This 4" Bass/mid-range is appropriate for a wide range of high-end audio systems, whether 2-way bookshelf speaker, a multi-driver floor standing speaker or a professional line array. 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.
