SECTIONONE
About Krell
Thank you for your Resolution Series loudspeaker purchase.
This section describes the Krell Legacy, Krell’s innovative loudspeaker design and
technology, and defines key terms used in this reference.
The Krell Legacy
“I design every Krell component to set the standard
for workmanship, style, and performance.”
Dan D’Agostino
High-end audio is a demanding pursuit— an ongoing quest for excellence in
music reproduction that drives equipment manufacturers to strive for the absolute
in design and performance. With a keen understanding of this passionate drive,
Krell Industries, Inc., was founded in 1980.
For more than two decades, Krell has earned a distinguished reputation for engineering innovation and product excellence. The company’s history is replete with
product introductions that have deeply impacted the high-end audio industry. The
most discriminating audiophiles and product reviewers have consistently recognized Krell components for standard-setting performance.
The Lossless Acoustic Transducer (LAT) Series of loudspeakers introduced the next
era at Krell Industries —the era of loudspeaker design and manufacture. The
Resolution Series Loudspeakers apply the same technology and design principles
that are the foundation of the LAT Series. The combination of state-of-the-art
components, extremely efficient, well designed crossover networks, and beautifully crafted cabinets create a unique loudspeaker series, unlike any before.
The Resolution Series Loudspeakers
All Resolution loudspeakers feature heavily braced enclosures with 2" thick baffles
for superior vibration damping. Driver complements are matched to the enclosure
and customized to Krell’s specifications. All crossovers are highly current-capable
and designed by Krell.

The 4-way floor standing Resolution 1 and the 3-way floor standing Resolution 2
loudspeakers are suited for use in 2-channel systems or as the main left and right
loudspeakers in a multi-channel home theater set-up. The 2-way bookshelf
Resolution 3 loudspeakers work well in small two-channel systems or as surround loudspeakers in multi-channel home theaters. The 3-way center channel
Resolution C loudspeaker features nearly the same driver complement as the
Resolution 2, and can be operated full-range.
Unparalleled Sonic Performance
From the first Krell product—the KSA–100 —to the present, Dan D’Agostino has
continually “pushed the envelope” of performance in his search for greater amplifier
power, and now, loudspeaker response. His exploration of technologies, driven by
his never-ending quest to elevate the standard of excellence, has resulted in breakthrough audio designs.
Over the years, the Krell line of power amplifiers, including benchmark products
such as the KRS–100, KRS–200, and the Audio Standard models, has established a legacy of unparalleled sonic performance —the Krell level of performance. The LAT Series, the first loudspeaker series introduced by Krell, brought
the Krell level of performance to loudspeakers worldwide. The Resolution Series of
loudspeakers continues this Krell tradition.
Dan D’Agostino remains committed to the development of new designs and
technologies. And the Krell legacy will continue to evolve with products that deliver
innovative engineering, perfection in build quality, and outstanding audio performance.

Technology
Krell HEAT, or High End Audio Theater, is a design application
incorporated into Krell components to enhance multi-channel
home entertainment systems. A Krell HEAT system is an integrated home theater system consisting of a state-of-the-art
Krell preamp/processor and matching amplifiers and loudspeakers that reproduce two-channel and multi-channel
sources with audiophile sound quality, placing listeners in the
middle of a lifelike environment.
A crossover is used to maximize the efficient delivery of all of
the sound reproduction tasks across the entire audible spectrum. The crossover splits the audible spectrum into separate
frequency bands for the distribution of content to different
drivers in a loudspeaker. A two-way crossover, for instance,
may split the audible spectrum into two frequency bands,
from 20 Hz to 2 kHz and from 2kHz to 20 kHz and above. The
loudspeaker woofer driver reproduces content from 20 Hz to
2 kHz, while the tweeter reproduces content from 2 kHz to
20 kHz and above.

Placement
All loudspeakers interact with the environment in which they are placed. Loudspeaker
performance is influenced by the size, shape, and contents of the listening room as
well as the placement of the loudspeaker within the room.
A Resolution Series loudspeaker is simple to set up and use, and is engineered to
perform well in a wide variety of listening environments. The closer a loudspeaker
is to the rear wall, the more pronounced the bass response. To minimize unwanted
reflected sound and maximize the width and depth of the soundstage, be careful
not to set the loudspeaker too close to the side walls. Krell encourages you to
experiment and find the placement that reflects your personal preference.
When the loudspeaker is in position in the listening area, you are ready to attach
the loudspeaker grille.
Attach the Loudspeaker Grille
Attach the grille to the loudspeaker before you play music. Each Resolution Series
loudspeaker is equipped with a snap-on grille, which consists of grille cord (3)
strung between two metal grille blocks (1). This grille is shipped in the accessory
box marked “grille”.
1. Grasp the grille blocks on each end of the grille and lift the grille out of the grille
box.
On the Resolution 1, 2, and 3 loudspeakers, position the grille block with the
Krell logo (2) on the bottom front of the loudspeaker.
On the Resolution C loudspeaker, place one grille block on the left front of the
loudspeaker.
2. Gently guide the grille locator pins (4) into the two grille holes (14) on the bottom
front of the loudspeaker.
On the Resolution C, guide the grille locator pins into the two grille holes on the
left front of the loudspeaker.

finger of each hand.
4. Pull firmly to stretch the grille cords, until the grille locator pins align with the
two grille holes on the top front of the loudspeaker.
On the Resolution C, stretch the grille cords to the right.
5. Gently guide the pins into the grille holes. You hear a click when the grille is in
place.
Detach the Loudspeaker Grille before You Move the Loudspeaker
1. Grasp the grille block (1) attached to the top front of the loudspeaker.
On the Resolution C, grasp the grille block attached to the right of the loudspeaker.
2. Gently pull the grille block straight out until the grille locator pins slide out of the
grille holes.
3. Remove the grille block with the Krell logo (2) from the bottom front of the loud-
speaker .
On the Resolution C, remove the grille block from the left side of the loud-
speaker.
4. To protect the grille, place it in the grille box until you are ready to reinstall it.

Enclosure
The Resolution Series loudspeaker enclosures feature a Medium Density Fiberboard (MDF) design. Excellent resistance to vibration is achieved using a minimum
1" thickness of MDF. The baffles of all Resolution loudspeakers are 2" thick, which
further damps unwanted resonance. In addition, the liberal use of internal bracing
deadens the enclosures. Ideal operating environments for the midrange and
tweeter drivers are provided by specialized sub-enclosures that isolate these drivers from the resonant effects of the woofer drivers. Large radiuses at the rear corners of the enclosure reduce the effect of internal standing waves, and contribute
to the refined appearance of the loudspeakers.
Crossover Design
Each group of driver units (tweeter, midrange, and woofer) has its own dedicated
crossover circuit board. Each circuit board is made of double-sided fiberglass and
has a number of unique elements. To minimize parasitic inductance and resistance, multiple capacitors are connected in parallel, and air-core inductors are
wound with oversize wire. This design allows each drive unit to handle its portion of
the music signal without strain, maximizes power delivery, and increases signal linearity . High-current polypropylene film capacitors are used liberally in the audio
signal path.
Similarly, the resistors in the crossover networks are connected in parallel to minimize parasitic inductance and maximize current capacity and power dissipation.
Oversized, high-power, wirewound resistors are used exclusively.
All the inductors are air-core types; they do not suffer from any of the nonlinearities
at low signal levels or saturation at high signal levels that iron-core inductors
exhibit. All the inductors are wound with oversize wire, reducing parasitic resistance
to a fraction of an Ohm.
Krell Resolution 1, 2, 3, and C Loudspeakers
continued
Page 18
14
Drivers
All Resolution loudspeakers feature tweeters that have a dual concentric design,
with very well-damped ultrasonic resonance and a response beyond 40 kHz.
The 4-inch midrange driver used in the Resolution C and Resolution 1 features a
1-piece chassis and a 1-piece cone and surround. This type of construction minimizes the resonant properties caused by component part boundaries. The
Resolution 2 uses a 6.5-inch midrange driver that features a wood fiber cone for
wide frequency response and resistance to break up at high playback levels. A
larger motor structure with custom suspension enables long, linear travel for the
cone, contributing this driver’s low distortion.
The Resolution 3 and Resolution 1 employ a unique 8-inch mid-woofer driver.
This driver features an ultra-light magnesium cone for extended midrange frequency response. The 8-inch cone dimension provides better low frequency
projection and impact, and a larger motor extends low frequency response while
lowering distortion. The 10-inch and 8-inch woofers used in the Resolution 1
and 2 feature aluminum cones that are extremely rigid, for a fast response with
enhanced low frequency impact. Here again, a large motor extends low frequency response while lowering distortion.

(SECTION THREE: Anatomy of a Loudspeaker continued)
Page 19
15
Discrete Driver Environment
All drivers in the Resolution Series operate in an ideal environment, which is designed
to preserve clarity and promote an uncolored sonic presentation. To isolate the drivers
from the operating pressures of the main enclosure, the Resolution 1 loudspeaker
employs a sub-enclosure for the midbass driver and the Resolution 2 loudspeaker is
designed with a sub-enclosure for the midrange driver. The midrange driver in the
Resolution 1 and Resolution C loudspeakers and the tweeter in all models have an
integral sealed-chassis design which isolates these drivers from the main enclosure.
Multi-port Design
In the Resolution 1, 2, and 3, the computer-optimized, multi-port design minimizes compression, which can cause loss of sound quality, especially in the
bass range, at higher output levels. This design allows full excursion of drivers
and the resulting depth and range of music reproduction.
Loudspeaker Feet
Chrome plated brass spikes, rubber feet, and locking washers are included with the
Resolution 1 and 2 floor standing loudspeakers. The sharp pointed spikes are ideal
for carpeted floors. The rubber feet protect tile and wood floors.

SECTION FOUR
Connecting a Resolution Series Loudspeaker
to Your System
All Resolution loudspeakers are equipped with two sets of WBT binding posts.
The top set is connected to the midrange and/or tweeter drivers, and the bottom set is connected to the bass drivers. To use banana-type loudspeaker terminations, remove the plastic pins from the center of each loudspeaker connector.
Use a small pair of pliers to grasp the end of each pin and withdraw it from the
connector.
Each Resolution loudspeaker is shipped set up for standard operation, with a
jumper connecting the positive binding posts and a second jumper connecting
the negative binding posts. Follow these steps to connect a Resolution Series
loudspeaker to your system:
1. Make sure that all power sources and components are off before connecting
system components.
2. Locate the loudspeaker binding posts on the loudspeaker back panel.
3. Connect the loudspeaker cable from the positive binding post on the loud-
speaker to a positive channel output on the amplifier.
4. Connect the loudspeaker cable from the negative binding post on the loud-
speaker to a negative channel output on the amplifier.

SECTION FOUR: (Connecting to Your System continued)
Examples follow:
Standard.
For the standard operation of a Resolution loudspeaker, using one
set of speaker cables per channel, leave the jumper connecting the positive
and negative binding posts in place. For each loudspeaker, make the positive
and negative connections to the binding posts, and then connect the cable to
the corresponding terminals on the left and right channels of the amplifier.
Bi-wir
e. To bi-wire a Resolution loudspeaker using two sets of loudspeaker
cable per channel, first remove the jumper connecting the positive and negative
binding posts. For each loudspeaker, first make the positive and negative connections to the top binding post, and then connect the cable to the corresponding terminals on the left and right channels of the amplifier. Next make the
positive and negative connections to the bottom binding post for each loudspeaker, and then connect the cable to the corresponding terminals on the left
and right channels of the amplifier.
Bi-amp.
To bi-amp a Resolution loudspeaker using two sets of speaker cable
and two amplifier channels per loudspeaker, first remove the jumper connecting
the positive and negative binding posts. For each loudspeaker, make the positive and negative connections to the top binding post, and then connect the
cable to the corresponding terminals on the left and right channels of the first
amplifier. Next make the positive and negative connections to the bottom binding post for each loudspeaker, and then connect the cable to the corresponding terminals on the left and right channels of the second amplifier.
IMPORT ANT
Do not disconnect signal cables when the amplifier is on and connected to the
loudspeaker. Doing so will cause a loud pop that may damage your components.
Tighten loudspeaker binding posts by hand only.
Note
When powering up any system, always turn amplifiers on last. When powering
down, always turn amplifiers off first.

SECTION FIVE
Krell HEAT: Home Theater Technology
The Krell Resolution Series loudspeakers are part of a whole family of loudspeakers
newly designed by Krell. The Resolution 2, 3, and C are voiced precisely for use
with the Resolution 1. Together with the Resolution Subwoofer and a select array of
Krell electronics, these components combine to create two Krell High End Audio
Theater (HEAT) loudspeaker systems: The Resolution Theater I System
, and the
Resolution Theater II System
, continuing the Krell tradition of making the best
high-performance audio technology available for home theater.
Today’s home theater soundtracks contain a demanding range of dynamic material,
from the softest music or whispered conversation to the roar of a jet take-off.
The soundtrack plays a key role in the action seen on the screen and its content
is becoming increasingly complex with each theatrical release. Resolution Series
loudspeakers address the demands of these soundtracks in three ways: superior
power handling, ultra-fast response, and high resolution at all levels.
Resolution Series loudspeakers, driven by Krell amplifiers, guarantee that you
will experience the soundtrack of any film, just as the director intended.
