Don't bother with with them, there a P.O.S. from reports in the field, yea they say there geared for Pro Sound which is B.S., that is if you're doing shows no bigger than a coffee house. And at $4,000 a piece there not worth it, Don't fall into the Bose Marketing B.S. trap. Remember this line:Friends don't let Friends buy Bose!!!
That is if they know anything about audio.
