A rigid, but light weight carbon fiber cone along with an edge wound copper voice coil, combine for excellent transient response and an extended and controlled top end roll-off. The frame is heavy duty, aluminum die cast with venting below the flat spider and through the center of the magnet structure to avoid air turbulence and noise. This is a premium, well-crafted speaker designed to bring music to life.
