MDF is wood fibers, much better. You probably knew that, but if 6 months from now somebody runs across this, just wanted the record set straight. They are only interchangeable for low end uses. MDF is far superior.
There are two issues with MDF from a professional standpoint. Weight and durability. However the added mass can actually be a plus for home speakers.
Plywood is used for guitar tops as it resonates. You will never see an MDF acoustic guitar. Not in the hands of anybody older than ten with an ear anyway.
Lack of resonance can be good in the right place and time.
As far as particle board, I guess dummies have to have something to do. But if you have half a brain and one good ear pony up the slight extra for MDF.
There is also a high density fiberboard, the m in MDF stands for medium. High density is hard to find, but even heavier. Will kill saw blades though...like cutting stone almost.
If you find a place that builds counter tops they may have one inch MDF. Don't drop it on your foot you can lose a toe.
