2 ohm operation would be a death sentence for many modern receivers' power
transformers, especially those which go to the trouble of spelling out 6 ohm
minimums on the rear panel. Denons especially are notorious for this, but
Pioneers and Yamahas are this way also.

If I was using really low-impedance speakers (such as 2 ohms), I'd put
my hand on top of the receiver and make sure it's not getting too hot
and is well ventilated, especially when the receiver is turned up to
loud volume.

A 6 ohm speaker effectively IS an 8 ohm speaker.
I also wouldn't worry over 6 vs. 8 ohm. Shouldn't be a problem.
(BTW, the loudspeaker specs from manufacturers are often inaccurate,
and impedance will vary with frequencies also.)
They're just trying to be
more accurate in their rating. It just would not be a good idea to runs
two
pairs at once on that receiver.
Agree, unless the receiver manual states otherwise.

First of all, if the receiver can't reliably drive 6 ohms, I'm not
sure
you'd wanna look at it. That's usually an indication of very weak
power
supplies and amplification stages.
Secondly, you're probably pretty safe still, even with 6 ohm speakers.
If
you choose 6 ohm speakers with good efficiency, I doubt you'll have
much
problem even with a receiver that only specifies 8 ohms. I probably
wouldn't risk anything lower than that, though...

Hi,
I found good sales prices for Yamaha and Onkyo speakers, but it
appear
all
to have 6 Ohm impedance and I want to buy an AVR which specifies
8-16
Ohm
impedance. So which speaker fabricants have 8 Ohm speakers...?
Almost all consumer speakers are specified as 8 ohms. See comments
above.
There is
something wrong with 8 Ohms speakers that it looks to be less than 8
Ohm
ones...?
Thanks in advance
