I've owned O3's for several years.
The coloration comments strike me as somewhat curious, as these are quite neutral (especially compared to some other horn designs I've heard) to my ear - until you run the SPLs up. Then they get a noticeably "hard" edge. Many speakers exhibit some form of this behavior, but the O3s get edgy pretty quickly. If you listen loud, I'd approach these with caution.
The other issue is more prosaic, but still bothersome. The foam surrounds disintegrated on both speakers after app. 3 years. A PITA.
