INTRODUCING PROJECT

Our K2 was the creation of a loudspeaker

that would bring the unique JBL Profes-

sional listening experience to the home in

an uncompromising form.

And with the innovative Project K2 S9800,

JBL engineers created a reference loud-

speaker system for the 21st century. Now

the all-new K2 S9800 Special Edition scales

even greater heights. Effortlessly delivering

the full bandwidth and dynamics of even

the most demanding sources – without

suppression at any listening level –

Project K2 loudspeakers offer a sense of

realism and sonic accuracy that will trans-

port you to the concert hall.

It’s every music lover’s dream.

And now it’s come true.

FULL BANDWIDTH AND DYNAMICS,
AND EVERY EMOTION
THE MUSIC POSSESSES

In every field of human endeavor, there

is an ultimate objective – one of such

immense difficulty that many believe it

to be beyond the realm of the possible.

In mountaineering, scaling the Himalayan

peak K2 in the Karakoram of Pakistan is

such an objective. At 8610 meters, it is the

second highest mountain on Earth, and is

generally acknowledged to be the most

difficult and dangerous ascent of all.

Still, many are irresistibly drawn to the

challenge.

After successfully scaling our equivalent of

that formidable mountain, we understand a

little more about the complex matrix of

motivations and emotions that drives the

adventurer.

CUTTING-EDGE

TECHNOLOGIES

Put simply, Project K2 is what happens when

JBL’s expert team of engineers is given

a free hand, no budgetary constraints and

unlimited access to the world’s finest research

and development facilities.

Taking full advantage of proprietary JBL

technologies and six decades of experience in

professional and consumer audio, Project K2

embodies all the pride and passion for

engineering excellence passed down from

JBL’s founder and namesake, James B. Lansing.

The prize-winning K2 loudspeakers draw

heavily on JBL’s unrivalled experience with

high-sensitivity, high-performance horn sys-

tems and professional subwoofer systems.

The result is an engineering tour de force with

state-of-the-art sound.

Employing newly developed, cutting-edge tech-

nologies, including a next-generation Alnico

woofer and a unique dual-compression-driver

Grace and ease

at any listening level

Superbly detailed, outstandingly dynamic

and capable of breathtaking power, the

Project K2 Series will reveal crucial sub-

tleties and emotional elements in your

favorite music that you’ve never experi-

enced before.

And it does so with grace and ease, even at

larger-than-life listening levels.

In celebration of the success of the JBL K2

S9800, we raise the bar even higher with the

K2 S9800 Special Edition by employing key

sonic upgrades (aluminum-metalized

polypropylene film capacitors) and an even

more luxurious finish. The critically acclaimed

K2 S5800 uses the advanced components

and technologies expressly designed for the

K2 Series in the service of your listening

pleasure. And by popular demand, the S4800

brings revolutionary K2 sound and styling to

small- to medium-sized rooms for superlative

fidelity and musical realism.
