My band, A Fragile Tomorrow, is just starting to make a name for itself, playing more often and bigger gigs such as playing for his Holiness the Pope in April. So I thought that it was time to upgrade my old rig to a new one. After making a few mistakes about what to get and running back and forth between stores and online sites trying to stay on a budget, I finally just bit the bullet and bought an Ampeg SVT 810E and paired it with a used Genz Benz GBE600 head (about 425watts at 4 ohms). This is my question: Am I under powering this cab? I don't understand why ampeg makes cab that can handle so much power, 800 RMS at 4 ohms, but makes two heads that are legendary for being paired together that don't come close to that (SVT-CL 300 watts at 2/4 ohms and SVT-450H 450 watts at 4 ohms)
