ohms not showing

hey all,
i recently bought a surround package buy nuance and i am having problems with the rear speakers. they are working but my ohms tester doesn't register them, is this bad or normal. i ask the places around my place, knowledge is very limited due to isolation, and i get all different answers. from ..... it's normal for rears to not show..... to your speakers are pooched. can someone please give me answers?

thx in advance

Please do a search on nuance on this forum....

Yes, please do some research on nuance before you decide to keep them for the long run. Check out the forums or goto epinions.com. I think you will be suprised on what you will find.

unfortunatly i am stuck with these for a long time, thx for reminding me that i got suckered. now could you plz answer my question, is the fact that they don't register a bad thing.

thx

Doesnt show as in they show a open or a short?
I cant imagine that either way it would be good, but a dead short would probably trip the amp.

Remove the wires from the speakers and attach the leads from the multimeter to the speaker terminals. Make sure your VOM is set to read resistance and not voltage or current. If your multimeter isn't auto-scaling you ought to set it so that it can read resistances like 8 ohms.

What if there was some big capacitor in series with the woofer to limit bandwidth... [Why would anyone do this anyway?]

Can I ask why you are measuring the resistance of your rear speakers, if they are working? What problems are you having?

The 8/4ohms impedance is not measured using a multimeter.

Whats the deal with measuring resistance?

i wanted to find out the ohms because i was looking at getting a new reciever. i'm currently running the sony 935, that is only good for 8 ohms. i was told that because it is 8 ohms only, and my speakers are less, that i could fry my reciever. so i was looking at getting a harman kardon, either the avr325-330 or the dpr 1001. they will do to 4 ohms, or i heard the yamaha will do to 2 ohms.

if a meter is not the right way, then how do you find the ohms, i can't find any info on them?

thx for the feedback

You can measure the resistance of your speakers with a multimeter. You will get the DC resistance of the unit which is typically about 75% of the nominal impedance. Expect to measure about 6 ohms for an "8 ohm" speaker, and about 3 ohms for a "4 ohm" speaker. As suggested above, set the meter for its lowest resistance range and calibrate the meter by making sure it reads zero ohms when the meter leads touch.
