High quality plywood (void free varieties of baltic/finnish birch, and marine grade) are significantly stiffer than MDF and therefore, make better enclosures for subwoofers. The strength and durability of ply also makes it a natural for commercial/pro applications where abuse is a way of life.
dave,
ever look into appleply ? it is realtively new, probably has the best characteristics of both baltic birch and marine grade and priced just a bit more tham the baltic. i have been contemplating a build project, when it happens i will go with the appleply. it is availale locally also but the yard i checked with will have to order it.
