What are the best sounding single cabinets out there? Is there a great sounding closed back cabinet, or are the open back or ported designs best. Rock music is my mainstay, but I like to stray into other kinds of music too. The head will be a Stephenson 30. Output tubes are two EL84's and two of any kind of octals that you can dream of, and any of the tubes can be switched in or out. The amp arrives with two 6V6 octals, but I wouldn't be surprised that I soon change these for EL34's. I want a single twelve cabinet since I am 53, and am thinking into the future of saving my back, otherwise I would go for a 2x12, but that'l be getting heavy in the near future. I think like the idea of the more inefficient speakers such as greenbacks. So what do you say?
