Professional 8 ohm speaker 8MB500

The 8MB500 mid-bass speaker was developed in response to a specific market need for a 200mm (8 inch) midbass driver that combines excellent linearity with good efficiency and power handling capability. It is primarily intended for use as a midbass driver in compact 2-way SLR speakers with a 1-inch compression driver or tweeter but, thanks to its versatile features, it can also be used in multiway systems. Curved paper cone is formed using a unique wood pulp composition designed to achieve the best possible stiffness and rigidity. This is carried by a polycotton multiroll coating to provide greater excursion when controlling breaking modes. The 50 mm (2 inch) aluminum wire voice coil uses the same ISV (Interleaved Sandwich Voice coil) technology. It is composed of a high strength glass fiber former that carries the windings both on the external and internal surfaces to obtain a mass balanced coil. This results in an extremely linear motor assembly which, in combination with the highly advanced magnetic structure design, provides a high force factor or BL. The voice coil is cooled by incorporating the airway between the back plate of the frame and the magnetic top plate to direct the heated air away from the voice coil and divide and dissipate it. Internal CAD FEA structures were used to optimize flux density and BL factor within the air gap. Due to the increasing use of audio systems at outdoor events, the 8MB500's ability to function in humid environments is a key feature. This was achieved by using a unique cone treatment that makes the cone resistant to moisture.
