Guess I'm the one that gets to burst ya'lls bubble. That's not how concert sound works folks. You might have been hearing a line from the preamp if you're lucky, either that or one straight from the bass with no Eden gear in the chain at all. Either way, it would've been further eq'd, processed, compressed to sit right in the front-of-house speakers. If it was exceptional tone, you were likely hearing a good sound engineer at his craft.
Not to dis'. A WT800 and 410xlt's were the got-to backline rig around here at one time. Never had an issue getting good sound out of them, rock or otherwise.
