does anyone have the hartke Vx410 or Vx115? I was thinking about getting those bass cabinets , however I am not sure if they are good or not. Also, Would I be able to run a 400 watt head through them? because The Vx410 handles 400w and the Vx115 handles 300w. would this be underpowering the speakers, an if so, does that matter.
