Hi
I don't know about your aesthetics sensibilities or proclivities but these are big and IMO ugly speakers that can overwhelm a living room. I again suggest you to have a harder look at the JBL 708p. They don't seem to be as well regarded here (ASR) as Genelec but they hold their own and are in many respects as good while costing in the USA at least, much less.
With subwoofers they'll get you there/
My recommandations are based on my on-going experience with their lower cousin which I own: The JBL LSR308 (about $550 /pair). This system surprises me on a regular basis, in my 16 x 10 x 9.5 ft roughly ( 5 x 3.2 x 2.7 meters) room. The subs are dirt cheap Dayton Audio SUB-1500 from Parts Express and the pre/Pro is a Denon AVR-3400... Next step is 708 and a pair of SVS 1000 Pro. I'll retain a LSR 308 for center channel ...
I could write a lot more on my ongoing experience and may actually do it. I believe in most rooms , paired with good subs and appropriate DSP, if 2-channel is your game (even for MCH but DSP in MCH is not clear to me at this point so ... I defer to the experts on this). One can build around the JBL 708p a world-class audio system. in the same room surpassing these could require expenditure in the >$20K. The 708 correctly integrated with subwoofers could well be the best ROI for mortal audiophiles
