That would be rec.audio.tech.

The amp/receiver will power two sets of speakers, and has two buttons on
the front, A and B to enable one or both sets. The rear of the
amp/receiver has terminals for speakers A and B. Under the row of
terminals, there is a warning:

Caution
Speaker A or B: 4 ohms
Speaker A and B: 8 ohms

These are minimum ratings. If you use just one set of speakers, 4 ohm
speakers are fine. If you use both at the same time, you need 8 ohm
or higher.

I have been using a set of 6 ohm speakers and they work on either A or
B, but I'd like to do things right.

That's fine, just don't use two sets of 6 ohm speakers.

Should I get a set of 4 ohm speakers?

Buy speakers that sound good, don't worry about the impedance. Worry about
how they sound.
