Mattzack2, you have received a lot of advice from guys who don't seem to understand Audio Note's speaker design technology. As you undoubtedly know, Audio Note speakers are upgraded versions of Peter Snell's original designs. Snell built his K, J and E speakers out of fibreboard (not MDF) for cost reasons and also because that the current vogue in speaker design.
After offering what were virtually copies of the Snell designs for years, Peter Qvortrup of Audio Note UK decided that the speakers sound better using resonant plywood cabinets. Audio Note eventually settled on a particular thickness and grade of Baltic birchwood that they believe sounds best.
I have helped a few friends build Audio Note kit speakers, some using factory cabinets and some using home made boxes. I can tell you from experience that the home made cabinets did not sound the same as the factory cabinets. Not worse, not better, just different. My unsolicited advise is if you want your speaker to sound like Audio Note speakers, either order the cabinets pre-made from Brian or get the plans and build them as closely as possible to the specs.
If it were me, I would not bother experimenting with MDF or any other wood product. It might sound better, but (again in my experience) probably not.
