Particle Board

[99concorde 10+ year member]

Is 3/4 inch particle board as good as mdf. at lowes all they had was like birch mdf and it was 35dollars for an eight by four sheet. the particle board was almost the same and cost 9 dollars for the same sheet.

No. Use MDF.

No. Use MDF.

Agreed. My first box was out of PB...no comparison

crap so if i already bought and cut it it wont work at all. why is it not as good.

It's not as sturdy and has a tendency to flex....I suppose if you're running a small amount of power you can get away with it, but if it's anything significant, MDF is the way to go.

If the box flexes and you still don't want to buy MDF, you could try soaking the box in fiberglass resin....

well im going to put two re8 in it. with about two hundred apiece if the porousness(sp)is going to be a problem i could use a sealer of some sort. i really just wanted to see what the eights sound like but since it looks like i blew my twelves i will have to run the eights for a little while.

With a properly built box using the particle board, you should be ok....

yeah i think it will be alright, i will probably use some sort of sealer for the inside. how much different will the eights sound than my twelves.

It all depends on what kind of box and the quality of the box. If you had twelves then you had more cone area thus the twelves should be louder if put in the same type of box. but if the twelves were in a sealed and your now going with a ported for the 8's then you might see a slight gain or a large gain... it all depends on the box. But if your twelves were in a sealed and the eight's in a sealed then you will probably have a slight decrease in volume.

if you brush a nice coat of resin on that stuff, it'll do just fine. glue it, screw it and cover it inside and out with fiberglass resin and it'll be solid. You probably want to double baffle the face too.

i tried to make a box out of that stuff a long time ago, and i wasn't too pleased with the results. 1" masonite mdf is my favorite building material at the moment.

what is double baffel. how hard would that be to do.

 

[LoneRanger 10+ year member]

double baffle means two boards instead of one

 

[99concorde 10+ year member]

So instead of of 3/4 inch board make two. wont that be really thick. maybe i dont understand.

i think double baffle means, like after u build ur box, u put another board on each side of the box. it reduces the flexing. it will give u an inch and a half thickness. that could help ya out some.
