What you heard in the early 90s were the Carver Amazing Ribbon speakers. These new ones under discussion are from his Bob Carver company (the one that makes his tube amps) and were introduced in the last year or two. They are called the Amazing Line Source speakers with a different form factor and topology.
I have not heard them yet, but TAS went ape over them.
