If you read and search a bit on this site you'll find we have already venerated the Paragon for its aesthetic, its innovative approach, and it's craftsmanship. Many fall short of loving it for its sound though. As others have said, it would be difficult to believe that such top engineering minds that have worked at JBL in the decades since the introduction of the Paragon were not able to harness modern material, modern calibration techniques, and years of experience to improve on the ability to reproduce sound through transducer improvement. Have you heard the Everest II?
An excellation observation. I might add , Most speakers in the United States designed since 1970 has been built around ever more exotic driver
materials and inexpensive transisters. Thus the emphasis on technology ,
engineering ,technique and change often masquerading as innovation has
rarely bought genuine progress. Speakers today at least to my ears are Hifi-ish and artifical. A result speakers designed earlier in the U.S. , most have emigrated to Japan and Europe. The outstanding speakers of the past has become collectors items. A pair of early Hartsfield can bring over $40,000
