So these speakers seem to model pretty well in WinISD @ 7cubic ft internal volume, tuned to 45Hz. http://www.parts-express.com/pe/showdetl.cfm?partnumber=295-034 Looking for a project (AKA something to keep me busy) that wont break the bank, plus I'd like to scale down from my 8x10. Would like to do a pretty simple 2x15: 1/2" ply, 3/4" baffle, couple ports, handles and some casters, sized height wise between a typical 410 and 810. Is this speaker gonna fit the bill? Any other cheap speaker recommendations? Not a master of WinISD, but I think I get the gist of what to look for..
