You will have more apparent bass when a very low velocity material is added to the equation. Slower than lead like all the rubber and spongy materials. Like placing your hand over your mouth and speaking. No highs no breath of sound mosly lows. The Shear velocity of the material chosen, geometric shape of the device..shape and speed of the material above and below are also of great importance. Your audio room will sound best with no right angles and corners as will every other area of your component high fi. Only a small portion of what takes place between 2 or more materials and their shapes. Tom
Shocked removed spikes, used blue tack, what other non spike footer
My floor standing speakers, monitor stands always came with spikes so I used them always, it's the way they were designed at least I thought. I know everyone can't do this because of there floor type, mine is hardwood over concrete slab. Bass, more natural tone( I'm a tone junkie) gives the music a nice rhythm, may just be flavor of month but I'm really enjoying it. Highs maybe little rolled off, I just did it yesterday, maybe not as hifi, but no lose of information. Have other people experienced this.Can someone with my floor type suggest a nice reasonable priced non spiked footer, these are floorstander filled with shot so pretty heavy,maybe 70- 80 lb. thanks

I find it some what ironic that the Acoustic Coupling Disc for which I was granted a design patent in 2012 and updated again in 2018 is now being used in conjuction with a so called isolation device so it can become more effective and efficient when terminated to the higher mass of ground. So what is it.. an isolator or a grounding scheme..or just a??? Tom |
There has been a peer review of the LIGO results. Was there a mis reading of the collected data.. was it gravity waves or still just noise? Tom https://www-newscientist-com.cdn.ampproject.org/v/s/www.newscientist.com/article/mg24032022-600-excl... |
Geoff, I told you 3 years ago we have a seismologist on staff...you are older now than you were back then. You cannot isolate a seismic wave. Without shear motion or a shear wave there cannot be a compressive wave. A voice coil's initial motion is a polarity of shear the other polarity travels on and thru the material. The air that travels that material in motion is what you hear. The shear velocity and motion of that material is what causes the air to vibrate. There is first shear motion only and then the molecular motion of the air that follows. Super hard materials sound just like that. A little goes a long way. The materials we prefer the sound of, have a shear velocity closer to the speed of sound in air. Ceramic not being of sound mind or sound ear. Lot more for you to find out. The LIGO is mechanically grounded to Earth. Tom |
Nonoise, What was compared were factory supplied parts costing less than a buck compared to a hundred dollar part. Like comparing a cast resistor to a Mundorf resistor..not supposed to matter but easily heard..go further and our design would be like a Vishay Z foil resistor compared to a Mundorf. Remember who grounded their isolation device with a coupling device that looks similar to my Acoustic Coupling Disc. Why such a choice? Tom |
The LIGO foundation must have been poured Jello your most favorite flavor Moby Grape. Debbie is available anytime for consultation with sight and sound as she travels in search of minerals, oil and gases..She uses both shear and compressive waves as part of the discovery process and microphones whose shape is designed to reject surface reflections that re enter the signal path..that generate more Interfering Energy..geometry is like our Audio Points so it maintains one polarity of shear and rejects the other. Keep Looking. Tom |
