INFORMACIJA

The cast frame, High-roll sandwich surround and the heavy magnet are the first things you notice about this subwoofer. When you look closer, you will see other details that help make this driver an excellent performer. The reinforced paper cone with a super strong dust cap is double stitched to the surround. The coil cooling takes place through a large tunnel in the pole piece and with cooling vents in the frame. The coil is 3″ in diameter and wrapped with OFC wire. Push-type terminals hold the cables securely, and the Polycot spider can handle a large X-max.

You cannot see all the things that are important, and the most important of the unseen are Klippel optimizations. Using the Klippel device, all parts of the subwoofer can be monitored during a 10+ hour torture test. During the test, the speaker's power handling capability is truly tested, delivering up to 4 times more than the driver was designed to handle. The purpose of this torture is to identify the weakest points of the prototypes and strengthen them for the final product.
