Question about a set up


Hi,
As I have little knowledge around this topic I would like to ask a question and  seek advice.

The system that I am about to buy is made out of these 3 components: 

-Onkyo TX-NR 6050 receiver
-KEF - Q Series 6.5" 2-way Bookshelf speakers (pair)
-Audio Technica ATLP60 XBT Bluetooth stereo turn table


1) the receiver model and brand I wrote would work fine with those speakers?

2) the turntable would also run with the receiver I hope. is this fine ?

 

3) what kind of subwoofer would you recommend that works well with this receiver and speakers?   

I checked the nearby stores where I live and these are the available products it seems I can choose from that fits my budget:

Polk Audio PSW108 10" Powered Subwoofer
Polk Audio PSW10 10" Powered Subwoofer, 100W

Polk Audio - React 7" Wireless Subwoofer

Klipsch - Reference Series 10" 150W


Thank you all for your recommendation
Cheers

@mesch  I ended up sticking w/ the KEF's.  I want / wanted to "listen" to something before I invest money into some speakers, and unfortunately BB carries (in my price range) only a few brands...Out of all , the KEF's made the most sense.  Tomorrow i will pick up the Yamaha AVR, KEF's and the other TT that you guys suggested.  

Also, thank you for the cable recommendations too. Once all is set , i will perhaps take a picture and share my opinion w/ the final outcome :-)
