The steel spikes sing a negative song but are better than no spikes..Not all Thiels accept the same shaft diameter.. The newer Thiels require a threaded shaft the older models are a smooth pressure fit..The Audiopoints will collect and dissipate to ground more cabinet resonance than any other similar device. The ultimate collector and dissipator will be the appropriate Sistrum platform. Please keep in mind the heaviest most dense speaker cabinets often need the most help in releaving their stored resonances. More mass more stored energy, more help required..Tom
