I have wondered. Is it absolutely neccessary to run 2 pieces of mdf on the part of the enclousure where the subs mount? if you have bracing on the inside of the box wouldn't it be enough to keep the front "plate" from flexing from the subs? Besides being able to recess them whats the advantages of the second piece.

It could be used for a number of things such as: structure support, some subs way 60 lbs. and greater so something has to support that weight and stay solid to withstand the pressure among other things.

can never have enough bracing epically for those super heavy subs moving a ton of air and creating a lot of pressure in the enclosure

Bracing helps, but with heavy subs (especially with a lot of motor force) really need a double baffle to support the weight and reduce flexing of the front baffle. The subs are mounted to the baffle so if you think about the force behind a powerful subwoofer pushing and pulling the baffle it might make more sense. Obviously you can get away with a single baffle with many subs, but with the stronger ones I see it as a requirement. I'm assuming your talking about the Xcon from your other threads, and I would definitely do a double baffle for that sub. Also, I don't really think flush mounting, or "recessing" the sub counts as a double baffle, you would have three pieces in that case.

Hope this isn't confusing and makes sense lol.

It's there for structure as well as looks.

You cut one/two holes out of the mounting surface which weakens the panel like others have said.

Doubling or even tripling the mounting panel will help out mostly when the subs

are moving. With the Xmax of subs in the market today you need all the bracing you can get.

Cool thanks I figured as much and I do have a dbl baffle situation which I will be installing thanks for the replies

My enclosure does not have double baffle, but I have some bracing in it. The panels are not so long, so, there is not a lot of flex : I can't see any !

For my next enclosure, a sealed one, I will only add another piece of mdf to flush mount the sub : it looks cool, and can help with the flex (not as good as a complete second baffle, but...). I will not forget the internal bracing.

Btw my sub is an Xcon 15.

When i had a 15' BTL in a enclosure with no double baffle (i know stupid me) my box litterally looked like a monster was in it trying to escape lol.
