In order to re-create the extremely high dynamic range provided by today’s audio sources, a new low- frequency transducer was used, incorporating a ferrite magnet, 3- inch edge-wound voice coil, and an Aquaplas™-coated 12-inch cone made of Kevlar® composite, a mixture of Kevlar fiber and pulp material that provides increased rigidity. An EPDM rubber sur- round was chosen for both its flexibility and long life. The Symmetrical Field Geometry™ (SFG) magnetic structure mini- mizes second harmonic distortion by providing a uniform flux field that avoids uneven cone move- ment. The rigid cast-aluminum frame is also designed to mini- mize distortion, as aluminum has no effect on the magnetic field. Extensive computer-aided engi- neering and design effort made to develop the optimized port tuning employed in Project K2 S5800 has resulted in a significant advance in the concept of state-of-the-art bass reproduction. This proprietary align- ment method offers the best damp- ing characteristics and provides extremely fast alignment, eliminat- ing the typical “bass-reflex” sound of a ported system.
All three transducers are built using the most advanced materials and precision manufacturing tech- niques refined from renowned JBL professional sound systems.

Despite its power and sophistica- tion, Project K2 S5800 is a marriage of tradition and technology. It reflects the design, engineering and manufacturing expertise derived and refined through nearly six decades of experience that are the exclusive province of one loudspeaker builder: JBL.
