The W21EX-001 is an 8" cone driver developed for use as a high fidelity Woofer. Choose it when you want piston-like behavior without resonance, smooth extended frequency response, linearized driving force, and low. SPECIAL FEATURES: Natural rubber surround and a specially treated, hard paper cone which is designed to be very stiff without losing the damping capability of paper and requires no additional coating. Perfectly matched moving parts for a smooth, extended frequency response. Large magnet system for improved sensitivity and transient response. Heavy copper rings mounted above and below the T-shaped pole piece, to reduce non linear and modulation distortion and increase overload margin. Copper plating of the top and bottom plates and a solid copper phase plug, which enhance the performance of the copper rings and improve heat conduction away from the pole piece. Gold plated terminals mounted on a stiff bakelite plate to reduce contact resistance and improve reliability. Stiff and stable injection moulded metal basket to keep the critical components in perfect alignment.
