3/4 " is much more solid and will resist againt flew better. It you have a bad enough sub, it will rip the 1/2 " right apart.

depending on what kind of woofer and application 1/2 inch would work fine, like a single 8 or 10 in a sealed box, with low power.....for an sq system would be fine

yeah --it generally just flexes to much, the one criteria for using it that no one mentioned was that its a small box, long sides flex a lot more than short sides, I have used it where space is tight and reenforced it will a few layers on fiberglass, it CAN be used, most find its just not worth the hassel.....it also splits a lot easier when you screw into it.

k, jut wandering cause the box i got is made up of 1/2Mdf and its for 4 12s.. w/ about 2400 watts, and i have no problems w/ it..i did build my box 1st out of 2x2s for bracin and uses liquid nails, caulk and even fiberglass on the inside along w/ many screws..

I would definetely use 3/4. first of all, you KNOW your box wont explode. and when you drill the screws in, they will go in with 3/4. if you used 1/2 in., your screws would split the wood, and you wouldnt get a good seal.

to tell ya the truth, air nailers work best, and carpenters glue does the sealing and most of the bond
