No slinkys under my speakers, just blue tac as an interface between speaker and stand. Spiked to solid concrete through carpet. Stands filled with atabites. Sounds good to me.
Townshend Springs under Speakers
I was very interested, especially with all the talk. I brought the subject up on the Vandersteen forum site, and Richard Vandersteen himself weighed in. As with everything, nothing is perfect in all circumstances. If the floor is wobbly, springs can work, if the speaker is on solid ground, 3 spikes is preferred.
