+1MDF is actually the most common cabinet material for speakers and subwoofers. It's compatible with a wide variety of finishes, including paint, and is rather inert so it makes a good choice for speakers and subwoofers. When you think about the fact it's essentially sawdust and glue fused together with heat and pressure it does make you wonder about some of its properties, but the stuff seems to work well.
Just for your woodworking educationOkay. Thanks. I guess I was just a little confused when reading Jim’s review of the G25HP, where he said there were finish options in, “...black oak veneer, matte black vinyl and a high gloss 'piano' finish.” I understood what he was talking about with the black matte vinyl finish, where it is just vinyl applied directly to the MDF. But, I was assuming that the other two finishes where veneer’s with either a high gloss paint applied for piano black or a stain for the black oak. I’m only asking, since I have very little understanding of woodworking. I didn’t know that MDF could be sanded very smooth and painted directly.
Actually MDF is very smooth, and very heavy. The one of the reason many quality manufacturer use this as there prefer cabinet material.
Another material that is often use in other quality cabinets, is Birch Marine Plywood. Very heavy and very expensive, between the two. I prefer MDF for it's ease of use, if you built your cabinets.
I once ask why they do not use hard wood or other fancy materials.
The answer was very simple. Speakers and subs re-produce sound, and should not produce sound like an instrument.
Therefor MDF or Birch Marine Wood been the choices, of quality manufacturers.
Since they are very inert, and do not produce there own sound like an instrument.
