Help on building a box

The recommended sealed enclosure volume for each one of your subs is between .875-1.25 cu.ft.  I've made boxes for Sony's, Rockford Fostgate, and Pioneer subs and they always have a specific volume not a range.  I guess if you want your bass to be tighter you can make it in the low end of the range.

Remeber to subtract the subwoore displacement form your box volume calculations.  This one is 0.15 cu. ft.

You can make it using general algebra.  Remember to subtract the wall thickness.  Buy some 3/4 in MDF wood, make straight cuts so you will not have to fill in the voids on the joints.  Separate the two speakers with a piece of wood inbetween; that's the only bracing I use in my sealed boxes but some extra bracing is recommended.  Don't make small holes to run the wire trough without sealing it; buy the terminal connector at Radio Shack or and audio store.
