May 23, 200718 yr lots of different materials can be used to make boxes baltic birch even hardwoods main advantage to MDF is cost and lack of voids in the material birch is double to triple the cost of MDF
May 23, 200718 yr Like Jim said you can build it out of anything. I've built hardwood, birch, and MDF boxes. The advantage of MDF is that a sheet only costs ~20bucks while a good piece of BB ply is ~70.
May 24, 200718 yr MDF will not come in as many grades as Birch.Birch is lighter...but more expensive. If you decide to go with Plywood, make sure you get VOIDFREE ply...that means there aren't any airpockets in the middle, which can cause rattles and buzzes.MDF wont have any voids so you don't need to worry about it.With proper bracing they will both be stiff enough...just birch will be lighter (something to think about if you're doubling up on wall thickness in a smaller car)
May 24, 200718 yr Especially considering that my poor little ported Rli8 box is near 90lbs with the driver. MDF is teh heavy.
May 25, 200718 yr How much does a full sheet weigh anyways??And I will weight my box for the vehicle.J
May 29, 200718 yr Yeah, tell my yukon about the weight of MDF My rear end looks like it's been lowered with around 400lbs of box + audio equipment in back.
