I'm thinking about retiring my SWR cabs pretty soon, and was interested in the 73 lbs. Avatar B412 NEO. I play quite loud and actually like the 29" x 29" guitar cab shape. For heads, I have an Ashdown ABM 500 Evo III and a Music Man HD150 tube. I'm wanting to use the MM head a bit more, so I need some pretty efficient drivers. There doesn't seem to be much out there on these. I also looked at an Ashdown VS412, but wasn't sold on the red cloth grille.
