If we were to judge the 901 in terms of the best sound available, then, we would say that it produces a more realistic semblance of natural ambience than any other speaker system, but we would characterize it as unexceptional in all other respects. It is ideal for rock enthusiasts to whom sheer sonic impact is of paramount importance, and for classical listeners who want the next best thing to ambient stereo without the cost and the bother of rear-channel add-ons. However, we doubt that the 901 will appeal to perfectionists who have developed a taste for subtleties of detail and timbre.
...in their day they were a part of the evolution of audio. Just because it is IN to be a Bose basher....at least know what you are talking about. The 901's were not the best, but far from the worst...... in their day they were a unique sounding system.....that provided many hours of fine listening, when set up properly with the right equipment....and for partying , only to be toped by the Voice of the Theatre speakers......the good old days....long gone but not forgotten.
My friends system at the time was a Thorens TT with a Mac tube amp and the original 901's.....and They sounded Sweet playing that ole Rock and Roll.
