Is not removed in your system or what you have seen until now. Also you have to think in terms of useful band and not infinite band from DC which is not practical and basically useless.
There is no headshell in my system. The cartridge is ONE body with the arm. Look at the picture and you will see there is no headshell, no counterweight, no antiskating, no conventional pieces that just create undesired resonances in the working band!
everything has a resonant frequency 45 .....

As SY explained, it isn't removed from your system either, just shifted outside of the intended usable range.

I think I have being explaining something not known until now....anyway is not just shifting but is also getting rid of mechanical vibrations without affecting the playing and this is what I call highest possible dynamical rigidity in the working band. If you try to do it with a conventional arm-cartridge set-up with no vibration treatment it will not work.....one has to settle around the usual 10 Hz tuning.
The argument was that it is not possible to play the fundamental notes of the organ. Instead it is possible. I have listened organs in all their magnificence all the time.
How is that? The cart has compliance, and whatever it is connected to has an effective mass, no? The cart is coupled to something, it's not hanging in the air.
Any compliance-mass system has a resonance frequency with a Q. So how can it disappear here?

OK, I did. Still I don't understand how you can have a compliance-mass system that has no resonance....?
Can you explain?

As much as I love vinyl I seriously doubt that 8Hz and 16Hz (64' and 32') pipes can be reproduced by vinyl, certainly harmonics of those pipes can be reproduced. I would be surprised if most cutter amps do not have a deliberately limited bandwidth, not to mention the low likely cutter inductance at those frequencies, my understanding is that there is not much below 20Hz other than noise on vinyl. (Groove modulation at those frequencies and amplitudes would excite the cartridge/arm resonance in most instances imho)
Analog master tapes were band limited on the low end by virtue of head response (physics related to head gap length and tape speed) and in fact the problem gets worse at higher tape speeds due to the gap size. (Higher speeds are great for extended high frequency response, but have the reverse effect on the low frequency response, IIRC insufficient gap length at low frequencies for good performance.)

It has no resonance at usual frequency, actually the entire system has no nasty resonances in the entire working band (i.e. audio band + 1 octave below and 1 octave above, at least). That spectrum is clean enough to get more than the full dynamics one can put in a record! I don't think you read carefully.
I would agree, analog and 18hz 😕
I'm running 4, 18 inch woofers for subs ,18 hz is very doable with low excursion and thd, most dont have such capabilities, so whats the big deal,
especially from those running toobs ..

You may have moved the effective resonance, but it's still there, you can measure it ..

Yes, but that i s not eliminating it as you claim. It is just shifting it out of the usable range.
I love how people try to change the laws of physics when it comes to audio. 🙄

More often the limit is set by speakers-room interaction actually! There is a huge masking going on, no matter how a speaker system will measure then one has to put in a room and has to distinguish from real bass in the record and nasty bass that has nothing to do with the original music...but this is another subject.
We are here to talk about this probably because there are very little arguments against the superiority of vinyl?😉

It is not just shifting, you have to dissipate the mechanical energy into something if you don't want it back into your signal. You have to get rid of it otherwise you get troubles....
It's not changing the laws of physics. It's just understanding and using them properly, I am afraid!
Not true, he never changed it , just moved it out of the way ....😛

That's what I said.

Damping and eliminating are not the same thing.

That spectrum is clean enough to get more than the full dynamics one can put in a record! I don't think you read carefully.
So it has a very low freq resonance, like maybe a few Hz or even lower?
BTW you know if two people do not understand each other, it may be due to poor reading or to poor explanation. It's pretty arrogant to assume á priori it's the other guys fault.
Jan

It doesn't matter, you have to focus on the problem (of music reproduction in the best possible way) and solve it. Yes I can measure it and that's why I am so sure! 🙂

Rotomoss (seen his earlier work and I'm a member of audiofaidaite, also recall some articles about him in paper printing)
What the image fails to show is that the entire tonearm is suspended.
(suppose the underwear is hiding other rubber trapezium acts ?)
It is eliminated from the working band! Are you interested in 1Hz reproduction? There is very little damping, actually. Otherwise the transmissibility of the "springs" gets worse (i.e. the slope is slower and that's not good for a really clean bass).Damping and eliminating are not the same thing.

The rotomoss is the minor brother. The arm is very similar. It is wire suspended. The all system is then isolated by means of subsonic suspension.
