Glue together with wood glue, screws to get good pressure on the joints. Seal with silicone adhesive sealant. Most people use a Jigsaw to cut the holes, if you have a plunge router you can pick up a Jasper circle cutting jig from Parts Express.

ok thats kinda what i figured. but i wanted to make sure as this will be my first REAL box build. i want to make sure its sealed up tight. any particular type of silicone adhesive sealant work better than another? and yea i dont have a plunger router, but im gonna see if a friend has one.

any good sealant will work, believe it or not mdf is not air tight, you can use a shop vac and **** air thru a piece of 3/4 or even 2 stacked up, I like to give the inside of the box a coat of fiberglass resin, that makes it pretty air tight.
