A 6 ohm speaker effectively IS an 8 ohm speaker. 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.

If its rated 6 ohms then its rated 6 ohms nominal. Its what the manufacturer came up with.
Many speakers are rated at the MINIMUM impedance, not always nominal.
When I make a speaker, the impedance is essentialy the measured DC resistance.
Unless I buy some of those Pioneer 6 ohm drivers, then its impossible for me to go
lower than 8 ohms unless I go down to 4.
