Ok so I have established that shape is nothing and volume means everything. So having access and experience to woodworking mediums, I have something crazy in mind. I want to build an angled box, but am not a math wiz and have no idea how I would calculate the volume to find the right measurements. Would it be possible to build a "box inside a box"? Lets say I need three cubic feet. Could I make a 1 X 1 X 3 downfiring rectangle box that the sub would be mounted onto. I would then secure this box in an angled cabinet of my liking. The interior box being as compact would probably not need any bracing I am assuming In essensce the sub cabinet would be enclosed by a decorative cabinet. Possible? or nay.
