Question regarding speakers and receiver - Blu-ray Forum

xlei01 · 02-07-2008, 02:22 PM

Hi guys,

I have a question for all you audio experts out there. I currently have a very good set of speakers and an awesome receiver. The sound produced by these speakers are unbelievable - definitely love them. The only problem is: they're only 4 ohms instead of the 8 that the receiver recommends. So my question is this: what are the consequences of using 4 ohm speakers on that receiver? Meaning will it harm the receiver? Kill it off slowly?

Thanks in advance!

if played at high volume (more current is output), the speakers could cause your receiver to overheat and go into protection mode.

so you can use your speakers, at lower volume and it may be ok...if the receiver shuts itself off, you'll know why.

You may not want to do this, but some of the new recievers are 4 ohm stable. I know the Onkyo 805 is since I have that one. I really shouldn't make too much of a difference though. If you have had them paired up for a while with no problems, then don't worry about it! Besides, if it dies, then you'll just have to get a new one, which is always fun

what crack said... as long as you don't run excessive volume for long periods of time, should be ok.....

Thanks for the advise guys - really appreciate it. Sounds like it's pretty okay to keep this setup. I really want to keep the speakers

The speakers are actually Wharfedales (extremely good sound quality). I got them for an insane price - I guess I never bothered to look at the specs once I saw the price tag on them, given that it says Wharfedale Home Theater speakers.

I did read the manual for my receiver an after a good amount of Blu's played (not back to back), I don't really notice any extreme heat radiating from the receiver - just warm to the touch. I guess that's a really good sign then?

Once again, thanks!

you could also look into a resistor that is made for audio lines. simply put one 4ohm one in line with each speaker and you will have the 8 ohms of res on each speaker.

NOPE !!! tant that easy... we are talking impedance not resistance

if speakers to a reciever are anything like that from a car amp to car speakers then yes a high watt resistor can be used. How do I know this? Simple ohms law and personal car audio experience. I at one time had to use resistors to until i could upgrade to better car speakers.
