I have a question:
what happens when you connect a 100W Head to a 1x12 cab that has one celesion V30 (60W)? Will it break or distort?
If you dime the volume control and wail away? Yep, the voice coil will fail soon enough. If you keep the volume down below 1/2 the speaker should be fine.

^ I wouldn't chance it running 1/2 volume, your most likely putting out the full 100 watts by 1/2 way on the master.

Yes it will work, but I'd keep the volume down alot. As soon as you hear the speaker start distorting turn the volume down. And I would not use that configuration for too long or you will destroy the speaker
