Can I hijack this thread and bring it down again to a practical level?

I was just about to connect my new QS8 speakers (surrounds) to my system, only to find out that they are 6 ohms and my receiver has this ugly sign on the back that says "8 ohms minimum impedance" !!!!!

Can I connect them anyway, or is this a "showstopper"?

Thanks for any comments.
