Vibratory or Not?


This is a discussion that for me began on the Stereophile forum which went horribly wrong in my opinion. I was wondering though if this same topic could be discussed here as it comes up a lot in one form or another. My background has been about vibratory tuning as far back as the 70's work in the recording industry and continued into home audio and beyond. The audio signal is one that can be easily tuned, I doubt there is much room there for debate, but we will see, it's Audiogon after all. This being the case I have always concluded that the audio signal is vibratory so has anyone I have ever worked with. It's a common and sometimes even daily practice for someone here to make a vibratory adjustment changing the sound which is obvious to all.

On some of these forum threads however you will see posts saying to get rid of the vibration, without any explanation as to how to remove vibration without altering the audio signal. Every vibratory move I have ever seen done changes the performance of the sound. I've also been a part of the variables of the audio signal during play in real time. If the audio signal is not vibratory how does it change?

I invite you to discuss the vibratory structure and nature of the audio signal.

thanks, lets keep trolling to a minimum please

This is a great thread Michael! I was always confuse when companies talked about resonance tuning. For example Shun Mook talks about sympathetic resonance tuning, Marigo simply says it as resonance tuning and Harmonix says it as controlling negative and positive side of the energy. Are they all talking the same thing as you have been for the past 3 decades when you say vibratory tuning ?

 For the past several years after reading your descriptions regarding variable tuning and vibration control I've tried out more and more of your ways and have found that using even a simple wooden chip placed under an equipment or PZCs on walls can seriously affect the sound. This is not something new but it takes my thoughts all the way towards how much can we tune in our preexisting system and how much of an improvement we can make by applying your methods.

And yes this is RoomTune’s 30th Anniversary (can you believe it). I did tuning long before that but 1989 was when RoomTune hit the scene.

Oh wow 30th anniversary thats cool I didn't know that!!. Ever since I have been tuning with your PZC's and using the tunable room that you designed it has brought a new perspective to me towards this hobby and what the variable tuning design can do, it's powerful. Tuning a system base on vibrations or others may say in other ways makes a lot of sense to me.

Am still burning in your Rev 6 Signature speaker hopefully it will be ready for a review soon :).
Oh man I can tottaly relate to that!!  I feel the rev 6 signature has gone into another level of breaking in today. Midrange is sounding so smooth and full. I will let them to settle in more before i post it up :). 
Hope it’s ok for me to share your TuneLand thread.

Hi Michael, no problem at all please do link to my thread. It will be great to have more guys on board.
Say, aren’t you the guy that can’t spell the word totally?


As usual Geoff goes in to his kiddy mode and start sending bad vibes lol!!!
You can't say kill all vibrations when audio is a vibration. Again that's not anyone putting words into Geoff's mouth as he has said this on many occasions on a couple of forums at least.

Exactly that is what im trying to understand from Geoff the man who also promotes using springs under equipments. Which seems to go against his own words. 

It would be nice if one could go along and make this thread more productive by engaging in to a conversation based on thier experiences and learn more from others who have been doing it on a daily basis for years and to Op for decades :). Approaches may differ but learning them is where the fun is.
