Which PA Set should i get for Kemper and Vocals?

Have a look at the Yamaha DXR10 or DXR12 Speakers and for the Mixer at the Behringer X Air Series.

For small gigs, I would recommend the Bose L1s with B1 and Tone Match. Simple setup, takes little space, acts as your monitor, great coverage. Perfect for small venues and a simple two person band.

I use a Turbosound IP1000 and a Yamaha DXR10. We also have a cheaper powered monitor pointed back at us. We run everything through a small Yamaha mixer.

I use many P.A. systems...
when I play on my own with guitar and a microphone: a little acoustic amp, the Compact 60 (churches, vernissage, perhaps with a female singer),

the little setup for small venues is a Allen&Heath ZED 14FX mixer with two powered QSC K8, very nice and easy to transport,
for gigs for 50 to 150 people watching... don´t bother about the 8" woofer, enough bass for everything!

the biggest setup I use is a Allen&Heath QU-24 with a Fohhn Linea live active P.A. System for the whole band.

My opinion: just buy two good active speakers like the QSC or other brand, or a Bose L1 system, you´ll be very pleased:
easy to transport, good to handle, very good sound...
And a quite good little mixer... there are so many different options... just try it out!

Best regards,
Mario

With my the DUO I use https://www.thomann.de/at/allenheath_zed10fx.htm

In small venues I use as PA-Boxes https://www.thomann.de/at/behringer_b…ef=search_prv_6

In bigger venues I use https://www.thomann.de/at/rcf_art_310_a_mk_iii.htm . For me the best compromise of power, price and weight. (and no fan)
With the rock band I use one as my personal monitor and a Behringer X Air XR18 digital mixer.

Ja varreck Kaffeehaus, Grüße nach Schladming!
Mach an Ausflug zu am Gschäft und probier, dann griagst a Gespür fürn Sound und as Handling.
Grad bei Aktiv-Boxen is des wichtig...
Günstige gibt´s da zum Beispiel auch von EV, de sand a guad...
Des Nonplusultra bei kleine Aktiv-Boxerl sind immer noch de RCF TT 08, de sand schweinsteuer, aber jeden Cent wert.
Wenn i ned grad de fohhn-Anlage gekauft ghabt hätt, dann hätt i mir de gegönnt... dann sind´s grad de QSC K8 worden... da gibt´s jetzt Nachfolger, quasi MK II-Modelle, mit Digital-Menü...
naja, ausprobiern, dann segst as scho...
