Features

Speaker fitted with a 75mm (3") aluminum-diaphragm compression driver (435AL) and a 25mm (1") titanium-diaphragm

compression driver (0 45Ti).

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 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 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 6 0° 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 distor tion, this advanced-technology woofer features a heavy-duty

edge-wound aluminum ribbon voice coil utilizing JBL’s Symmetrical Field Geometr y 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.

suspension for unmatched durabilit y. The driver is pneumatically formed from an extremely thin

horn made from SonoGlass®, a highly dense resin material
