We went to see Yes and Peter Frampton at a 10,000 seat outdoor theater in Bethel NY - formerly known as Woodstock. The flown system had 10 Vertecs per side and stage mounted subs. The 8 sub cabs looked like 18s x 2
We sat near the sound engineers and there were two control boards. One board was for Frampton and the other board was for Yes and each act had a different sound engineer but, other than that, the SR system was identicle.
Anyway, Frampton's sound was very clean, had great dynamics with great clear vocals. The Yes sound was overbearing, too much bass and the vocals could not be heard or understood. One obvious issue was that the system was being driven beyond its capabilities for Yes.
So what can we conclude from this?
* Sound engineers are very important for a good experience
* Even outdoor stages (covered seating but no walls) can produce crudy results
* Vertecs are very capable if run correctly
* Boards can make a difference?
