Unfortunately there are far too many poorly designed listening rooms. I have experienced more than my fair share. I have walked out of many listening rooms just shaking my head and wondering how the hell they expect to sell speakers for 4,000 or more in rooms like that. Anyway your 60's are great sounding speakers. What is more important is they sound good in your room. Glad you are happy I'm very happy with both my 60's and 30's. Each are serving their intended purpose very nicely.
