Since getting my KN7 in October, I have played 2/3 gigs every week - and only once have I taken any additional amplification and that was for a Large Country Club (Formerly a Miners Welfare)
One of my regular venues is a medium sized pub, where I back singers and they are all quite happy with the mic straight out of the KN7. It's also very easy to balance the volume between singer and keyboard, and even adjust whilst performing.
As for the 'spread' of sound, I think it helps that the speakers are facing up rather than out.
I would certainly recommend that you give it a try - I think you'll be surprised at the result.
P.S. Don't for get the old saying - Turn up the Volume as more Volume is drunk
