The DALI ADJUSTABLE CONES is attached on the bottom of your speakers with the included double sided tape. The use of cones is quite a simple way to reduce loss in sound by isolating your speakers from the surface beneath, and also reduce the amount of bass that can be transmitted to your downstairs neighbour in a apartment complex.
The height of the cones is adjustable with a couple of centimetres, and it is for you to decide whether or not you use the enclosed base plattes to protect the surface of the floor from the cones.
These cones have a diameter of 25mm and a height of 26mm. The base platte has the same diameter as the cones.
