I tried the Ultra 5s with beveled side facing down toward the floor with a screw insert up to the base of my Magico Mini 2 speakers. The reasoning was that the speaker was being isolated from the vibrations in the floor by the pockets of technology in the beveled half and that the screw insert was facing up into the speaker. For a speaker application, that was the intended orientation, that is, until the devices were modified with screw taps on both halves. Now one could experiment to hear which orientation sounded best.
I was ridiculed by advocates on the forum for trying these under my speakers because the vibration was coming from the speaker not the floor and therefor the pockets of technology should be at the bottom of the speaker between it and the stand. That did not work in my application because my speaker is directly coupled to the stand via three massive ball bearing and cup fittings which is an integral part of the design. By contrast, the Ultra 5 seems to decouple the component from what it sits on. The consensus was that they were designed to be placed between speakers and stands and that the vibrations from the floor could be considered secondary to the vibrations in the speaker itself. My speaker ended up not being an appropriate application.
I wonder if these have ever been tried between upper (tweeter and mid) and lower (bass) speaker modules, like the Wilson Watt/Puppy, which are usually coupled to each other with spikes.
With the Ultra 6, it appears that the 5 pockets of technology are designed to be flush against the underside of a component bottom to drain energy from the component. I don't understand how this would work in a speaker application. With the Ultra 5, the device was meant to be slightly separated from the speaker bottom by perhaps a credit card width. With the Ultra 6, if the pockets face up to the speaker bottom - towards the vibration - separating them from the bottom of the speaker by a turn of the thread would render them ineffective. And reversing them so that the 5 pockets of technology face the floor would not work if you add a spike. And the one pocket of technology on the top would not make contact with the speaker bottom either if the device is threaded into the speaker bottom with a screw leaving a gap or space.
So perhaps this design with pockets of technology on top and bottom is most effective under components and not meant for a speaker application if it is also used with spikes or screws.
