PREFACE
Thank you for selecting a Project
K2 S5800 
loudspeaker system. It
represents the sum total of our
research and developmental
efforts in sound reproduction over
the last half century. We have
labored to create a loudspeaker
system with no acoustical or elec-
trical limitations whatsoever. While
the Project K2 S5800 loudspeaker
is itself a new development, the
goal behind it goes right back to
the earliest days of the original
James B. Lansing Sound Company.
But it is your listening pleasure that
ultimately determines how success-
ful we are in this endeavor. It is
solely in the interest of ensuring a
perfect listening experience that
we ask you to faithfully follow the
setup and operation procedures
outlined in this owner’s guide.
This guide exists for several 
purposes. As your owner’s manual,
it contains all necessary back-
ground information and detailed
instructions for setting up your
Project K2 S5800 loudspeaker 
system, including unpacking the
loudspeaker, selecting the correct
location, speaker wire, wiring
scheme and amplification, and
connecting it to its associated
electronics. This information will
be found in Chapters 3 through 7.
In addition, we have included a
detailed description of Project
K2 S5800 
loudspeakers (Chapter 2)
so that you may become thoroughly
acquainted with its unique design
and technological features.
Although physically and materially
imposing, the setup procedure of
the Project K2 S5800 loudspeaker
system is relatively simple. We
strongly urge you to read this 
manual thoroughly before you
begin, and consult it frequently
throughout the process.
Considerations must be made in
placing the speakers; their stature
makes it imperative that you
become familiar with the entire
setup process in advance.
Also, we believe that the historical
and technical information included
will add immeasurably to your total
enjoyment of the loudspeaker 
system. Project K2 S5800 is unpar-
alleled in the field of sound repro-
duction. The story and principles
behind it are an interesting, inform-
ative and fitting precursor to a life-
time of musical enjoyment.

enables us to keep you posted on
our latest advancements, and
helps us to better understand our
customers and build products 
that meet their needs and 
expectations.

CHAPTER 1 – LEGACY: THE HISTORICAL DEVELOPMENT OF
THE JBL PROJECT 
LOUDSPEAKERS
Of those few who seek perfection in
sound reproduction, only a handful
have actually achieved it. The price
is always high. It is a rare occur-
rence indeed when an individual or
group is able to triumph over the
constraints of economic and tech-
nological reality even once.
At JBL, this has happened eight
times. In each case, its engineers
were told to build the speaker sys-
tem they had always wanted to
build. Whatever resources were
required would be made available.
Thus began an ongoing investiga-
tion into new frontiers of sound
reproduction, beginning in 1950, 
and continuing to the present day.
The products that have resulted
from this venture are now known as
the JBL Project loudspeakers. Each
represents the absolute peak of
every technological, material and
engineering innovation available 
at that time, combined into a 
single system. They are Hartsfield, 
Paragon, Everest, K2 S9500/7500 
and
K2 S5500. The newest models are
the K2 S5800 and K2 S9800.
Although differing in performance
details and physical attributes, each
of the Project loudspeakers has
shared a common objective: to ele-
vate sound reproduction to levels
defined only by the limitations of
existing materials and technology.
And despite a spread of nearly 50
years, all Project loudspeakers
have shared many common 
features – testimony to their 
foundation on the technology and
manufacturing techniques upon
which JBL was built.
DEFINING THE PROJECT
CONCEPT
The Hartsfield began a tradition at
JBL that continues today. First, engi-
neer a product as close to perfection
as possible. When it reaches that
level, it is time to make it better.
In 1954, the Hartsfield was signifi-
cant in that it represented not new
technology, but rather a new level
of the all-technical manufacturing
approach pioneered by James B.
Lansing some 20 years before it.
Like its Project series successors, 
it was a high-efficiency system
incorporating compression driver
technology, one combining the
qualities of high output, low distor-
tion, exceptional stereo imaging
and fatigue-free listening. Most
important, it was the first consumer-
available listening system to do so.
In this respect, Project K2 S5800
is at once the most advanced and
sophisticated loudspeaker in the
world today (save for the Project 
K2 S9800
) and a speaker whose
technology is deeply rooted in more
than 50 years of tradition. JBL’s
president in 1954, William Thomas,
described the Hartsfield as “...the
speaker system we have always
wanted to build...the finest compo-
nents ever made available to seri-
ous listeners.”
He went on to describe the process
behind his creation: “Most people
who own and appreciate fine sound
reproduction equipment look for-
ward to the day when they will be
able to assemble a system without
limitation in just exactly the way
they think it should be done. 
“Periodically, a manufacturer gets
this same feeling....The science of
acoustics has provided us with
basic principles – available to all for
achieving precision reproduction. 
It is only a matter of incorporating
these methods into a system design,
and then taking every bit of trouble
necessary to build a system pre-
cisely to the design. It isn't easy, but
that’s the way it is done.”
The Ranger-Paragon, JBL’s second
Project system, was the first seri-
ous attempt at a reflecting speaker
system, and broke new ground in
the concept of stereo imaging.
Essentially two independent full-
range speaker systems installed in
a handsome curved cabinet nearly
9 feet long, the Paragon’s enclosure
was treated as an extension of its
transducers. In essence, the system
had its own “built-in acoustics.” In
many respects the Paragon antici-
pated loudspeaker developments
that would occur years – and even
decades – later.
For nearly 30 years, the Paragon
remained the most acoustically
viable sound system for the home.
Today, along with the Hartsfield
it is still the most sought-after
speaker in the world.
In 1986, JBL introduced a new
Project system that retained the
Paragon’s overall sense of musicality
while upgrading its character by
incorporating three decades’ worth
of continuous development in every
facet of its design. Its name reflected
the pinnacle of achievement it rep-
resented: Project Everest.
For the first time, the rest of the
sound reproduction chain – and not
the loudspeaker or its transducers –
would impose limits on overall sys-
tem performance. Like the Paragon
and Hartsfield, Project Everest
was built around compression 
driver technology and addressed 
a more refined stereo image than
was previously considered 
technically feasible.
