My Old zenith mc 6190 says to only use 8 ohm speakers but I am testing out one aiwa 6 ohm
Speaker. I used to have a pioneer receiver when I was a teen for 8 ohm speakers but I used 6 ohm 16 inch pioneer speakers. Are most receivers okay handling 6 ohms? Is it mainly 4 ohm speakers that you have to worry about?

It all depends. Too many variables to absolutely generalize.

However, in general the ohms rating for speakers and receivers are not a sharp red line, but a pink fuzzy line. Kinda like a feather boa dropped on the floor.

As much as you try, you cannot break the laws of physics.

the problem is I have quite a few sets of speakers that are 6ohms. i just hope that it doesn't hurt the 8hm only receivers that i have.

Most amps will play well with impedance lower than they are rated for, but you are taking your chances. Most speakers do not have the same impedance over various frequencies anyway. An amp rated for 8ohms should be fine between 4ohms and 8ohms. 2ohms is a lot lower than 4ohms. Going to 2ohms on most amps will put them to bed without their supper.
