Hello, I have two Eden 210 XLT cabs rated at 350 watts 8 ohms. I am looking for a new head for them. My understanding is that together they can take 700 watts at 4ohms. I am looking at a head that delivers 900 watts into 4 ohms. Would this be a bad idea? Should I get something that really just delivers the perfect amount of watts for my cabs? Have some of you gone over the wattage allowed for your cabs? If so, what happened? Thanks for your input!
