Bookshelfs + Central - alternatives to KEF Q350/Q650c

Hi,

I’m looking for what i would call “medium budget” speakers for 3.1 system (subwoofer will be purchased at later date) for my small 6m x 3m x 3m “living room/bedroom” They will be powered by Onkyo TX-NR575E Receiver and used mostly for movies (Netflix etc.)

I’m not going to give you budget in $ because i live in Poland ( PLN) and prices here can be drastically different in comparison to US.

I’m currently considering KEF Q350 (current price for single speaker ->1300PLN) + Q650C but i’ve also thought about:

3x KEF LS50 (1600PLN each)

Monitor Audio Bronze 100 (awarded recently by EISA, 1200PLN each) + C150

B&W 606 (1600 PLN each) + HTM6 (2400PLN)

Which of these would be best choice in your opinion? Maybe something completely different?
Have somebody in here listened to them and can give me their impressions?
I would prefer to buy from local shops (ceneo.pl should have most of them included - you can check there if its available in Poland) but i can also purchase from Amazon.de.
