Why not the piano as a reference for bass

it is probably the best piano recording i heard but because it is only on youtube i cannot be sure but in fact i think even through youtube i am pretty sure it will be my best piano recording .....

Amazing..

I also use piano as the best instrument to test my system/room not just bass alone but the relation between bass and the other frequencies...

The piano timbre is in a way more complex more multidimensional more hard to get right in recording process as in playback process in a room ...

 I like the music of Seth Kaufman a lot...Not only the sound ...

Thanks....

Among my three favorite pianists only one is well recorded...

( Sofronitsky and Nyiregyházi are badly recorded , they are my two best  only the third  Ivan Moravec is relatively well recorded  but nothing like this recording of Kaufman) 

@mahgister , I particularly like "Repercussion". At one point about halfway through Seth stands up and leans forward and plucks the strings with his fingers.  I didn’t realize that’s what was going on until I saw him perform it live.  It had never occurred to me that plucking the strings of a piano is a thing. 

Aside from that, "Repercussion" gives me chills every time I listen to it.

(In case it’s not obvious, yes I absolutely use solo piano music for evaluating speakers and for showing them off... but I’m showing off "see, that sounds like a real piano" instead of "listen to that amazing bass".)

Thank you, @mahgister!  Very glad to hear Seth Kaufman's music speaks to you too!

Looking at Yamaha's website, it seems at least some Clavinova electronic pianos use actual recordings of single piano notes, played at varying intensities.  The actual recordings are taken from a Bosendorfer and a Yamaha Concert Grand.

During play, the notes are mixed and reverberations from the other strings are calculated, along with reverberations from the soundboard and the body of the piano.  For headphone output, this is done in stereo.

Yamaha has been a leader in digital signal processing with its AV Receivers, and its NS-5000 speaker family has been a classic for decades.  Not to mention motorbikes and jet-skis

I am a professional pianist/ organist, and was an agent for Bosendorfer piano many years ago. I use the 97 key Imperial at my church, and have my favorite Bosendorfer 7 foot, 4 inch model at home. The lowest notes on the Imperial contain so little fundamental frequency energy, that even the most skilled piano technicians are very challenged to tune those pitches properly! The reason for the extra nine notes was for scaling and tone. Strings close to the rim do not resonate as well because the soundboard best resonates in the middle area. This is true of any vibrating membrane on any musical instrument! On the Imperial Grand, now the string of the lowest A on a regular piano crosses almost down the middle of the soundboard, creating its beautiful singing quality with almost organ like sustain! On a Steinway, one can achieve power, but with much quicker attenuation than the Bosendorfer, because the string is much closer to the rim. BUT, there still is no comparison to an organ pipe as a bass reference because of the sheer physics of the pipe itself, creating the true fundamental bass frequency! So yes, the piano is a great instrument for testing speaker accuracy, but for a variety of other reasons, not for bass! And no, I’ve never heard a speaker sound like a live Bosendorfer, but the closer they can get is a great evaluation tool for quality audio reproduction. 

Each piano varies in tonality. But I’d argue that despite piano’s being a so called percussive instrument acoustic piano’s ring with overtones that no bass can match. And no digital piano can match the overtones of an acoustic piano.
