Rubber Surrounds

 

A surround’s quality can have enormous impact on the frequency response of a loudspeaker.

By appropriate selection of material and design DKM ensures that the cone’s oscillation

behaviour and the linearity of motion are not endangered.

Therefore surrounds with varying thicknesses

are produced with highest precision.

By particular balancing of geometry

and material according to the customer’s

individual requirements specific damping

characterictics of the surround can be

realized.

DKM produces surrounds of rubber in quality

classes SBR, NBR, IIR, PNR and

Special qualities by vulcanizing. Common shore hardnesses are 50, 60 and 75 shoreA.
