A surround’s quality has enormous impact on the frequency response of a loudspeaker. The shore hardness directly affects the frequency of the speaker. Rubber surrounds also endure a long lifetime, almost 20~30years.

A surround is part of the sub’s suspension system. The surround protects the cone and prevents it from being displaced as it flexes out from the basket. It is usually made of a durable material like treated foam or rubber in order to withstand the strenuous job of producing bass frequencies.

Nitrile -butadiene rubber (also known as NBR rubber) was developed during the 1930s. It is fabricated through the co-polymerization of acrylonitrile (ACN) (polar building block) and 1.3-butadine (nonpolar building block). It is the seal industry’s most widely used and economical elastomer. This is partly because it displays excellent resistance to petroleum-based oils, fuels, water, alcohols, silicone greases and hydraulic fluids. Nitrile has a temperature range of between -54 and +149 degrees Celsius and has a good balance of desirable properties like low compression set, high abrasion resistance and high tensile strength.
