SPC 12

The SPC 12 is a powerful subwoofer from Audiocontrol. With a diameter of 12" (30cm), it features a fiber matrix injection-molded diaphragm made of polypropylene, providing optimal thermal efficiency. The weather resistance factor makes it a versatile choice for different environments. Thanks to the included removable subwoofer grille, you get additional protection and flexibility in handling it. A highly durable 3-layer high-temperature voice coil and a rubber gasket complement the robust design. The subwoofer offers strong technical specifications, including an RMS power of 400 watts and an impressive maximum power of 800 watts.
