3/4 MDF for corner bass traps?

I am having a hard time finding 1" MDF - what are the consequences of using 3/4 instead? I have searched the bbs, but could not find the answer...... Thanks.

If you're referring to the slat type traps, you can use 3/4" - it will flex slightly more than the thicker stuff but I doubt you'll hear a difference. If you're just putting mineral wool in corners for broadband absorption, you don't need EITHER - just the MW with a cloth cover, and any way you can to keep it standing up; doesn't need sealing or anything...
