diaphragm did. Both compression drivers utilized newly developed beryllium
diaphragms to provide the lowest distortion and flattest frequency response
possible.
In order to re-create the extremely high dynamic range provided by today’s audio
sources, a brand-new low-frequency transducer was developed from the ground
up, utilizing an alnico magnet, a 4-inch (100mm) edge-wound voice coil, and a
15-inch (380mm) cone. Extensive computer-aided engineering and design effort
were necessary to develop the optimized port tuning used in Project K2 S9800,
and has resulted in a significant advance in the concept of state-of-the-art
acoustic reproduction. As a result of the K2
® efforts, a speaker system with
higher sensitivity and a wider dynamic range became a reality without power
compression or distortion, even at extremely high drive levels.
The K2 S9900 continues the tradition of the K2 S9800 and also incorporates
key design elements from the DD66000. Despite its 21st century power and
sophistication, Project K2 S9900 is a synthesis of tradition and technology.
It reflects the design, material, engineering and manufacturing expertise
developed and refined through nearly six decades of experience that are
the exclusive legacy of one loudspeaker brand – JBL.
