combining 6ohm and 8ohm

Setting it up for an 8ohm load and feeding it 6 is not the same as setting it up for 6 ohms and feeding it 8. When it comes to speaker impedence, higher than rated is ok, lower is not.

Thanks for this tidbit. So a buddy of mine has four in-ceiling speakers that he "inherited" in his new room he is renting, but he has no clue or way of finding out if they are 6 ohms or 8 ohms. He knows for sure they are not 4 ohms, because a DVD player/receiver with 4 ohm capability shut itself off within hours of plugging them in.

So he got a new higher end Sony receiver, so in order to hedge himself, he would need to set the receiver for a 6 ohm load, because you would not want to set the receiver for an 8 ohm load and feed the speakers an 8 ohm load if in fact the speakers are 6 ohm????????????

Conversely it is OK to have your receiver set at 6 ohm and feed the 8 ohm speaker a 6 ohm load?? Do I have this right?? Would 8 ohm impedance capable speakers depreciate in performance quality at all in this scenario if your receiver setting is for 6 ohm?

Thanks
