JBL Synthesis

JBL Synthesis is a line of speakers and electronics developed through 70 years of scientific research in pro audio originally designed for professionals in music and movie industries desiring a “Studio Grade” experience in their home environment.  Over 80% of Blu-ray soundtracks and many music recordings have their final mastering carried out by a JBL Synthesis sound system.  For 70 years, JBL, Inc., has been the leading manufacturer of professional loudspeakers for recording artists and touring musicians, and in a close collaboration with Lucasfilm® engineers, developed the underlying THX technologies, which set a new standard of realism in movie sound.

With horn-loaded compression drivers (an essential of cinema sound rarely heard in consumer systems), wide-dispersion pure-beryllium tweeters and high-definition crossover networks, Synthesis loudspeakers are among the most powerful and capable instruments ever to be used in home entertainment applications.

JBL Synthesis K2 S9900


Project K2 S9900, one of the most advanced and sophisticated loudspeakers in the world today, is the latest expression in technology that is deeply rooted in more than 60 years of tradition. Like the Paragon and Hartsfield, the K2 S9900 was built around compression driver technology and addressed a more refined stereo image than was previously considered technically feasible.  The K2 S9900 continues the tradition of the K2 S9800 and also incorporates key design elements from the Project Everest. Despite its 21st century power and sophistication, Project K2 S9900 is a synthesis of tradition and technology.
