In that space, PJ, I'd be more worried about the depth available. You really need 35cm from front baffle to rear of the cables. Maybe you could drop off 3-4cm if you bought a 90degree IEC power lead for each.
I could pack out all of the units with 2x2, giving me an extra 5cm. That said, the WHFSV review reckons the speakers are 26 cm deep. Do I really need another 9cm for a IEC connector?
Well, you need the room of the connector plus some grace for the cable to flex. Also, you need some room for the other cables. You might be able to squash it all in more.
