Break-through Technology in Resonance Control
Marigo VTS (Vibrational Tension System) dots work on the mechanical resonant frequency of your components. Using constrained layer damping, VTS dots dissipate mechanical vibrational energy that adversely affects your audio components. They are available in a variety of sizes for a wide range of applications.
"...Marigo's VTS Tuning Dots have been one of the most effective and dramatic steps I have taken to improve my system's performance. The improvements were not sublte. They brought great transparency without losing musicality. Clarity, dynamics, inner detail, midrange bloom, bass slam and articulation have such an improved sense of openness that they represent a major paradigm shift in resonance control.
Using the Dots on my speakers wrought a greater improvement than any cable or component swap I've made in recent years. I was hearing a fantastic transformation.
Application of the VTS Tuning Dots to the window behind the listening seat. This is a large window measuring four feet by eight feet. Improvements in soundstage dimensionality and image clarity were readily apparent, as well as the removal of harmonic smearing..."

I recommend starting with woofer cones (where the dots removed a slight upper bass chestiness from my Aerials)

Applications
For Loudspeakers, the 3mm White Dots are made specifically for loudspeaker domes like tweeters and midranges. They are NOT for cone midranges or woofers. Use up to 3 dots per dome driver.

For Electronics, the 3mm White Dots can be used on the following:
• ALL solid state devices: integrated circuits, voltage regulators, digital chips, 1 dot per device
• Output transistors: 1 tuning dot (please degrease transistor first)
• Medium size octal base vacuum tubes –- tip of key pin: 1 tuning dot per tube
• 9 pin miniature vacuum tubes –- centered on bottom: 1 tuning dot per tube
