@mijostyn "Do you have stadium concerts down under? If you go to one you can hear midrange/bass line sources. The sound is usually awful. I do not bother any more"
Yes, there was a concert last night at Sydney Olympic Park, Main Arena. Seats over 80,000. Could hear it from home!
We went to a Bushfire Aid concert there a couple of years ago. Queen and Adam Lambert had played the night before, and let every other gig use their sound system. We arrived early and could hear kd lang practicing hard to get her sound right. The sound during the first session was so bad overall that we found a beer garden outside and listened from a distance. Later acts must have learned something because the sound became listenable, then good. kd lang sounded brilliant and Queen finished off in their usual style with superb sound. All from the same hardware!
Queen's Brian May is an astrophysicist in his spare time. Fred Hoyle, who coined the phrase 'Big Bang' because he thought that particular origin theory was rubbish, worked out most of the nuclear reactions occurring in stars. To Fred, a star was a one-dimensional problem. Work out what happens on one line radiating from the centre and you have solved what happens on every line.
Brilliant people can sometimes be wrong. And sometimes conventional wisdom is overthrown by a single visionary, at which point everybody else becomes wrong. Newton, Einstein, Hawking: each did this/
In fact a fan is what gave him the idea.
