For clarity, I am selling so I would be all enthusiastic about them
However, I cannot think of a single reason to use a powered mixer and passive speakers these days. Newer active speakers are not super heavy and the digital desks do SO MUCH more than analogue ones ever could. Onboard compression for each channel. More FX than anyone knows what to do with. Programme a mix per song. Give everyone control over their own monitor mixes. Multitrack the gig. Huge EQ possibilities, both on channels and on each output. The list goes on and on.
For good measure, I would buy a Yamaha EAD10 to mic the drums. Expensive, but a set of drum mics will be £200 minimum, add cables, stands and a larger multicore to the mix then it starts to pay it's way. And of course there is the drummer setting up all their audio instead of sound bod doing it. Win/Win.
