I'm a long time user of SWR 410 cabs (more than 10 years). Compared to many other cabs, I feel the SWR have something special. Clean, massive lows, super punch. The closest I had was the Ampeg 610 HLF.
It's still a bit heavy, but to me, one of the best 410 ever. Compared to the Mesa 410 PowerHouse, I felt the PH was a bit too aggressive. While the SWR was as efficient, but cleaner and smoother.
