Cabinet design
The box design with a narrow baffle -
is not only an
aesthetically neat shape, b t also has some ad
vantages
in terms of aco stics.
The cabinet is made from st rdy
MDF board, which
offers good sonic q alities.
The cabinet is f rther strengthened
with bars,
which in total ens res a very stable constr ction.
Tweeter dri er
We have selected a ribbon tweeter which provides
s perior transient response and a very flat
freq ency response. The ribbon cone is s per light
and only 18 microns thick. It is a sandwich
constr ction made from rosin-al mini m-rosin
that has been hardened at 320 degrees Celsi s.
The magnet system is a 2 row high-efficient
neodymi m magnets in a mo lded chassis of
ceramic carbon steel.
Fishbone shaped contactors in al mini m, res lts
in a low connection resistance and good heat
distrib tion.
The driver has high power d rability and handles
freq encies p to 40000 Hz which makes it DVD-
A dio and SACD-ready.
Woofer/midrange
dri er
After eval ating a large n mber of drivers from
different man fact rers we selected one from Seas,
a company that has a solid rep tation in the area of
high q ality speaker drivers. Yo find Seas drivers
in many well-known High End speakers.
For woofer/midrange we decided on a 6,5"
magnesi m driver from the Seas Excel series that
have extreme performance. We claim that finding a
better 6,5" driver on the market is a very diffic lt
task.
The s rface treated magnesi m cone is extremely
light b t still extremely stiff and effectively red ces
resonances.
The r bber s rro nding makes s re that no edge
resonances are present.
The mo lded metal basket is a
"high flow" type that
is aco stically transparent with high precision as
the basket is shaped exactly d e to the mo lding
process. This makes s re that the basket is very
stable and efficiently red ces resonances. The
basket is absol tely non-magnetic, which
contrib tes to a higher efficiency of the driver.
A strong magnet combined with the light cone
ens res a high efficiency and a good transient
response.
Heavy copper rings mo nted above and below the
T-shaped pole piece red ce non linear- and
mod lation-distortion and increases the overload
margin.
The copper plating of the top and bottom plates

along with a solid copper phase pl g improves the
heat cond ction and th s contrib tes to the high
power d rability.
Gold plated terminals red ce contact resistance
and serves as anti-corrosion.
Large windows in the basket both above and below
the spider red ces so nd reflection, air flow noise
and cavity resonances.
Woofer dri er
Also for the bass register we selected a SEAS driver
of the type coated paper, a very well-tried type with
an nbeatable relation between price/performance.
The coated paper cone is extremely light b t still
extremely stiff and effectively red ces resonances.
The r bber s rro nd makes s re that no edge
resonances are present.

Crosso er /
Binding post
For the midrange and tweeter we have chosen a -12
dB crossover that has a fast transient response and
a minim m of phase shiftings.
For the woofer we have chosen a 24dB crossover.
The connectors are gold-plated and of bi-wiring
type so that yo can connect to the amplifier with
do ble cables (tri-wiring), or connect to two
amplifiers (tri-amping) for f rther improving the
so nd.
The following co pling modes are available:
1. Upper terminal + mid+ lower terminal
(loops present)
Defa lt setting, the lo dspeaker is fed with the
entire freq ency range.
Witho t the loop between pper and lower
terminal:
2. Upper terminal. The signal is only fed to the
tweeter.
3. Mid terminal. The signal is only fed to the
midrange.
4. Lower terminal. Now the signal is fed to the
woofer only.
This gives the possibility of driving the basses with
XTZ S b Amp 1

Practice of sound / Installation and placement tips
This chapter contains common information on
lo dspeaker placement and installation.
This is general r les, so there are exceptions of
some r les
In which room do
you achie e the best
sound?
No matter how good the eq ipment is, in the wrong
listening environment it will inevitably so nd bad.
There are some basic r les concerning a proper
lo dspeaker installation:
Reflections
Carpets, c rtains and soft f rnit re absorb mid
range and high freq ency so nd, and this is
preferable. Big empty area
s, on the contrary,
prod ce hard reflections that may lead to a
bl rry
dialog e. Apart from colo ring the so nd,
the
perspective of the so nd will deteriorate.
Reflections in the room can ro ghly be compar
ed to
the reflections that ca se
ghost pict res on a TV
screen.
Amplification of bass
frequencies
A lo dspeaker tha
t is placed near a wall, ceiling or
floor will amplify lower freq encies in a sometimes
not desirable way (since it may lead t
o an indistinct
so nd reprod ction
). This amplification becomes
even more obvio s if the lo dspeaker is placed near
a corner. Th s
, for a so nd as clear as possible, the
lo dspeaker sho ld be placed at least 30 cm (abo t
12 inch) away from the wall.
Some constr ctions are made to be placed close
to
a wall.
Furniture
Be aware that f rnit
re may vibrate and ca se
noise at high levels.
Room dimension
Q adratic rooms or r
ooms where the length is near
twice as long as the width sho ld be avoided, since
they may create nwanted resonance.
Placement of the
subwoofer
The placement of the s bwoofer in the room
dra
matically affects the overall freq ency response
and so nd level of the system. At low freq encies
the effect of the room is strong. Even a slight
change in the s bwoofer's location can make a
significant difference in the freq ency
balance.
Patience and expe
rimentation is needed to find the
optimal placement. The placement affects the
phase difference between the main lo dspeakers
and the s bwoofer.
One basic r le is to place the s bwoofer together
with or near the front system (especially important
if the front lo dspeaker also covers
bass
freq encies) as this will
minimize the risk of phase
errors in the room.

Page: 8
Cables
Try to keep them as short as possible. By its
electrical parameters, a long cond ctor will have a
bigger infl ence on the so nd than a short one. It
may also work as an antenna and th s
receive
vario s signals that may become a constant noise in
an active s bwoofer.
Make s re that all connections are clean and not
oxidized. All connections sho ld be mechanically
stable, both power, signal and lo dspeaker cables.
Signal cables sho ld be s
eparated from other
cables.
Front speakers
To get the best res lt the front speakers sho ld be
placed symmetrical in front of the listener. The
distance between the front speakers sho ld be
aro nd 80% of the distance to the listener. In other
word
s, the recommended angle between the front
speakers sho ld be 45°.
Why use two
Subwoofer
There are benefits having two
s bwoofers instead
of one.
The maxim m so nd press re level will be higher.
Less dips and standing waves in the room and a
better freq ency response in the room (and i
n
sweet spot).
The power needed will be less
to reach the same
SPL as with one s bwoofer.
Finally
Please remember that good so nd is a matter of
taste, so yo have to experiment to obtain yo r
favo rite one.
We wish yo best of l ck!

Mounting and Connecting tips
Mounting
alternati es
Normally the XTZ 99.36
is placed standing by a
wall. The wall
behind and besides the lo dspeaker
have infl ence both on the
bass level and the bass
characteristics, so please be patient and
try
different distances to the rear and side walls.
Connect using the
correct phase
Always connect sing the correct phase, from the
+-pole on the amplifier to the +-
pole on the
lo dspeaker and corresponding for min s (-).
If yo by accident connect the other way,
there is no risk of damage. However, the
so nd will not be correct, especially in the
lower freq encies.
O erload
At high load d ring extensive time periods, there is
always the risk of overloading the driv
er and
amplifier.
All lo dspeakers have a limited patience
for high power, so be caref l not to play
extremely lo d and not to increase treble
or bass settings to m ch.
By increasing the bass or treble from 0 to
max yo will increase the power by abo t
16 times.
The initial playing
time
It takes abo t 50 to 100 ho r of initial playing time,
for the driver to so nd optimal. D ring this time,
the speaker may be sed normally.

Room Tuning -
Mechanical
adjustment of the
boundary frequency
By sing the s pplied bass pl gs in the bass reflex
gates, yo can alter the lower bo ndary freq ency
on the XTZ 99.36
The level can be adj sted in 6 different levels in the
bass range.
Also the treble level may be adj sted, which allows
yo to perfectly alter the sonic to fit the room,
eq ipment and yo r own taste.
The speaker is parted in two bass reflex chambers,
one for the midrange / woofer driver and one for
the woofer. The ppermost gate is for the
midrange/woofer while the two lowermost gates
are for the woofer.
The fig re below ill strates three basic settings.
Deep bass
With one bass pl gs in lower gates yo have the
deepest possible bass, which may be s itable for
smaller rooms.
This is nder the condition that the bass level is set
at mode 3 (+3dB)
"Quick" bass
Witho t bass reflex pl gs in the gates, yo have a
"q ick" bass which is especially s itable for large
rooms where the lower freq encies often are
amplified by the room.
Neutral bass
With two pl gs in two gates yo have a flat
freq ency response.
This is nder the condition that the bass level is set
at mode 2 (0dB)
This setting also depends on the size and
shape of the room, and also on yo r own
taste, so please has patience when trying
o t yo r prefered setting.
This schematic pict re (which does not shown act al meas red c rves) el cidates the different sonic characteristics of the bass freq encies.

Page: 11
Basic setting for
neutral bass
reproduction
Since the aco stics is determined by a wide range
of external factors there exists no single ne tral
setting that will work properly for all cases.
External factors that have infl ence on the so nd
incl de the room, the placing, o tp t levels etc.
One basic ne tral setting for an average room of
20m
2
is:
Two bass pl gs in two of the two lowermost gates
and one pl g in the gate for midrange.
Treble level set at mode 1 (0dB)
Bass level set at mode 2 (0dB)
Le el adjustment in
the treble range
In the tre
ble range the level is adj stable in fo r
different modes sing the s pplied loop connector.
Level adj stment in the treble range:
Mode 1/ 0dB
In this mode the so nd is ne tral with a
flat freq ency response.
Mode 2/ +3dB
In this mode the treble level is increase by 3dB.
Mode 3/ -2dB
In this mode the treble level is decreased by 2dB.
Mode 4/ -4dB
In this mode the treble level is decreased by 4dB.
In the bass range the level is adj stable in fo r
different modes sing the s pplied loop connector.
Level adj stment in the bass range:
Mode 1/ -3dB
In this mode the treble level is decreased by 3dB.
Mode 2/ 0dB
In this mode the so nd is ne tral with a flat
freq ency response.
Mode 3/ +3dB
In this mode the bass level is increase by 3dB
Mode 4/ +6dB
In this mode the bass level is increase by 6dB

Biwiring
1. Upper terminal + mid+ lower terminal
(loops present)
Defa lt setting, the lo dspeaker is fed with the
entire freq ency range.
Witho t the loop between pper and lower
terminal:
2. Upper terminal. The signal is only fed to the
tweeter.
3. Mid terminal. Now the signal is fed to the
midrange only.
4. Lower terminal. Now the signal is fed to the
woofer only.
Note!
Make s re that all j mpers are connected.
A loose j mper may co rse a short-
circ it
if they jam between the terminals.

"Do-It-Yourself"-
ser ice
We apply "do-it-yo rself" service on all XTZ
prod cts.
If yo by yo rself are able to find o t what part of
the lo dspeaker is defective, yo are f lly allowed
to nmo nt that part (which wo ld normally be a
driver, a filter or the amplifier) and send it back to
s for exchange.
However, if yo are not certain abo t how to do it,
please contact s before taking the lo dspeaker
apart. We can also help yo finding the fa lt.
Yo can of co rse always choo
se to ret rn the
whole lo dspeaker; therefore yo sho ld save the
original package.
To aid service, XTZ prod cts are
constr cted
and prod ced sing common
technology, so that
basically most people
are able to " nscrew" the
lo dspeaker
sing common tools.
If something is
broken
If yo ca se additional defects by yo rself when
nmo nting the defective part, the warranty still
applies if it is obvio s that the part had a
man fact ring defect. In other cases however, the
