I am thinking of buying a Genz Benz Shuttle 9.2 and already have 2 x TC Electronic RS210 cabinets. Each one rated at 8 ohms. I was hoping to plug my new head into these but just read that the Shuttle 9.2 is rated at 500w at 8ohms and one RS210 at 8 ohms can only handle 400w. This means I could never just put it through one cabinet. Any expert opinions on this? What cabinets do you use?
