You can scroll down there Facebook page for hours and read and see all the professionals that are using there stands in studio after studio. www.facebook.com/IsoAcoustics/'The IsoAcoustics stand consists of two platforms—one on which the loudspeaker sits and a second which rests on the supporting surface. Each platform has four injection-molded, rubber bushings in each of four corners, which function as isolators (see Photo 1). The two platforms are connected by four aluminum support rods inserted into the bushings. The openings in the bushings are oblong, which “polarizes” them so they enable front-to-back movement of the top, speaker support platform, while minimizing side-to-side movement (see Figure 1). They are also tapered vertically, which enables the support rods to be firmly seated. The system is designed to allow front-to-back movement of the speaker and the top platform, while preventing that motion from being transmitted to the lower platform. If the lower platform remains stationary, the supporting surface is isolated from speaker vibration.'

Speaker enclosure sits on desk, speaker plays sound, enclosure vibrates, desk in turn vibrates..... If you are able to hear the vibrations of the desk, are you able to hear the vibrations of the speaker enclosure as well? How does the law of conservation of energy and mass play into the physics behind either isolating or tethering a speaker to a desk? How does the energy from a woofer cone, that is radiating directly toward a large desk surface, impact that surface? Does an object in the path of an acoustical wave resonate? It has been proven, over and over again, that what we "hear" is more impacted by our imagination, other senses, and presuppositions than what energy is received by our ears and converted into signals. Check out some of the psycho-acoustic research that has been done by Poppy Crum. youtu.be/BYTlN6wjcvQ?t=323

I do not play the snake oil game. I'm old school and have been doing this for 50 years. I will jump on anyone that comes in here with poppy *bleep* and do !

If we're attempting to reduce enclosure resonances, what are some of the tried and true methods for doing this? How might those same methods be applied externally to the enclosure? Enclosure resonances are not what you are trying to reduce with speaker isolation. It is all those nasty's that are transmitted from a speaker. You design the speaker enclosure to be 'inert' best you can like leonski says. Making said already built speaker enclosure inert sitting on your desktop or living room floor while actively producing sound is impossible. The amount of mass required to do that would be more than you can imagine. Exactly, the only way to make said speaker enclosure "inert" is to dampen its vibrations. Isolating from a given surface does not make it inert, it only makes the speaker enclosure inert in reference to said isolated structure. The enclosure itself isn't actually inert, as it is still influencing the air surrounding it. If it is vibrating (resonating) than it is moving. The only way to dampen the speaker enclosure (in the real world, not a theoretical) is to convert kinetic energy into heat. There are a number of materials that do this.

I will jump on anyone that comes in here with poppy *bleep* and do ! Give that YouTube video a watch, you might smile I will say a lot of your questions do not need an answer and I do not watch that stuff anymore. If you need a good speaker stand for a pair of speakers on a desk then the IsoAcoustics stand are very good. I love mine and they improved my sound very much. The first time I saw them I was pretty sure they would work good because I was an aircraft mech for 20 years and when you see a well designed speaker stand like this it makes since. I then did research for a month and read and watched everything I could find on them and I am an expert on finding things out. Up to the point that I heard my speakers sound better because of them I was a skeptic. A good Audio nut is a skeptic. Read Boomzilla threads !

What do you have to lose by giving that video clip 5 minutes of your time? I even provided the URL that takes you directly to the interesting part, which is relevant to this discussion. I love a good debate, I'd hate to see you bow out now.
