Dimensions & How to Use - Speaker spikes are 34mm in length not including the thread at the top of the spike. The thread on top of the spike is 6mm in diameter (M6) and if required will fit existing M6 housing inserts. The housing inserts require a 7mm diameter pilot hole drilling into the base of the speaker and they then should be tapped into place. The spikes can then be screwed into the housing easily by hand.

Why Buy - Speakers need to be stable, the more stable they are the better all round performance they will give.  If your speakers are floor standing, spikes should be used to increase their stability.  For laminate, tiled or wooden flooring, support discs are included to prevent the spike damaging the floor.
