The stands guarantee a flexible and stable positioning of your home theater speakers. They fit perfectly both aesthetically and mechanically with the Cinema M6, M6 Center & S5 and provide you with an easy and stable installation. The stand also hides the speaker cables so there are no loose cables leading to the actual speaker. Included in the package is a stacking bracket to mount two speakers vertically to create a line source. Just as the speakers they are painted in a matte black finish to avoid any reflections. The rubber spikes can be switched to metal spikes. To further add stability and weight the stands can be filled with sand.
