I have a yamaha htr-5860 receiver that I need to hook up some speakers to. The only spare speakers I have available right now are from a samsung 5.1 htib. It is the x40 I believe. My concern is that the speakers are 3 ohm, Would it damage my receiver if I use them? I know I can safely hook up 4 ohm speakers because the receiver does have a 4 or 8 ohm setting on it.

As long as they don't dip much lower than that. Make sure the xover is set high like 100Hz or more.

they're from a HTiB so they can't be hard to drive. Shouldn't have a problem.

Mostly theyll just be used for tv and movie viewing until I can get some more appropriate speakers.

What are your opinions on new speakers? Would 6 ohm be ok or should I just get 8 ohm?

I too thought my new purchase of 5 Sony surround speakers was a bust. Every speaker was labeled 3 ohms. I checked them with an ohm meter and guess what??? They were ALL 4.5 ohms. Thank goodness. Be sure and check yours before you throw them away. I hooked them up to a 65 watt RMS receiver and really put the bass to them. They took it all without popping or clipping. Amazing what they can do with a 3 inch speaker.

Not that it really matters, but you can't measure impedance with an ohmeter.

Not that it really matters, but you can't measure impedance with an ohmeter.But you can determine the minimum impedance of the speaker, where capacitive reactance and inductive reactance cancel each other out and the impedance is purely resistive. Usually the nominal impedance is specified somewhat above the voice coil resistance.

And not that it really matters, but this thread is 2yrs old :).

Yeah, and the guy who revived it put his append at the end of a relevant, if dated, thread instead of starting a new one, and we replied. What of it? At least we had something relevant to say, unlike you.
