yeah the making a box thing got a lil addicting so i might try that!!! my girlfriend bought the sundown sax-125.2 and the 12 dcon s4 so im gonna be building a couple more boxes!!! and when you say smaller what size do you recommend on the box??? Thanks to everyone for the feed back!!! You don't have to go smaller, just saying you can. 2.5 is on the larger side for the Dcon, though not too large. Just mentioned smaller if you wanted to save space. If need be, you could go as small as 1.75 cubes, but you don't have to. But yes, building enclosures is fun, and there is that feeling of accomplishing something made from your own hands having more value to you.
