The JBL Arena X is the flagship automotive loudspeaker from the Arena Series. It includes a 25mm (1-inch) beryllium tweeter driven by a powerful neodymium motor structure for the ultimate in lightweight performance. The powerful all-new tweeter and 6th-generation ceramic-coated, cast-aluminum Acoustic Lens waveguide seamlessly integrates with the directivity of the companion midrange drivers resulting in greater efficiency, improved dynamic range, reduced distortion, and increased power handling compared to aluminum or titanium tweeters. Beryllium - Element 4 on the Periodic Table - is a rare earth metal that is renowned for the remarkable physical properties that make it the ideal material for a high-frequency transducer. Compared to aluminum and titanium tweeter diaphragms, Beryllium offers 4.5 times the stiffness and three times more damping and does so at only half of the weight. Beryllium tweeters are the centerpiece of the ARENA automotive loudspeaker series.
