First time user, I am searching for the perfect speaker cabinet for small gigs. I do run tube heads (Sunn 2000s and Ampeg V4b) and I like lots of bottom end (from my speakers). I am used to using 2-15 cabinets and tried a 2-10 from Avatar but it didn't fit the bill. Most of the time we use subs in the PA so I don't need to carry a 2-15 cab any more. Any suggestions? How are the 2-12 cabs?
