I'm on a bit of a search for the best 2x12 to match to my Marshalls. I have a 2061x head (20w) and a 2204 (50W). I'm curious to hear what you guys are running, and speaker choices as well. If you're running an open back cab, did you choose that after trying a closed back or vice versa? I expect that a closed back with greenbacks would be a popular choice, but am interested in what everyone likes and why.
