Would a heavy hand on the volume blow my 845s

Went a little crazy with Stanley Clark. Pushed my SET amp as hard as I ever had. Just grooving with some ear splitting/heart thumping bass. Preamp read 90 (digital volume read-out goes to 100) and I think I could have pushed even more. I backed off because I was nervous I'd blow the 845s, but I was itching to hear just what 101db speakers could do with my amp maxed out. Is this a legitimate worry? What would happen if I pushed that baby right to the top? Not a habbit, but sometimes the music calls for some very serious spls. thanks in advance, warren
