Hey guys... Anyone try a MC412A cab yet? I just ordered one and am having a hard time finding any info on these. What is the Celestion Platform 50 speaker? Celestion doesn't even have anything on their site about them. What are the cabs made from? Birch plywood ot particle board? Sucks being one of the first to buy something when the manufacturer won't give you specifics! Any info would greatly be appreciated! Thanks!
