Getting back to the design principles of something like the Mye stands and to the point of them making any audible or measurable differences (and please note this is not for the benefit of our resident "Scientist" or his colleagues who seem more than content to sit in their ivory towers exclaiming "myth" or "woo" when it comes to time tested loudspeaker design principles they simply do not understand, but to those that are still contemplating the question)... doppler distortion, phase modulation distortion, and modal baffle vibrations are real world considerations in speaker design. They have been measured and documented by the likes of Paul Klipsch, Siegfried Linkwitz, John Kreskovsky, Rod Elliot, and many others for years if not decades. In fact, a main reason for the invention of the multi-way loudspeaker system was to isolate the relative excursion in drivers to particular frequency ranges to minimize the modulation effects on the shorter, more affected wavelengths from the larger excursions needed to reproduce lower frequencies.
Moreover, the Magneplanar's two dimensional design, along with its rather large dimensions, offers very little in the way of structure to control the energy generated by the moving mass of the low frequency driver. So what happens to this energy? It is transmitted quite efficiently to the panel (baffle) itself, resulting in movement. This is a fact... and you can measure it yourself with less than twenty bucks worth of office supplies. You'll need some good adhesive tape (I used gaffer's tape), a laser pointer, a pencil, and some graph paper.
You'll need to firmly attach the laser pointer to the top of the speaker, pointing its spot on the wall behind the listening position. Tape the graph paper to the wall underneath the laser's dot, and now crank up the tunes. You'll see substantial deflection of the dot. And if you're willing to pull the ribbon connection covers from the speaker, you will also see that the vibration introduced into the panel itself is also affecting the movement of the aluminum ribbon. Now disconnect the bass output from the external crossover and notice the change in the movement of the ribbon.
So there are two issues here. Intermodulation of the ribbon induced by panel resonance/vibration, and a non-linear back and forth motion of the entire panel (non-linear as the deflection is more severe at the top of the speaker than at the bottom).
At this point, for those of you that do not believe that the intermodulation and phase modulation components introduced by the movement you have observed will not be measurable, you may as well stop reading now and retire to your own ivory tower. They are measurable and, in fact, have been measured in single drivers let alone when a HF driver is so affected by the rather significant baffle movement caused by the LF driver in this case. For those of you entrenched in vinyl playback, it is not unlike a poorly mismatched cartridge and tonearm where the compliance of the stylus/motor assembly and the mass of the tonearm result in a resonance in the audible range, or one so low that you end up with a warbling effect. Clearly vibration introduced by the stylus movement itself, and reintroduced to the cantilever by the movement of the supporting structure, can severely impact the sound.
The point being that IF the Mye stands offer a noticeable reduction in the deflection previously observed, and/or serve to better control the panel's vibrations, their effect WILL be measurable. I won't go into whether or not "you" will hear a difference as that depends on many things, but I wanted to point out that the design concept of better "locking down your maggies" is not snake oil, but based on valid, time tested loudspeaker engineering concepts that will in fact offer measurable improvements.
Note that I don't own Mye stands, nor am I affiliated in any way with the product. I have simply done my own mods to address the above issues and have been impressed with the results... and, to be honest, get a little annoyed at some folks with their preconceived notions that claim to have made "tests" to arrive at their conclusions when in fact none were actually done.
Ok... I know this horse is probably long done, but I couldn't resist another lash or two.
For those considering bringing more detail to their 3 series maggies, I still think this a viable and non-invasive mod, and worth considering. If you have doubts, try the measurement and observe your ribbons at the louder end of the spectrum you listen.
