DNJ,
I just assumed there was a price point.
I personally use an Allen & Heath board.
When it comes to powered mixers and smaller speakers systems, until you truelly spend the big bucks there will be of course a small increase in sound quality.
Of course a $300 cabinet will not sound as good as a $500 cabinet, but all of this will also depend on where it is being used, how, what's feeding it also.
In my first post I did say one of my questions for a customer would be, what is your budget, of course it's easy to say I would get this or that, but if he can't afford it, then oh well.
I called Peavey to become a dealer and they said 10 grand for an opening order.
Not today for me anyway.
I also sell Alesis, RCF ( which is the mackie supplier for drivers )
