David,
I have a friend who is very familiar with that particular Gofriller. It has very extended and mature response in both directions beyond what most every other cello can reach. My friend and I share experience on the removal of interfering energy within musical instruments ..for cello that is the wolf note. The wolf is caused by a specific polarity of a wave that we can now remove. The same cello absent the interference of that polarity takes less effort to bow (energy is saved) resulting in a net gain of average output of 1.5 db.. The harmonic of the wolf being removed is absent in the spectrum analysis beyond 15 k. There were over 250 octaves of the fundamental of 68 hz. with no interference on any harmonics. Working on the same with audio components as they all accumulate and re generate interfering energy that is returned to the source to be played on and in the music repeatedly. Remove the interference and energy use is reduced. Tom
