Does anyone use wood for vibration control?

If it's not vibrating you would hear nothing at all. I personally have never seen or heard of an isolated audio system. I've only seen HEA marketing using the term isolation as a sales tool.

Repeatedly the simple question is asked, if you kill the vibration than what are you listening to? Audio is vibration and has been described as nothing but vibratory on any scientific level ever taught unless HEA has created it's own science.

Maybe it's time we set up our in-room listening labs and reference this.

Strawman argument alert!

Obviously we’re not talking about the acoustic waves, at least I’m not. I’m talking about the vibrations that interfere or distort the pure signal produced by the speakers. This includes, again obviously, speaker cabinet vibrations, vibrations that interferes with the electrical audio signal running through power cords, fuses, wires, capacitors, speaker crossovers, etc. I’m not sure why some folks are so wrapped up on this false logic. It’s a mystery to me. 

Now, if by the word “tuning” you mean reducing vibration or changing the Fr by applying pressure I’m all for it. But, come on, people! Anyone who hasn’t gotten the memo regarding isolation of speakers yet is living in the proverbial Stone Age, gentle readers. This isn’t rocket science, folks! 🚀

The word isolation strikes fear into the hearts of pro audio enthusiasts. 👻

The only good vibration is a dead vibration. ☠️

Metaphors be with you! 

Ay carumba! Does it really need to be stated that a, say, CD player (or amplifier) does NOT make sound by "vibrating"? Sure, like a turntable, it has a mechanical component (the CD spinner), followed by lots of electronics. If those electronic circuits were to be prevented from vibrating, would you then "hear nothing at all" coming out of the CD player? Who would believe such an obviously preposterous notion?

The fact that my Townshend Rock turntable (and the arm mounted on it) "vibrates" less than most other tables allows me to better hear what is on the LP. (Max Townshend likens the mechanical damping the Rock provides, to the tripod you mount a camera to in order to prevent blurring). If the table "vibrated" more, that vibration would be added to or subtracted from that which the phono cartridge is sensing in the LP groove. You don’t have to be a genius to know that is obviously an anti-high fidelity notion.

The terms I see being used as marketing are the simplistic bumper sticker slogans of "low mass", "new paradigm" (reminds me of Tony Cordesman’s old reviews in TAS and Stereophile. He proclaimed every new amplifier he reviewed---the Adcom 555 comes to mind---to be a complete game changer, upsetting the amplifier world order prior to the introduction of the new paradigm-changing amp), and "HEA" used pejoratively. Hey, if you don’t have any real ideas, you have to come up with some bogus ones, right? Something no one else is offering (for a good reason ;-). Gotta have something to sell. Reminds me of entertainers who can't sing very well, and can't write a song to save their life, so they instead put a lot of dancing into their live show. You don't sell the steak, you sell the sizzle!
