Spiders are generally made of cotton,poly-cotton blend, or conex. The Spider is a flexible corrugated woven material that exists just below the cone that helps maintain the linear movement of the voice coil. The basket's rigidity and resistance to resonance help determine the subwoofer sound quality. The Basket is the frame that holds all the components of a subwoofer. Some say foam surrounds are ideal for sound quality and high excursion while rubber surrounds are slightly stiffer, but they last longer. But there is also Urethane, Santoprene, and Butyl that are used. The two main surround types are Treated Foam and Rubber, which enhance the flex and strength properties. The Surround is part of the sub's suspension system, protects the cone, and prevents the cone from being displaced as it flexes out from the basket. Kevlar can preserve its shape under a lot of pressure thus, allowing for better sound displacement. Magnesium is better than aluminum because it is more rigid Kevlar is exceptionally durable, lightweight, and very flexible. It i s the most common material used because of the price and the protection in preventing such things as mold, moisture, and mildew damage Aluminum and Magnesium cause high pitch resonance and lower frequency. A wide variety of materials are used, such as Polypropylene, which is lightweight, more rigid than paper, and has a small influence over sound quality. The Cone, along with the voice coil, is the only moving part. The dust cap is usually made of the same material as the cone. It protects the inner mechanics while contributing to the structural integrity of the voice coil and the cone. The Dust Cap is a curved dome mounted over the central hole of the loudspeaker diaphragm.
