will 3 ohm speakers work with 6 ohm receiver

[jmeister]

i have a pioneer vsx 456 receiver 260w, and i was wondering if i could connect a set of sony speakers
ss ts52
ss ts51
ss ct51
ss ws52b
each are 3 ohms, the sub is 1.5 ohms
i was wondering if it would cause any damage if i did this, or if it would be ok.

Be careful, since I tried checking the specs of your AVR but could npt find any suitable on;line resource. You need to research if the impedance range of AVR covers 3 ohms. If not then better to not connect as it may damage both AVR and Speaker. Also on the sub, it seems like a passive sub. Do you have powered sub out from the AVR unit? I havent seen any such AVR with powered sub out.

the avr says "sub pre out" on the back, and it also has a switch that switches between 6 and 8 ohms. i was thinking i could just put it to the 6 ohm setting. i found online that it supports 100w at 8 ohms per channel. I found these sites that have some info on the avr.
this has some info: Pioneer VSX-456 | Owners Manual, Service Manual, Schematics, Free Download | HiFi Engine
this has the manual: https://skydrive.live.com/?cid=81ac819178340d9a&id=81AC819178340D9A!784&sc=documents
I don't know if you can make sense of it, but i don't know much when it comes to audio, so any help would be great.

This question has been answered here previously as well. You could search. Anyway, here it goes again.

(1) Power off the amp.
(2) Hook the speakers up with volume turned all the way down.
(3) Power on the amp.
(4) Play. Turned the volume up very slowly and play at very low volume. Play for sometime and see if the amp is under any stress. If the amp is being stressed it will heat up or cut down or clip. Keep touching the amp to see if it's heating up. If it does, they are not compatible. If not, increase the volume gradually and observe the behavior.
(5) If they sound okay at normal volume levels playing non-stop without the amp misbehaving, forget about the Ohms and enjoy your music.

It has sub pre out hence the support is for powered subs. Unless the sony sub has a seperate power cord apart from the cord that comes from the main sony amp, it is a passive sub that will be incompatible with the pioneer avr.

Also not all older days avr has protection circuits built in to auto shut off if clipping is detected, so experiment carefully

Checkes the spec for Pioneer avr and its been rated 8ohms power supply.And you have 2 Ohms speakers.
Though some say OHMS are nothing to do with speakers or amp,I have a experience of Hooking 4 Ohms SPEAKER to 8 Ohms amp and what i can say is "Nothing wrong to my amp or speakers untill i move beyond the average ,say 2 Oclock angle at volume Nob.But one thing is to say is "2 OHM" speakers cannot deliver the music as like 6 or 8 Ohms. You would miss the quality of Hi range and Vocal a bit.

But try to control the volume as when the speakers OHMS are pretty low compared to receiver, then the receiver will be pushed to accelerate the power with more Current and get heat-up normally,which may affect in long term music listening sound quality.


But in general term the speakers which you OWN are dedicated HT speakers and i feel this should not trouble the AVR much at normal volumes
