Looking for tonearm inspiration

I'm right here Raul trying to decipher what you just wrote.

Lets see if I get this right. According to you, if a system's (including the room) bass performance is not correct the entire system will sound bad and if a tonearm is not damped bass performance will be poor. So, by extension you are saying that any system that does not have a damping mechanism in it's tonearm is going to have poor overall performance.

The tonearm and cartridge when playing a record are a mass or effective mass sitting on a spring (the cantilever's suspension) which has a specific spring rate (compliance). This mass is going to want to bounce at a certain frequency depending on the size of the mass and the stiffness of the spring. The larger the mass the lower the frequency it will bounce at. The stiffer the spring the higher that frequency will become. This is the resonance frequency. If you adjust the size of the mass and the stiffness of the spring so that the resonance frequency sits in a range were there is no information the tonearm cartridge system will not be excited to vibrate. We know from measurement that there is very little energy between 8 and 12 Hz on a record. Below that you have rumble and warps. Above and you have record noise and then bass. So if you adjust the mass and spring rate so that the system's resonance frequency is between 8 and 12 Hz it will never be excited to vibrate and the resonance will be a non issue. Using damping in this situation will do absolutely nothing as there is nothing to damp. In a situation where the resonance frequency is too high or too low and may get excited damping will raise the Q of the system and limit the number of oscillations the system will make when it gets excited. This is quite useful in very heavy arms particularly tangential trackers with very high horizontal masses. In a properly matched pivoted tonearm set up damping is totally unnecessary and may even be harmful. 

OK Raul, I do not think I can explain it any better than that. If other members find that I am in error please speak up. I you agree please let Raul know because he has a tendency toward disbelief.   
 

@atmasphere  : I not only understand what mijo said in the post I was refer to and before he posted his " black thread " fenomenal discovery for the audio world analog lovers ! ! last post.

My last post is exactly as is or if you like: you need a very well damped tonearm to match a cartridge, not enough to stays in the ideal resonant frequency range. Easy.

R.

Can anybody translate Raul's last post for me? Just the first paragraph.

I got the last paragraph. He is saying even if a tonearm and cartridge are set up correctly you still need a damping device.

OK Raul, Why do you still need a damping device in a tonearm and cartridge that are set up with a resonance frequency of 8 Hz? What exactly are you damping? What does the damping do? 
 

Just the first paragraph.

I got the last paragraph. He is saying even if a tonearm and cartridge are set up correctly you still need a damping device.

Yeah, I couldn’t make it out either. And I can’t sort out if he’s talking about a damping device like a trough or if he means a damped arm tube (another thing altogether) or if he’s talking about the mechanical resonance window.

@rauliruegas , again, use the google translator.


Go to Google,type ’convert Spanish to English’(https://www.google.com/search?source=hp&ei=kOdbX7HwLInbtQbhtpnYBw&q=convert+spanish+to+engli... )
Put your text in Spanish into the box; highlight the English result and paste it here.

When reading a post that you feel you need to respond to, do yourself another favor and drop the post into the Google translator, only this time using ’convert English to Spanish’. Then you can read it correctly.


As another tip, there is something called the ’Dunning Kruger Effect’. This is where a person that knows a little about something tends to think that they are a lot more expert at it than they really are. It tends to cause blind spots in a person’s perception of the world. In this case you might think you are pretty good at English; please use the Google translator.
