In a medium size room, sitting 3 to 4 meter from them and listening to not higher than reference level you should be fine. I think the A3060 is such a nice AVR that it deserves better speakers. A pair of KEF R900 will be great but even the budget price R500 will be an upgrade to the RF-7II. In fact, I think even the Q900 could be a good alternative to the RF-7II.
