Hey! Does anyone know?) I really need help........

I 've got a small room, about 3m * 5m, in this room I placed four RB 81 loudspeakers - 2 as fronts and 2 as rears, they powered by marants SR7002. Now i'm looking for a subwoofer to complete my system. I guess klipsch is better playing with klipsch so I look on rw10d or rw12d and can not decide what is better for me, the worst thing is that I can't find a shop to listen to them... From the one hand 10d has enough power for my room (well I hope so) and costs suitable price, on the other hand 12d handles lower frequency (24 hz) versus 10d which can play only 28 Hz....So if anybody had a chance to listen to both subs I would gladly appriciate your opinions on this matter))))) My preferences are music and games (system is connected to PC)
