You definitely have high demands to the PA you‘re using, if even the DBR10 don‘t meet your expectations (which is ok of course).
Regarding the Bose S1 Pro, which you didn‘t like, I think a pair of them would be very nice for my needs (church and sometimes small private parties), but just not for a price of 1,150 Euros.
I am thinking about buying a HK Nano 600 again, now available for 780€ in Germany.
