Well the main reason why I asked is because I am not building a box out of particle board, I just added on a second baffle to my box and the baffle I added on is made out of particle board. Instead of buying a big ass sheet of 3/4 MDF today that was like $23, I just decided to spend $6 on the particle board for my second baffle. I am just worried once I crank it up the subs will pound the hell out of it and will rip the screws right through since its such a soft wood. For a second baffle will it be fine? The rest of the box is MDF.
