Sony STR-DN1080 ohms question

[stonesfanmk]

My receiver shuts down at higher (not super loud) volumes. Receiver recommends 6 ohm speakers. My 2 Elac floor speakers and 2 Elac bookshelf speakers are all 6 ohm. I also have a powered Klipsch subwoofer which I understand does not have an ohms rating. However, my Elac center speaker is 4 ohms - would this speaker cause the shut down?
Thanks for any input.

No, not as far as I am aware
