The loudspeaker decoupling prevents unpleasant roar and audibly brings more precision and balance in low, middle and high positions. Acoustic coupling takes place with spikes. They are attached to the underside of the loudspeaker with the tip towards the floor, whereby a support plate is placed between the tip and the floor so that the floor is not damaged. The loudspeaker spikes come in the slim version and are adjustable in height. The cone shape and the small contact carry the vibrations through the housing into the ground. Reverse vibrations that could act on the loudspeaker housing from the ground keep them out because of their shape. Note: Adhesives are not recommended, as this affects the insulating effect of the loudspeaker feet Color: Silver Material: Metal Package Contents: 8 set x loudspeaker Spikes Only the above package content, other products are not included.
