4 ohm and 8 ohm

[Bruce53]

With my limted knowledge from reading on this site and Sound & Vision, I get the impression that 4 ohm speakers are the higher quality ones. Is this generally true?
Also, I don't know if the recent failure of my 17 yr old receiver could be due to me upgrading my old 8 ohm center speaker with a 4 ohm newer speaker (didn't realize it was 4 ohm until today). The new speaker works great, but 2 days after I swapped it out for the old 8 ohm speaker, the left and right front channels went completely out. Likely relationship?

No direct relationship particularly. Depends on driver/design choices and the amps they're trying to sell Might try this article https://www.audioholics.com/loudspeaker-design/speaker-impedance

Regarding impedance and quality, the answer is no.

Re that old receiver, impossible to say, and cost prohibitive to find out. Looks like you're going shopping.

A long time ago I asked Dr. Floyd Toole this. He said low impedance is a bad design.

makes sense low impedance puts Stress (heat) on the amp

Mysteriously, my receiver channels all came back on last night when I arrived home from work!?
