For reference, the Holographic Series (@1990) brochure is posted on CSP.
...and in a smaller (but still appropriately large) room, my AR90 with 10" woofers (left) perform just as well as my AR9 with 12" woofers (right). Key innovations of the AR-9 Series (1978-1981) are described in Engineering the AR-9 by Tim Holl posted on CSP, which is an interesting read (Acoustic Research has been among few speaker manufacturers to reveal such detail).the ar-9 would beat 95% of any modern speaker costing less than 5k in a double blind test.
Absolutely! I believe there is broad interest in seeing @amirm test such groundbreaking classics (which remain available and affordable) for comparison with the latest high end models sold decades later. Are they so different? What is the point of diminishing return? Etc.New interesting task for the Klippel.
