wow ur gonna need more than 3/4 for a 10 cube box... the biggest panels should be doubled up and the box should have either 2x4's or threaded rod for bracing

Now you can post them yourself! All you have to do is locate them on your harddrive!

i know on all my boxes i use 3/4 mdf and then double every part of it to,because teh flex is a bad thing.

i just got back from home depot. I bought two sheets of MDF for the box i will build for my 15 L7s. i was planning on using 3/4" MDF, but i accidentally got 5/8". what will be the difference? should i return it? i know it will be lighter but how much more will it flex? it is only a 1/8" difference but whould i worry?

How many drivers are you using specifically? 10.9 cubes is alot of airspace.

You're going to need at least 3/4" MDF. Remember, you say that 5/8 is just 1/8 smaller than 3/4, but it's also just 1/8 larger than .5". You should really look into 1" with that size enclosure, or just double up the critical panels (the baffles really), and brace the rest if you decide to just use 3/4. 5/8" just will not suffice for anything of this magnitude, you'll see more flexing than Muscle Beach.

5/8 ought to be okay. just be careful with your cuts. get everything straight, use plenty of glue and make some bracing. it'll be fine

well i returned it to get the 3/4". but i've never really looked into bracing, but i am gonna double baffle this ****. will to much flexing hurt my subs or make the box explode?

jman who the fu(k is that in your avavtar?

That isn't true in the least. Straight cuts and using lots of glue are not going to cut down on panel flexing. He needs thicker wood and more bracing.

It won't hurt your subs, but if you don't build it properly, then it could potentially explode. Remember, a ported box at Fb can have higher pressure internally than a sealed box. You're going to want to brace it up well. If nothing else, you'll get some panel resonance which is one of the nastiest sounds in all of box building right behind port chuffling/port noise. It can also take away from your sound output (not always), so bracing is almost always to your benefit.
