Audiolabyrinth, imo the S9800 and S9900 weren't even as good as the previous generation K2's, specifically the M9500. There were some minor issues with the low frequencies but my main issue with them was the lack of tweeter integration. They always stood out when I heard them. The DD67000 is designed and made to be a K2 and for the best since the M9500. I would have them if I didn't own the M9500 and other horns. They're really good!
