I dont watch video at work. I am left wondering how thick the strings are and whether anyone can actually push them onto the fret, or even reach the fretboard. Is there a special mechanism for pushing the strings onto the fretboard?

Keys at the top of the body are connected to levers that press the strings against the fretboard. It's necessary not just because of the required force, but because the fretboard is several feet above you while you're playing.

The lowest string is apparently 8mm in diameter, making it about 3x the thickness of your typical E string on an electric bass. As for pushing them onto the fretboard, they'd have to be fairly loose to vibrate at those ridiculous frequencies, so that wouldn't be a problem. The height of the instrument is the problem, hence the robot fingers from the video.

MIDI note number 0 is 8 Hz. You don't even get audible until you're up at around number 16.

OK, so, you could use this for a subaudible, fairly long distance QRSS Morse code audio transmissions.  Neat.  I might have to experiment.

It was produced initially around 1850 by Jean-Baptiste Vuillaume  who was a prolific luthier of the time.

The luthier built forty of these instruments.  That's as many as four tens.  But this time, it's not treble.

I'll see your octobass and raise (lower?) the Rotary Woofer.

Specifications: Amplifier Requirement: 150 watts @ 8 ohms Impedance: 8 ohms 0Hz - 40Hz Frequency Response: 1Hz - 30Hz +/- 4dB Suggested Crossover: 20Hz @ 18dB/octave Sensitivity 94dB 1 watt 1 meter @10Hz Maximum Acoustic Output: >115dB between 1 and 20Hz. Distortion: Typically 3% or less between 1 and 20Hz @90dB

You don't hear below 21-20 Hz because the soundwaves are very, very long. In fact, 20Hz is more than 17 meters long. Top end subs produce sounds lower than this not because much happens acoustically below 40Hz, actually, not much does but the bit that does really does matter. Really expensive subs go down to 17 or even 15 Hz and the effect is very subtle but spectacular.

So is the cost.

I'm no fan of Bach-type organ music but hearing it on a system capable of replicating that steam organ sound is something you should experience once. If you want an example of something to hear, the Telarc recording of Also Sprach Zarathustra's fabric covered hammers on the drums that rumble throughout the piece'll put your heart in your mouth. Such kit is also amazingly good at cleaning up 'underscore'.

shiat, and here I am wondering if I should go with 10" or 12" speakers for my next guitar setup. Maybe time to add a zero to those sizes.

You could also use it to talk to nuclear missile submarines.  I wouldn't recommend that, however.

.270 string to tune about that low on electric bass. There have been a few custom .335 made as well. I have only ever used a .175 for a G# just below low C, on a 35" scale.It was OK to play but over .250 has to feel weird. I barely had the speakers to produce the fundamental, but I always wanted to go down to the C# below it. I would need to add the 21" AccuGroove to my El Whappo Jr. for it though. Most house systems won't play it either. You do hear the harmonic overtones though which can still be pleasant.

Whoops, that factoid is not in this particular article. I read a few before submitting this one. The low string is at C0, which is 16.something Hz. There's another video on YouTube where a MIM curator actually plays the lowest note and explains that you do actually hear sound, but it's from resonant overtones.

You seem to be confusing low frequency audio waves with low frequency radio waves.  Don't do that.

The Mormon Tabernacle organ's lowest note is 16Hz, and the new organ in the new conference center is 13Hz. You can't hear the notes, but you can feel them in your chest during recitals. It's pretty cool.

I've always had a thing for oddball bass instruments.

Check out the subcontrabass flute, the contrabass sax, the contrabassoon, or a duet between an octocontralto and contrabass clarinet.

That. String instruments are more like sawtooth waves than sine waves, so, you end up with all of the even and odd integer harmonics of the fundamental frequency - e.g. 32 Hz, 48 Hz, 64 Hz, 80 Hz, etc.
