I'm considering making the switch from my Hartke VX seires 4 10 over to a Avatar 4 10 because of the much higher power handling, and the optional casters. I believe both units are about the same size, though the Avatar weights about 5 pounds more. What are your opinions about the two cabs and some experience y'all have had with them. Which do you think is better? Also, does the Avatar cab have a tweeter, if so, does it work better than the Hartkes?
