I'm looking at buying a Pioneer VSX-AX5Ai Receiver coupled with KEF Q11, Q10C, Q3, PSW2500 speakers. My viewing area is 3M x 5M with a 42" screen on the long wall. The speakers/receiver sound great in the shop, but I'm concerned that they may be too large (is this possible?) for my home. Also, I am considering changing the Q11s for Q7s and the Q3s for Q1s. It's about 12% saving and will bring me within my budget (slightly outside now), but wonder if I'll regret it later. Any suggestions/comments would be helpful.
