Bass- at what frequency does it change from sounding like a string to just a low tone?

At the level of equipment I use, what matters most to me is if I can discern actual notes instead of just low rumbles and thumps. One of my go to sound tracks for bass is One od Emmylou Harris's more obscure albums called "Thirteen". She does her version of Bruce Springsteen's "My Father's House" which has a synthesizer doing a pretty convincing imitation of a pipe organ.

Speaking of thumpers, I'm glad to see that the Hip hop car thumper bass craze has mostly subsided.

jon_5912. This is what KEF seems to be doing. My R3 Metas don't have impressive low frequency specs but they seem to take good advantage of room gain.
