This version of Spike Fixed Floor Protectors is made for Balance only (shorter spike screw)
Using spike is always necessary as it is well known that it increases the sound quality extensively. However standard floor protectors may scratch the floor if the rack/loudspeaker stand is accidentally moved out of place. The new floor protector has a stainless spike integrated and incapsulated in the aluminum cover in order stay fixed to the floor protector if the rack is moved. Beneath the spike is located a brass spacer that aim to avoid any non-desired resonance or ringing. In the bottom of the floor protector is attached a sheet of cork to damp and protect the floor from the hard metal. The measures are D50xH45mm and the thread is M8 or M6. The foot will build 26-40mm (added height between end of pillar to the floor).
