I used to use Two Nano 300 units but after a while it didn't give me the PUNCH I needed for many of my larger venues, ....now since I switched to the Yamaha DXR 8's tops with a EV ZXA1 Sub it's a beautiful thing on stage now OMG the sound difference is amazing using my S950 or if I'm DJ'ing, The DXr's really let your vocals soar and cut thru the mix also wow!. And I still have so many setup options for smaller gigs too, 1 speaker, 2 speaker all all three!! .
