A complete set of suspension components is included with each speaker. The horizontal dispersion is 360°. They include a 25/70/100 V line transformer with five power outlets, plus the option of low impedance operation (8 ohms). 

The power setting is selected by a rotary switch on the top surface of the cabinet. Each speaker is supplied with a separate top cover that protects the connections and power selector switch from dust and dirt after installation. The bottom of the enclosure is sealed by an aluminum grille.
