula" on the box building tutorials at SoundDomain's forum (http://forum.sounddomain.com/forum/ultimatebb.cgi?ubb=get_topic;f=11;t=069744), and was wondering if it's a good idea to use that ratio formula.
