Speakers transmit sound through vibration, and if your speakers are vibrating through their stands or your floor, then you're losing some of the sound quality you paid for. Improper insulation can rob high end audio equipment of much of its sheen and lustre. These speaker spikes raise your cabinets from the floor, allowing more of the sound to reach you. They feature a 6mm thread on top, which screws into an insert requiring a 7mm hole drilled in the base of the speaker. For tiled or laminate floors, support discs are included to prevent damage to their finish.
