MDF vs. particleboard
 
I'm engaged in a "discussion" with a rather hardheaded individual about particleboard vs. MDF for subwoofer enclosures. He stresses there are no fundamental drawbacks to using particleboard, other than the fact that it looks like *** and is difficult to finish.

I disagree, but I need some concrete numbers or facts to back the claim up...or just any applicable evidence.

Thank you in advance!

To add to the confusion: I think multiplex is the best.
I've been told by experienced speaker builders here on the forum not to use MDF for subwoofers, certainly not in a pro environment.

Whichever suits the DIY'ers sonic taste and budget is best ;)

That and have you tried a router on particleboard? :dead:

Particle or K3 board is cheapest but weakest. Doesn't hold a screw forever and doesn't like moisture. Used it for years before MDF came along.

MDF is good sonically but doesn't like moisture and is only medium tough. Used it some.

Plywood is toughest but not as dense as MDF. Use nothing else now. IMHO easiest to work with.

I'm not sure you're going to find a concensus on this . Like Gregg says, it's up to the DIY budget.

if correctly damped and braced, i don't think that particleboard is so much worse than MDF, only screw are never sufficient with particle

also i prefer to work with particle board, i really hate this MDF dust, it don't even smell wood

so for me : if you are poor : particle board
if you are rich : Plywood

i built a sealed sub out of particleboard with a SLS 12, and it is totally inert

Engineering specs. for appleply and plywood:http://www.statesind.com/pdf/ApplePly.pdf Engineering specs . for chipboard: http://www.fpl.fs.fed.us/documnts/pdf2000/salik00a.pdf (page 5) What should be of primary concern would be the Modulus Of Elasticity. This will reflect how the materials bend and would effect cabinet construction. There is little question as to density. Lift a panel;) . If this is about the thread on SIN, yeah , the builder of those cheap boxes is way out of line.

What about OSB? I was using and keep using that and I think is better even than plywood in some circumstances, like subs.

I quite like chipboard for horns...

Look at the following waterfallplots:

Particleboard

MDF

As you can see there is not much difference between both materials.

For people interested in the test conditions, more measurements, incluiding birch ply, meranti ply and sandwichstructures (it's in Dutch however):
