Indeed - I love the RCF Evox 8s that I have, just two boxes, no extra poles or anything, turn up and plonk them down, connect them up to the mixer, or if you got a JMix8, which is basic but functional, one to the other, plug the power in, jobs done, no poles etc. Plenty loud for a pub or basic outdoor stuff (including the bass and bass drum going through them).
If you haven't got the one with the mixer in, get a basic digital mixer which are really cheap now, a XR18 (or even smaller), or even a flow 8. But if there are 6 of you and some instruments, something like an XR18 would give you a microphone each, all the instrument, then speakers to out, and 6 outputs to IEMs, or monitors, or the cheap P-16 personal IEM things (which are fantastic) for an individual mix.
That is what I have done a few hundred gigs on and no problems (actually the evoxs, probably still under 100 gigs, but the mixer and everyhing way over).
