Curious as to the difference in sound. I must be more that just power handling / loudness? I play mostly in a worship environment but more straight on rock, and I think we end of with a "country rock" groove a lot of the time. I don't totally need the output of a 410, except in those situation where I'm in a larger room, with a drummer. I don't alway play with a drummer, so in those situations if it's too much I would like to lower the levels or I could just use a 112 cab but I am more looking for a "do it all" cab. So, Neo vs Kappa, does the Kappa have all out lower bottom end, like rattle stuff, etc? What is the advantage (if any) of hauling around the extra weight?
