Still, don't know for sure, because I haven't had any of the gear you mentioned, but some speakers have a cut out type of protection device in them, too. However, the ones that I've seen need to be manually reset once they've tripped. Check the owner's manual. I also think it is odd that you get similar volume levels from 30w amp as with a 450w amp! However, some speaker protection circuits operate based on a certain level of distortion they detect in the input. This may have something to do with it.You need to talk to Stehno, he has 10T's with a McCormack. He is knowledgeable and should be able to help you out.
