I will be having small church gatherings in my house in about a month and started thinking what I need to equip it. We will probably will be having this on a monthly basis.

I will have
-one PSR2000 keyboard
-Yamaha electronic drum pads
-maybe a bass guitar
-electric guitar
-another keyboard
-5 mics

Is it too ambitious to run it all to the cheap Logitech Z-2200 speakers ?

Our home has medium size living room, probably about 600 sq feet or so. There will be about 60 people total

What else do I need ? A powered mixer ?

I have not purchased anything yet: any other recs ?

Thanks,
Han
