Vibration absorbing damping feet which isolate speakers, amps, turntables and components from vibration and feedback. They prevent speakers from driving the floorboards and enable systems to operate in a vibration free environment isolated from driving shelves or receiving energy from them. Spikes resist the transfer of vibrations, but they still remain in the vibration source, Soundeck damping feet remove the vibrations. They have a stainless steel finish. 73mm dia.
