TALIS ensures effective elimination of ground vibration. This vibration originate from the speakers and manifests itself in your Hi-Fi system in the form of harmful microphonics.
The additional black Glider at the base of the feet, uses POM* (a material well respected in the HiFi world) which has excellent damping properties. The special shape of the Glider allows for optimal oscillation distribution.  An added benefit is it is now much easier to move the speakers for optimum placement!
* Polyoxymethylene (POM), also known as acetal, polyacetal and polyformaldehyde, is an engineering thermoplastic used in precision parts requiring high stiffness, low friction and excellent dimensional stability       
Spikes "dock" the speaker on the ground. On unstable ground such as laminate or parquet floors, this leads to an audible sound degradation.   
With TALIS, harmful vibrations can be effectively reduced.  If you cannot remove your spikes, use our new b.DISC washers instead.
