Hi all,
I'm aware that using low impedance speakers places a higher load on the amp which can overheat it. My question is if i'm using within spec speakers for the fronts and sub, can I get away with using lower than spec impedance speakers for the rears only?
This is for a budget system in the basement. I have an old Onkyo receiver (s3400 I think), rated for 6-8ohm speakers at 100W. But I only have the front speakers and sub that came with it, that are 6ohms. I have some spare old speakers from an ancient Sony DAV-c990 system, that are rated 3ohms. If i use these speakers for rears only, and don't try and blast the roof off with volume, what're the chances of wrecking the amp?
Obviously what I should do is buy some in-spec rear speakers (or a whole new system), but cash is tight right now. The system sounds much better as 5.1 even with these old sony speakers, than it does as 3.1 if I don't use them.
The surround speakers are restricted range, with a 180Hz crossover set on the amp, so they are not trying to put out loads of bass (they only have 2 inch cones on them), and it seems bass signals through low impedance speakers are the most demanding, not midrange/treble.
What say you all?
Thanks!
Jon
