JBL K2 S5800 - Manual (Page 2)

Features
Speaker fitted with a 75mm (3") aluminum-diaphragm compression driver (435AL) and a 25mm (1") titanium-diaphragm
compression driver (045Ti).
Both drivers employ aluminum-ribbon voice coils and neodymium magnets for high output, high sensitivity and
high durability.
The 380mm (15") (1500FE) bass driver is designed for large excursion and power linearity with ferrite magnets and
JBL’s new SFG magnetic circuit.
The 435AL midrange compression driver uses a 75mm (3") voice coil in a compact, neodymium motor assembly that is
encapsulated in a Kapton ® suspension for unmatched durability. The driver is pneumatically formed from an extremely thin
aluminum foil that yields superlative sonic performance. The driver assembly feeds into a rapid-flare horn shape designed to
dramatically reduce second-harmonic distortion.
The K2 S5800 features a 435AL aluminum midrange compression driver and 045Ti ultrahigh-frequency titanium compression
driver, both mated to a specially designed dual-chamber BiRadial ® horn made from SonoGlass ® , a highly dense resin material
that can be precisely molded in an optimum configuration for an accurate, natural midrange and smooth high frequencies,
along with wide dispersion.
The K2 S5800’s 045Ti ultrahigh-frequency compression driver features a neodymium magnet and a ribbon voice coil directly
mounted to a titanium diaphragm to reduce weight and deliver maximum high frequencies. Internally incorporated into the
dual-chamber high-frequency horn, its response extends to beyond 40kHz with a 60° by 30° coverage pattern, providing
exceptionally open and detailed high frequencies, with no harshness or glare, over a wide listening area.
The midrange/high-frequency horn assembly is flanked by dual 1200FE 12-inch Kevlar ® -composite cone woofers treated with
Aquaplas, a mixture of Kevlar fiber and felted paper that combines the rigidity and fast transient response of Kevlar with
the musicality of natural fiber. The Aquaplas treatment provides added rigidity while preserving the sonic neutrality of the
Kevlar/felted-paper cone material, while damping internal resonances, smoothing out the frequency balance and tightening
bass response.
To provide high power-handling capability with minimal distortion, this advanced-technology woofer features a heavy-duty
edge-wound aluminum ribbon voice coil utilizing JBL’s Symmetrical Field Geometry TM (SFG) circuit, a proprietary technology
that lowers woofer distortion by maintaining a symmetrical magnetic field (unlike conventional woofer designs with asym-
metrical magnetic fields) in the voice coil gap. The uniform magnetic field around the voice coil ensures linear cone travel,
and harmonic distortion is dramatically reduced. Performance is further enhanced by the woofer’s die-cast aluminum frame,
vented polepieces for highly efficient cooling and additional refinements.
Complementing these extraordinary drivers, the K2 S5800 is constructed from the highest-grade materials and components,
such as rigidly braced medium density fibreboard (MDF) enclosures, and audiophile-quality crossover components and
internal wiring selected for maximum sonic purity. The loudspeaker employs an innovative crossover network in which a
DC-bias voltage is applied to the capacitors to eliminate the distortion that can occur when the musical waveform crosses
from a positive to a negative value in an audio circuit.
Additional features include a high-frequency trim switch to tailor the treble response to the room and the listener’s
preference, bi-wiring and bi-amping capability, and more.
