Choosing small bookshelf speakers

Hello, I need an advice with choosing speakers.

I have AV Receiver Denon 1802, rated 80W with 8ohm per channel, it accepts speakers with impedance from 6 ohms.
I will use them for music and movies, 50:50 and will buy 5.0/5.1 system. I will maybe update receiver too later
Room is small (2m x 3.4m)

Because I am limited in size of speakers, they have to be no more then 20cm in depth, or depth up to 25-26cm but limited to 17-18cm in width. And because speakers will be 1cm from wall, I need front bassreflex, or closed speakers

After searching I found these speakers on market. All are from different sellers so it is not possible to compare them, and only QAcoustics is possible to borrow for home listening.

Variant A
20cm less in depth
- Q Acoustics 2010, 140€/pair, 6ohm
- Q Acoustics 2010i, 180€/pair, 6ohm

Variant B
longer in depth but width is less then 17cm
- Tannoy Mercury V1, 200€/pair, 8ohm
- KEF C3, 240€/pair, 8ohm

I would buy Q Accoustics because I found very good reviews on them. But I am afraid if I buy newer AV Recevier, I will be limited to only ones that support 6ohm speakers.

Which one would you recommend me?
I was personally decided for Tannoy but they will be very close to fit. I found Q Accoustics later but they are closed and 6 ohms.

yes, I know But height can be up to 45cm, and more if I set shelf with speakers lower. problem is combination of width and depth..

I will borrow 2010's today or on Monday and if it will be good for me and my room, I will stick with QA 2000 series So no combination of impedation. surround (and maybe front height) will be 2010 too, center from the same series.

Funny thing is that I have space to use floorstanding speakers for surround which would be weird.

Paradigms are a "little" out of my budget


KEFs didn't had very good review on whathifi :/ http://www.whathifi.com/Review/KEF-C3/
Seller just mentioned that they have KEFs too - the same seller which I asked about Tannoys. It is hard to decide without demo all of them

FYI, DALI Concept 1 are the biggest candidate now. They fit perfectly I will demo them before buy but seems they are the best for me (with my size limitations)
