The MGT Series uses a combination of magnesium, manganese, iron and aluminum, along with very fine sand, to create a neutral character which constantly remains below the noise floor of your system. The extruded magnesium tubes are alloyed with manganese to make it tougher and stronger. They are covered with ridges to break up standing waves and reflected sound. The tubes are then filled with ultra-fine sand to further dampen vibrations. The top and bottom plates are made with steel, alloyed with aluminum. The final result is a speaker stand that is self-damped, but also with a distributed signature. All solids have a resonance frequency. By blending materials in the MGT Series, Tiglon speaker stands are able to function with no discernible sound of their own to interrupt your musical enjoyment.
