Where does this information come from?

While that is true (they drop below 4 ohms across about four octaves) I never said resistance was not important. What I said was inductance was the more important of the two with speaker wires. I may be hanging out on a limb here, but that is the assertion of both Roger Sanders and our own radio guy, Zapped. rw

As it happens, the speaker cable I recently purchased is considerably lower in resistance and inductance than the cable they replaced. They also sounded better. I leave it to the engineers to determine any causal relationship but I'll bet you can guess which attribute I found more compelling!
