Introduction
hank you for purchasing one
of the Tower series speakers by
Henry Kloss. Both of these
T
Tower series speakers
showcase the lifetime of experience
Henry Kloss brings to speaker
design. Henry Kloss examined all
facets of speaker design to ensure
the highest performance possible in
both of these systems. This includes
cabinet shape and construction,
driver size and materials, and driver
placement. Most importantly, Henry
Kloss has included all the complex
internal circuitry needed to ensure a
seamless dynamic “presence” from
either of these speaker systems.

Overview
Read through this manual before
starting to install your speakers.
Decide where to place the Tower
series speakers in your listening
room. Afterwards, you will prepare
the speaker wires, connect and
listen to the speakers. When you are
satisfied with the sound, you may
conceal the wires.
Unpacking And
Checking For
Shipping Damage
1. We suggest that you keep the
shipping carton and packing
materials. They will be useful in
case you move or ship your
speakers.
2. Upon unpacking your speakers,
examine them carefully for any
signs of shipping damage. If
there is evidence of shipping
damage, do not install or use
the speaker. Contact the retailer
where you purchased them.

Speaker Placement
The Tower series speakers are
magnetically shielded, so they may
be placed next to a TV. Most movie
soundtracks sound best with the
speakers positioned to form a 45
angle (see A, below). If this places
the speakers too close to the TV,
move them further out. Avoid
placing the speakers within 18
inches of room corners (see B,
below). Avoid placing Tower II closer
than 5 inches from a back wall (see
C, below). The bipolar Tower speaker
o
should be placed at least 12 inches
from a back wall. The bipolar design
is discussed on the next page. When
placing the speakers close to a
cabinet or wall unit, position their
front surfaces flush with the front
edge of the cabinetry (see D, below).
Have a clear line-of-sight to the
speakers, so that high frequencies
are not blocked. Do not place
speakers near a turntable. Feedback
could result.

About the bipolar
Tower speaker
The bipolar design of the Tower
provides broad coverage of
sound in large rooms. Symmetric
placement in a room is less critical
than with conventional speakers.
Position the back of each bipolar
Tower speaker 12 or more inches
away from a rear or side wall (see
E, right) for the smoothest sound.
The bipolar dispersion pattern of
the Tower will increase the
apparent depth of the stereo image
for both standing and seated
listeners. The tonal balance of the
Tower will be more consistent than
conventional direct radiator
speakers across a wide range of
listening positions, not just for the
central area between the speakers.
Speaker Hook-Up
NOTE: The Tower series speaker’s
bi-wire connection option (see
page 6) must be connected to one
set of speaker outputs only (either
“SPEAKER A” or “SPEAKER B,”
but not “SPEAKER A” and
“SPEAKER B”).
After you have determined
speaker placement (page 3 - 4),
it’s time to connect them to your
receiver or amplifier. Use at least
16-gauge stranded copper wire for
runs of up to 25 feet, and heavier
gauge for longer runs.

Preparing
Speaker Wires
• Use a wire cutter/stripper to cut
speaker wire into appropriate
lengths.
• Separate the individual leads for
a distance of one inch (see F,
below) at both ends of the wires.
• Strip 1/2 inch of insulation from
each individual lead end at both
ends of the wires. Be careful not
to cut through the wire strands.
• Twist the bare wire strands
tightly together (see G, below). Be
sure that there are no loose
strands (see H, below).

1"
H
G
Making Connections
The two leads of each speaker wire
are differentiated by a ridge or color
stripe down one lead’s insulation,
and/or the use of different color wire
(copper and silver).
• Unscrew two of the speakers’ red
(+) and black (–) connectors to
expose the holes in their threaded
shafts.
• Insert the stripped ends of the
wires through the holes.
• Hand tighten the connectors
clockwise (see I, below). Be sure
no stray strands of wire cross the
connecting terminals of your
speaker, receiver or amplifier.
• Connect both speakers identically
by connecting the red (+) and
black (–) terminals on the speaker
units to their red and black
counterparts on your receiver or
amplifier. Use the marked leads
for interconnecting the red
terminals. Use the unmarked
leads for interconnecting the
black terminals.
• Connecting the speaker components identically assures they
operate “in phase.” “Out of
phase” connections can muddy
the bass or stereo effect, causing
solo sounds to “split” between
the two speakers.
• You could also attach standard
banana plugs to the speaker
wires and plug them into the
ends of the speaker connectors. If
oversized banana plugs are used,
the speakers might not sit flush
on the floor.

Optional Hook-Ups
The Tower and Tower II speakers
have two pairs of input terminals.
These terminals are connected by a
“jumper strap” which may be
removed to allow separate cable
connection to woofer section of the
loudspeaker and the midrange/
tweeter section of the speaker
(see J, below). When removing the
J
“jumper strap,” loosen both sets of
input terminals and slide the
“jumper straps” off. Take care to
save the jumper straps for later use.
Bi-wire connections
Bi-wiring uses an individual twoconductor speaker cable to drive
each separate section of the loudspeaker from a single amplifier
(see K, below).

Bi-amplification
connections
Bi-amplification uses one stereo
amplifier to drive the midrange/
tweeter section of the speaker and a
second stereo amplifier to drive the
woofer section of the speaker.
The following two diagrams show
the proper hook-up techniques.
Use diagram L as your guide if you
have two different stereo amplifiers.

You can also use this connection
technique if your amplifiers
are identical.
If you have two identical stereo
amplifiers, you can also use
diagram M as your guide. This
connection scheme allows placement of each amplifier close to its
corresponding speaker, which in
turn ensures short, low resistance
speaker cable runs.

Optimizing The Sound
Cleaning
Specifications
Of Your System
A small change in speaker
placement can have a large effect on
the sound. Program material varies
greatly, so be sure to listen to a
variety of recordings to prevent
being misled by unusual characteristics of a particular recording.Let
your ears be the guide, and trust
them. When the Tower series
speaker sounds right to you, you’ve
found the best placement.
Amplifier Power
At high volume levels, if the sound
is consistently “grainy” or “gritty,”
or there is noticeable distortion on
deep bass, you may be overdriving
(“clipping”) your amplifier or
receiver. Turn down the volume
control until the symptoms
disappear. If this level is not loud
enough for you, you may need a
more powerful amplifier or receiver.
For Dolby Digital® Systems:
You need to configure the “speaker
size” on most Dolby Digital
receivers. If the Tower or Tower II
speakers are used without a
subwoofer, set the speaker size
option of your receiver to “LARGE”
and the subwoofer option to “OFF.”

The Cabinets
If more than dusting is needed, the
vinyl finish on your Tower II
speakers can be cleaned with a
window or vinyl cleaning product.
Avoid spraying any cleaner directly
onto the speaker grilles to prevent
damage.
The bipolar Tower speaker has a
lacquered walnut or black ash
veneer finish. Use a damp cloth to
wipe off the surfaces.
Dust may be removed from the top
of the grille panels with the brush
attachment of a vacuum cleaner.
If you choose to operate the
speakers with the grille panels
removed, dust may accumulate on
the edges of the woofers, midranges
or tweeters. This will not affect the
performance of the system, and we
advise against trying to clean
the drivers.

Floor Versus Carpets
Each Tower speaker comes with four
rubber feet installed in threaded
sleeves in the pedestal base. These
feet will provide stability on any
flat, uncarpeted floor surface and
many single-layer carpeted surfaces.
* Check that each Tower speaker is
securely positioned at the final
listening position and does not
rock back and forth (see N, below).
Use shims to provide stability if
the surface is not level. The rubber
feet will also help protect smooth,
polished floor surfaces.
Each speaker comes with four carpet
spikes. These spikes can be used to
improve stability on thick carpet. They
will penetrate a carpet and carpet pad
and transfer the weight of the speaker
directly to the actual floor surface.
Important Note: These carpet spikes
will leave four small but distinct
puncture holes in wooden floors and
can damage other surfaces. Do not use
these spikes if you are concerned
about the appearance of the floor
beneath the carpet.
Determine the final listening
position of each speaker before
installing the carpet spikes, since
repositioning a speaker is difficult
once the spikes are installed.
Carpet spike installation consists of
removing the rubber feet and then
adjusting and locking the spikes.
O. Screw one locknut about half-
way down the shank of each
carpet spike.
P. Carefully lay the loudspeaker on
its side.
Q. Pull each rubber foot out of its
threaded fitting. Rotate the foot
counter-clockwise if it resists
slipping out.
R. Screw each carpet spike into a
threaded fitting. Leave a small
gap between the locknut and
the fitting.
S. Place the speaker at its proper
listening position. Adjust each
spike by rotating it until the
speaker is level and stable.
T. Screw each of the locknuts up
against the base to secure the
carpet spike.
