I have an Onkyo AV unit with my xbox, wii etc running through it.

I laid my hands to a pair of floor standing speaker which are 8 ohms, I've looked up the details on my AV unit and it says it runs at 6 ohms.

Now I am no expert at this and not really sure what it means, just wondering if it will harm the AV unit or the speakers??

Any ideas please?


TIA

Optimum performance is achieved with matched impedance (ohms), but as long as you have a higher impedance value on the speakers then you'll not harm the amp. Never run speakers with a lower impedance than the amp.

Not an issue, the ohms figure is only a very basic indicator anyway as the impedance will vary with frequency quite a bit.

Anyway, the source's you are using a far from hifi anyway

Thanks for the advice guys!!   

I will look for 6 ohm speakers in the new year, but at least in the meantime I know now that I won't be doing any harm!!
