Article from Positive Feedback on misconceptions regarding spikes reinforces using isolation products rather than coupling products (spikes) for improved SQ. The article’s summary and link are below. There are many good speaker isolation products such as Isoacoustics, Symposium, Townsend, etc. I personally use Townsend Seismic Platforms and can attest they perform as advertised making a remarkable improvement in all areas of SQ. Note I copied link but when I preview a graph appears rather than the link. When I click on graph the article opens. If the link does not work contact me and I will type it rather than copy it Sorry.
PF Summary:
- Rigid feet couple vibrations
- Vibration is a two-way street
- Spikes cannot drain energy to a heavier mass
- A small contact point actually amplifies vibrations
- Spikes cannot reduce internally generated cabinet vibrations
- Question one-size-fits-all and no lab report devices
- Isolation means the mechanical path is either broken, or the form of energy is converted to another form
- Properly designed isolation is predictable, repeatable, and neutral in performance
- Isolation will offer clarity that cannot be experienced with coupling, because with coupling comes additional, unwanted vibrations
- Isolation is easy to perceive
- Vibration transmissibility is easily measured
