Can you clarify what you mean by a cello piece that plumbs the depths?Mike, apparently the music that was generally played was soft jazz...but my friend was having none of that. He brought along some pretty good test pieces, along with a Cello piece that plumbs the depths. Apparently the speakers reacted tremendously to all music that he played. So much so, that several members of the audience were in shock at the SQ.
The lowest note on a cello is C2 which if tuned to A440 would give a frequency of 65.4hz
though it is the lowest note on that instrument
