why it took so very long for Dave W to come to the realization that the old tweeter was such a weak part of his design.
LOL, the "realization" came when Focal stop selling OEM drivers to competitors. Many of the older Wilson drivers were made by Focal and were/are superior to the stuff he is using today. The "new" sound may be less offensive. Some may call it "neutral," but it basically just lacking resolution due to the excessive use of paper cones (and a silk dome tweeter). Proac already mastered that particular sound in the late ’80s.
Wilson fans will continue to like them regardless of how they sound.
