Subwoofer-Speaker Cones define the mechanical and acoustic behavior of a loudspeaker. Cone geometry, stiffness, and moving mass control efficiency, frequency response, and distortion. We stock cones in paper, polypropylene, carbon fiber, and Kevlar®, each with unique traits. Paper provides excellent damping and a smooth tonal balance. Polypropylene resists moisture and keeps compliance stable in harsh or outdoor conditions. Carbon fiber offers the highest stiffness-to-weight ratio, reducing breakup modes and distortion at high excursion. Kevlar® combines strength and low mass, giving a rigid yet responsive cone for powerful, accurate sound.

Each cone is precision sized to match specific frame diameters, surround interfaces, and voice coil IDs. This ensures proper alignment and maximum mechanical stability. Material stiffness and geometry maintain piston-like motion and minimize cone flex under load. Use our cones to restore OEM drivers, upgrade for higher output, or build custom designs. They deliver the structural integrity and acoustic control needed for accurate, durable, and powerful subwoofers.
