We are a two guitar, bass, and drums setup live. Our PA out front consists of two Yorkville NX550P's. I've been able to get by without putting the bass and just a little of the drums into the mix. We have to turn the bass up so loud on stage to get the bass out front that our stage volume is too loud and we really need to put the bass into the front mix and turn it down a little on stage. I know I need a sub or two, always need more gear of course, but don't have one for our next couple gigs, but I want to put some bass into our two mains. Can I get by at small and medium gigs doing this without harming the NX550P mains? Would you do it? Just don't push the volumes into the two mains too much? Thanks for any help guys...
