Hi there! I'm interested in the GoLight 410s -- either the ported regular or the sealed Marcus Miller. This is pre-audition; but I'm expecting the MM (sealed) version to suit me a bit better. These have more punch and less low lows. Apparently the ported ones are pretty, er... _portly_ down low. I don't need huge low extension to be bouncing around a stage, interfering with the PA's subs, & the drum mic's. Now add a variable: I'd _love_ to have big casters on it. I have enough pieces to remember without adding a separate dolly. I'd like to be able to place my head and bag on the cab, and roll it all in from a parking lot. (I'd probably replace the puny SWR casters with bigger ones; but that's another issue.) But if you play through the cab on the casters, it's suspended above the ground, and you lose lows (through decoupling) anyway. Not sure the sealed MM version would need to lose more lows. So I'm wondering if I'd be happier with the regular ported GoLight 410 -- its substantial lows mitigated by the caster's elevation. Any comments or thoughts? TIA!
