One of my fav speakers. My C+s loved them, and they are arguably the perfect speaker for any stock/modded Marshall. Pushed they give a higher powered greenback vibe. Now, there were a bunch of different cones for them but I've probably had 5 cabs with them(currently have a 1979 65 cab) and the only difference is some were brighter than others. They all had the same mids/lows. The lows are not as tight as a V30 but they aren't loose. When you put volume to them they really wake up and shine; and sound good low as well.
Your amps will dig them Imo.
