There are differences, but not earth shaking differences. The slightly larger cabinets, and increased volume of the cabinet help to improve the sound at the lower end and at the low mids. The horn geometry have been redesigned for increased smoothness and reality at the higher end. The mids are better.
The difference is not radical, however. And it is a matter of personal taste. Some long time Klipsch owners like the new line, but others prefer the sound of the older line. Lot of Klipsch owners, for example, will not part with their RF-7, for any speaker in the new line. Others jump at the RF-83 right away.
