MDF or HDF?

[Kevex]

I'm trying to figure out what everyone refers to as mdf? From what I see I thought that what everyone means is the particle board stuff that looks like sawdust glued together. What I want to use though is I suppose the real mdf, its a darked brown than the other stuff and heavier,more dense,doesn;t look like sawdust. Would there be a difference?

MDF = medium density fiberboard
HDF = High density fiberboard

MDP is medium density particle board
and so on
Use MDF for sub enclosures, I would use at least 3/4" for most applications.

i believe the rule for boxes is the more dense the better...the most common used is MDF
not sure though

EliteConcept is right... Although I have never seen HDF anywhere, if you can find it, use it! My box is 3/4" MDF and that is sufficient.
