And always counter sink your screw holes so you don't split the wood. You will want to hold the subwoofer enclosure together with a combination So remember that both wall thickness AND bracing increase the rigidity of the enclosure. It's often more effective to brace the enclosure than to double up the wall thickness. Enclosure wall thickness adds rigidity but so does bracing. So if you have a woofer with a small cone area, only a small amount of power going to the woofer and a small enclosure than you will not need as rigid an enclosure as if you had a large woofer, lots of power and a large enclosure. Keep in mind the pressure inside the enclosure is what determines the rigidity the enclosure needs. Well braced 3/4' should be sufficient for nearly any enclosure. One inch MDF is available but can be hard to find.

Better too thick (which adds rigidity) than too thin. You can use thicker wood and the only real disadvantage is the weight it will add. Generally you can get away with 1/2' for 8' woofers and 5/8' for 10' woofers but anything larger should probably use 3/4' or 1'. The larger your enclosure and the more power your woofers will receive the thicker the wood you will need to use. Expect to pay about $30 for a 3/4' sheet (4' Marine grade plywood is also a popular option with some builders. Not available, a high grade particle board.
