Well...

"Digital Compatible" - lots of companies producing audio equipment were putting that or similar labeling on their gear after CDs first came out.
"Magnetic Field Compensated" - don't know how they could do that, unless they put a big Faraday cage inside the cabinet. Which I highly doubt.
The frequency response pattern - Probably accurate. If it weren't, I would think they would have run afoul of the FTC or some other alphabet soup gubmint agency.

When Avery Fisher owned Fisher Radio, it was a respected outfit that produced quality equipment.

After Avery sold out to Emerson, the quality started going downhill. Emerson retained Fisher's team of German engineers to design the receivers, but I am sure they also had their bean counters breathing down the necks of those engineers.

After Emerson sold the Fisher brand to Sanyo, the brand really went downhill from there. They finally faded into the history books.

By the time your speakers were built, Sanyo had owned Fisher for several years. I'm not saying your speakers are no good. Let's just say Fisher was, ah, past their prime by then.
