Hey guys, before you start yellin, i know i know i know, that I should really be using 3/4". But, My buddy had 2-4x12 sheets of MDF he was gonna scrap, so I took them. I was wondering if it would be safe to use this, to make small sub enclosures? I have some pretty mean subs, so i'm sure the answer is no, but if i can save some money, it'd be great. I was thinking about making 3= .5 cu.ft. sub boxes. One for each of my subs. I have MA Audio, 100D6 series subs. Let me know asap. Thanks.

Glue the two together, and clamp them down. Once dry you'll have a 1 inch 4x 12 sheet of MDF

Yes it is, for small boxes it is generally not necessary however. I have had to make boxes out of 1/2" before due to space limitations to gain necessary airspace. If you are going to make the boxes out of 1/2", go ahead, just throw some extra bracing on the inside to help keep the box from flexing.

Even though lots of people disagree, I say the 1/2" is OK. I have a 2400 watt Fosgate amp powering 2 audiobahn 12`s And I made my box out of 1/2" MDF. The trick is to use ALOT of bracing and glue-but I guess it would be easier to just buy 1", but for the free 1/2", its worth a shot, right?

I would think the two 1/2 inch would be lil stiffer. What are you running anyways? if its a couple of 8's 1/2in will do you fine.

i used less than a 4x8 sheet of mdf for my 1.3cu foot x2 box for my 12's

I'd just do like Maxst said and stack the two 1/2 inch sheets for a 1 inch thickness. I've committed some overkill before and stacked 3/4 inch mdf for some fifteens before. It turned out really tight. Otherwise if you don't want to go that route just use lots of bracing and glue. Either way it will be a little bit more work, but for the free mdf its worth it. Free usually sounds pretty good either way you do it.
