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.
High power-handling capability
results in no limitations on the types
of source material.
Project K2 S5800
has very high input sensitivity; even
a relatively small high-end amplifier
can provide full dynamic range
without compression.
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.
