What Material for Install?

I guy I know is going to do my ICE install, his dad is a pro carpenter and I don't doubt the quality of his work, but he's planning to use pine or other woods since he doesn't like MDF which is what I thought most people use.

Is pine ok? will is sound good?

I would not suggest pine JL however has suggestions on other types of wood. But I would recommend MDF. http://www.jlaudio.com/tutorials/boxdesign/index.html

Interesting...I always thought MDF (medium density FIBERboard) was the best thing to use as it doesn't crumble as easily, it's a lot easier to screw in to when you're near an edge, but mostly that it is less porous than HDP.  That's just what I had always been told and had read, but I've never done a side-by-side type comparison.

Personally I prefer MDF over HDP because it's a lot easier, in my opinion, to work with when you're using screws or drilling near an edge.  HDP has a tendency to flake and split when you're near the edge, even if you drill pilot holes, but MDF has never done this to me.

Only downside to using MDF is that it's messier I think, since the size of the dust particles is significantly smaller than that of HDP.  And it's definitely not a good idea to cut MDF without using a dust mask or something like that--unless you want to get a big whiff of formaldehyde

Big Purds,

I actually have my Phase 3 book out checking it over and it said that sonically, particle board IS the best to use. It says to get it in high densities. It also says to paint the insdie because it likes to absorb moisture. But it also says that yes, it is VERY difficult to find. But for high end applications, it's supposed to be the best.

For the info of everyone else...there IS one form of plywood here (which i forgot about) that IS acceptable and that's called "Baltic or Russian 12 Ply Plywood" It does say that it's hard to find though and it is quite expensive. But a plus is that it is lighter than MDF or Particle board and it's easier to work with. The optimum type of enclosure to use with it is supposed to be a pair of 8" drivers in an 1.5CUFT enclosure.

Sorry, i was bored and just started flipping through the pages....more knowledge is more power.
