[QUOTE="ssj2xxgotenxx, post: 1648859, member: 550372"] Well springbreak is finally here, and I've decided to use my free time to build my box for my xxx. I'm pretty much using Moe Lester's plans for 2.1 CuFt @ 28hz, but I plan on adding a little flair. If you guys would be so kind to check my plans I'd greatly appreciate it. Box Plans: I plan on adding a single brace spaced throughout the box [IMG]http://i50.photobucket.com/albums/f340/ssj2xxgotenxx/boxplans.jpg[/IMG] Here's the math for the brace at 1" thickness.... Displacement of entire "solid" brace is LxWxH: (8.75)x(.75)x(13.5) Divided by 1728 = .051 CuFt Displacement of "Hollow" part of brace is LxWxH: (6.75)x(.75)x(11.5) Divided by 1728 = .033 CuFt By taking the displacement of the entire brace and subtracting the hollow piece's displacement I get a net displacement of .009 Cuft, and since I'm using two I have a total displacement of .018 Cuft. [2.31] total box volume - [.018] Brace - [.19] Driver displacement = 2.102 CuFt... Perfection =D plus room to spare for triangular corner bracing =D [/QUOTE]
