I have thinking about this lately, how much low ,bass output below 120Hz, do typical acoustic programs such jazz horns, strings go? I know that a piano goes down 27Hz, however those notes are rarely used in practice, same with organs. Looking at recordings in my collections, I doubt many classical and jazz programs go much below ~80Hz, It seems recordings with electronic synthesizers generally go much lower than most acoustic recordings,

what's your opinion on the matter?
