Zeljoh,
To amplify on Mapman's comments, the original Walsh designs used exotic cones that were very expensive to manufacture and were SPL limited. The current drivers are more conventional, cheaper to build and go louder. Some believe that SQ was better with the exotic cones (Dale Harder still makes a speaker using this approach), others feel that the difference isn't really significant
I have minimal experience with the older designs, so I can't comment either way on a comparison. I do like the new Ohms tho.
