A surround’s quality can have enormous impact on the frequency response of a loudspeaker. By appropriate selection of material and design EP ensures that the cone’s oscillation behavior and the linearity of motion are not endangered. Therefore surrounds with varying thicknesses are produced with extremely high precision. By balancing geometry and material according to the customer’s individual requirements specific damping characteristics of the surround can be realized. EP produces surrounds of rubber in quality classes SBR, NBR, IIR, PNR, PU, FOAM RUBBER and special qualities by vulcanizing. Common shore harnesses are 50, 60 and 75 shore A.
