When you had them checked out, did you get them measured for frequency response and/or distortion? Or just the good ol' multimeter?

Just with a good ol' meter, and played sound through them. At the time they were available to me, they were just checked to see if they were working. The original owner thought they & tweeters were the problem with his speakers and ordered a new pair of drivers and tweeters. It turned out it was just an internal wiring problem at the HF binding post. He couldn't return the new pair, so he kept them and I acquired them for a project I had in mind that never materialized.
