Boenicke speakers employ a unique swing base isolation system. They are hung on stainless steel cables at the back and rest on a ceramic ball in cups at the front. They work really well and contribute to the clarity of these speakers.
Speaker vibration isolation
P.S. Audio has a video on YouTube, “RMAF 2018”, on Isoacoustic’s speaker vibration eliminator. The demonstration was impressive. Does anyone have experience with these, specifically the ones that replace the spikes as opposed to the stands? Thank you.
