Solved! Impedance Difference

Hello. I am kind of new to audio stuff and I'm a but puzzled about a thing. I have a pair of 6 ohm speakers and an amp which says that to work with both speakers at a time, the speakers need to have 8-16 ohms but everything works great with my speakers except the phono, which I assume is from an unrelated issue. What I don't understand is how does everything work even though, the speakers have less impendance then needed.
 
Speaker impedance varies with frequency so you can have a 6 ohm speaker that goes from 4 ohms up and still be rated 6 ohms. Another speaker that goes from 6 ohms up can be rated at 6 ohms but will be easier for the amp to handle.
It's also possible that at higher volumes for longer periods of time the amp may shut down.

Hello.

I have a set of 5.1 ch speaker from SONY HTIB which are rated 2.7 ohm. Now I am planing to use them with 6 - 8ohm rated receiver. I know this combination is not really a good idea. But I still need to manage my budget. So I'd like to know that how critical is it to use this combination and will this make my new AVR damage?

Thanks
 
Using a 2.7 ohm speaker on a 6-8 ohm rated receiver will either blow it up or cause it to go into protection.
Just won't work.
If you have to use them then wire a 4 ohm 10 watt power resistor in series with the plus speaker wire. That will raise the impedance of the speaker to a safe value.
You will also have a problem in that HTS systems rarely have the amp for the subwoofer inside the subwoofer cabinet and AVRs never have sub amps built in.
