Un-disseminated research is not evidence. Speculation about the existence of un-disseminated research is even less evidence.Loudspeaker companies most certainly don't publish their research which can impact their competitiveness in the market.
However, there is plenty of published research in psychology and psychoacoustics -- and demonstrations -- which show that sound perception can change in the absence of any change in sound.
