Well put it this way:
Recently I went to see a band play a gig , they were using the gear provided by the venue. The first thing that struck me was the lack of bass in the mix. When I got closer to the stage I could hear a little bit of bass (very little) and it was so awful that it COULD have been in the mix but unable to carve out it's own space. No lows...a bit of mid range with no punch and that was it.
