What's the worst that could happen? Onkyo 805 question - Blu-ray Forum

TigredelaJungla · 10-21-2008, 08:25 PM

Guys,
I need your advice, I just ordered an Onkyo 805 refurbished, very good deal at $400 w/1 year warranty, I could not let it go even though I'm not ready yet to set up a nice home theatre due to actually living at an apartment but moving pretty soon to a medium size house.
What I have right now is a Sony Dream Theatre DVD/receiver combination with HDMI output only, nice little set up for an apartment but the speakers I just found out are only 3 ohms. I will need to test my receiver to make sure is working right but I'm afraid if I hook up those 3 ohms speakers it will either blow away the speakers or overheat the receiver, somewhere I read that this receiver can manage 4 ohm speakers but 3 ohms, I don't know. Please help this audio ignorant.

You can always just let the audio pass through to the TV. I am pretty sure that this will blow out the speakers you have even at 4 ohm.

Don't worry about the receiver. Worry about your speakers.

DONT USE THOSE SPEAKERS!!!

They will not generate enough resistance for the amp, it will cause it to get very hot. My guess is that the Onkyo would damage the speakers before it would damage itself, but I would not risk it. If you mess up the amp, you've got a $400 paper weight.

I'm not even touching this one.

You could always test the receiver by using the headphone jack (with an adapter of course).

As McDaddy mentioned, I won't risk it. I'll test it at my brother's house, he does not have top of the line speakers but they are at least 8 ohm and I'll let it control the volume knob, just in case. Thank you all for your advice.
