Box Indestructable

[korey_hofer]

thats explains the stiffness of materials. not the sound of materials as your woofas are beatin against it. birch sounds hollow where as mdf sounds a little bit deeper, i guess depends on the thickness. i dont use anything under 1" mdf so.......

if your box sounds hollow you have more problems than the material it's made out of

you need to make the box dead and mdf is denser so it becomes dead easier but trust me none of my boxes sound hollow and I have mdf and birch boxes right now hell I even have a 1.25" sided sealed box made from plywood and it is 90% dead

2 layers mdf

you will have a much stronger box if you use birch and not mdf

I will never use mdf again

double layer where you can

resin and matting (resin alone does not make box stronger)

then test it if it has any flex use wooden dowels to brace it

I havn't needed bracing in 4 years because of using birch and double layers

I use Birch and will never go back to MDF

Interlock all the joints like in the pic. Brace and Resin the inside and rhinoline the outside. You would be good to go.

they do make HDF high density fiberboard.

wenn i wasent talking about my box sounding hollow. i am speaking from hearing someone elses birch box from outside the vehicle.

[korey_hofer]

exactly I have never seen any one who has used both say oh I will never use birch again it's always the other way

screws hold much better

you get actual saw dust not the dust mdf gives off which it very fine and can screw up your lungs

I plan to do a test with different types of wood as soon as I can get a t lab and rta to show exact differences

bottomline its all personal preference. im not knocking either material.

I have heard of hdf so how does that compare to the two?

idk ut here is your explanation.

Hardboard, also called high-density fiberboard, is a type of fiberboard, which is an engineered wood product. It is similar to particle board and medium-density fiberboard, but is denser and much stronger and harder because it is made out of exploded wood fibers that have been highly compressed. Consequently, the density of hardboard is 31 lbs. or more per cubic foot (500 kg/m³)[1] and is usually about 50-65 lbs. per cubic foot (800-1040 kg/m³). It differs from particle board in that the bonding of the wood fibers requires no additional materials,[2] although resin is often added. Unlike particle board, it will not split or crack. It is used in construction and furniture. Hardboard is produced in either a wet or dry process. The wet process leaves only one smooth side and dry processed hardboard is smooth on both sides.

well the last time I used hdf I was 12 but I hated it chipped very easily and would not hold a screw to save it's life I don't recommend it at all but that was a long time ago

HDF is hard to find and you will pay for it.... i have used both birch mdf maple oak

i like the plywood but to me it seems i have to double up everything to make it as strong as 1" or 1.5" mdf i like how light plywood is but its harder to work with in some areas.

still stuck in between mdf double stacked and birch.
