Denon x4000 with polk a7 and monitor 70
I have the denon x4000 that supports wides, I was wondering if the wides could be the a7 and the monitor 70. I'm not sure how matched they are and don't want to mess up the sound. Also I'd like some advice on setting up wides in a narrow room. The wides would have to be put closly to the mains, would this just defeat the purpose?
