When someone I’m having a discussion with asks me a question I usually give them my answer, and when the same question repeats itself I normally repeat the answer in greater detail in the hope that my answer gets through.
Usually, things are done in the following order if something is in need of being solved:
1. A problem is identified. In this case that would mean that the audio quality of audio production where NS-10’s were used had compromises that could be blamed on the loudspeaker.
2. The easiest solution would be to stop using the loudspeaker for audio productions, or doing something about the problem if that is possible.
The funny thing with this thread is that some people here are trying to solve a problem before they have even identified a problem. If someone could at least give examples of audio productions that undoubtedly were compromised by the use of NS-10’s, then we would have a case to solve. But where are all the faulty mixes made on NS-10s?
I don't see the importance of finding out if another loudspeaker would work as a replacement for the mixing engineer using the NS-10s, they just happened to get the result they wanted and there doesn't seem to be any bad traces in the audio productions that can be lead to the use of this speaker. But somehow there is something that some people here think needs to be solved.
