Hi
If you are considering a Powered Mixer and passive speakers, For my own experience, great sound quality, reliability and VERY light weight I recommend the Yamaha EMX, there are several models, basically the difference is how much power do you need, the smallest is the EMX 2, then EMX5 and the most powerful EMX7.
I would pair them with the Yamaha passive speakers CBR, there are also several models, those vary in woofer size and power handling....CBR 10, CBR12, CBR 15.
The Mixer and speakers combo can be positioned in several practical positions...
My 2 Cents...
Manuel
