I was rushed to buy 3/4" MDF for Solo X18" and was exciting about that. In fact, I was told by other members of Sounddomain forum that using 3/4" MDF with strong braced will be fine. Unfortunately, about couple of weeks later, I've spoken with one of the Kicker Support Tech and he recommended me to get 1" MDF instead. So I went to Lowe and see if they have 1" MDF; however, none of them has it and I was disappointed.
But for some reasons, it got me thinking that you can double the layers of 3/4" MDF altogether (though it'll be 1 1/2" thick). I wonder is that okay? Good idea or bad idea?

I just did the exact same thing last week for a customer with that sub. Works perfectly well. Personally, I opened a bottle of gorilla glue and poured it onto the wood then brushed it out. Clamped the pieces together and shot some 1.5" brads with the air nailer through it. That glue will not only be partially absorbed into the wood but will expand to fill any voids and is by far the strongest wood glue I have ever used. You couldn't pry the peices apart with a crowbar if you tried.

Ah, sweet! Thanks, man. I appreciated it. I'll be sure that my friends and I will make the double layer of 3/4" altogether real tight and real good. Now that I have to go and buy more of 3/4" MDF woods.

If two 3/4 sheets are too thick for you, you could also try slapping together some 5/8 sheets. Thats if you only wanted to stay close to 1 inch thickness. It may also save a few pounds. Also, Gorilla glue is the best. Good Luck

Be careful with gorilla glue and some other polyurethane glues: They foam, and expand. Better and cheaper might be some tightbond 2. Also, you can screw it together, or throw some bricks on that bad boy.
PS: the difference between 3/4 and 1" mdf isn't all that huge. Granted, 1" is a little stiffer and stronger, but, if you're gonna brace the box up a bit, I wouldn't expect the sub to do any damage to it at all.

i always thought, twice as thick is 4x as strong...
my new box i used four layers of 1/8" mdf to make a tightly curved section of the box. extremely tough after the glue cured. would bet it's much stronger than 3/4 or 1inch with the curve taken into consideration.
