HELP, Please :) Which receiver do I need?

[shlomikalfa]

Hi,

I've been looking for days now ... can't really wrap my head around the whole ohm / rms output and such, it seems like there are too many details to take into consideration.

I've ordered these speakers:
Reference 162 * 2
General Specifications
Nominal Impedance 8 Ohms
Frequency Response 49Hz –22kHz
Sensitivity 88dB
Recommended Amplifier Power 20 –150 Watts

Reference RC252
Recommended Amplifier Power 20–150 Watts
Nominal Impedance 6 Ohms
Frequency Response 58Hz–22kHz
Sensitivity 87dB

Reference SUB R12
Frequency Response 29Hz–150Hz
Amplifier Power (RMS) 300W
Amplifier Power (Peak) 600W

For my new living-room mini-cinema room
Also ordered this projector:
Optoma UHD30 True 4K UHD Gaming Projector | 16ms Response Time with Enhanced Gaming Mode | Lowest Input Lag on 4K Projector | 240Hz Refresh Rate | HDR10 & HLG

I'll use this setup JUST FOR 4K MOVIES - ONLY!

I'm missing a receiver to make sure I can actually enjoy the speakers quality to the max (or closest to it)

I was looking at - Just as an example!
Yamaha RX-V385 110 / 220v Receiver amplifier, 5.1 Channel AV Receiver 110 - 220 - 240 Volts 50 / 60 Hz
Yamaha RX-V485 110 / 220v Receiver amplifier, 5.1 Channel AV Receiver 110 - 220 - 240 Volts 50 / 60 Hz
Yamaha RX-V479 110-240 Volts Receiver 110 - 220 - 240 Volts Amplifier
Denon AVR-2312CI 220 volts home theater Receiver amplifier amp

I'd rather have a 5.1 powerful receiver then a 7.2 etc of lesser power.
price range -> cheapest possible / up to 600$

Any suggestions?
Which AVR should I buy?

Thanks for you help!!!
