Hi, total newbie here.


I'm replacing my Pioneer HTIB with a mid-price Yamaha 7.1 receiver and a low-end Yamaha 5.1 speaker set. I'd like to re-purpose the front Pioneer speakers to be my "Zone B" speakers on the Yamaha.


But the label on back of the speakers has this warning: "Connection to any other amplifier [than the one they came with] may result in malfunction or fire."



Seriously?!? Or is that just CYA legalese?


The Pioneer speaker system is model S-HTD520. The speakers are labeled 115W & 8 ohms. The Yamaha receiver is advertised at 115W, but the specs say 110W per channel. And the new speakers are 6 ohms, so I guess I'll be changing the setting on the amp to that (or shouldn't I?)


So is there really a risk in connecting the Pioneer speakers to the Yamaha amp? I promise not to hold anyone here responsible if they burst into flames.



Thanks,

joelk

No. It's a stupid lawyer CYA clause they stuck in your manual. You'll be just fine using your old speakers with your new AVR.

Whew -- thanks!


Will it be OK to mix the old 8 ohms speakers with the new 6 ohms ones? And should I change the amp setting to 6 ohms, which all the speakers except the Zone B will be?

It's always best to use the lowest impedance setting on the amplifier, because there are very few speakers that don't have a 4 ohm or 5 ohm impedance at some frequencies.


The impedance of any speaker is different at different frequencies, and the number the speaker manufacturer gives as the NOMINAL impedance is a very rough approximation of the AVERAGE for that speaker over the audio range of frequencies.


If 6 ohms is the lowest setting available, be sure to use it.


It is possible to set a speaker on fire, but only by exceeding its power limit by a huge amount and causing it to short out from overheating. It is very rare for that to happen.
