manual before using the loudspeaker for the rst me. It may take some
paence in order to make the loudspeaker sound opmal.
If you have no previous experience of these kinds of installaons, or if
you have any quesons, feel free to contact our free of charge support
and we will help you. (See further under the heading of Support on the
last page of this manual).
ABOUT 99.25 LCR
The 99.25 LCR is the third generaon of the 99.25 speaker. It is a 2 way
speaker with a true ribbon tweeter and midrange/woofer driver from
Seas. This new version has several esthecal and funconal improve-
ments and sll delivers the same great sound as 99.25 MKII. New stylish
aluminum feet for increased stability and usability, a new grill with mag-
nec mounng, and easier access to the lter for service.

TECHNICAL PRESENTATION
CABINET DESIGN The box design with a narrow bae - is not only an aesthecally neat
shape, but also oer advantages in terms of acouscs. The cabinet is
made from sturdy MDF board, which oers good sonic qualies.
The cabinet is further strengthened with internal bars, which in total
ensures a very stable construcon.
TWEETER DRIVER We have selected a ribbon tweeter which provides superior transient
response and a very at frequency response. The ribbon cone is super
light and only 18 microns thick. It is a sandwich construcon made from
rosin-aluminum-rosin that has been hardened at 320 degrees Celsius.
The magnet system is a 2 row high-ecient neodymium magnets in a
molded chassis of ceramic carbon steel.
Fish-bone shaped contactors in aluminum, results in a low connecon
resistance and good heat distribuon.
The driver has high power durability and handles frequencies up to
40000 Hz which makes it DVD-Audio and SACD-ready.
WOOFER/MIDRANGE
DRIVER
Aer evaluang a large number of drivers from dierent manufacturers
we selected one from Seas, a company that has a solid reputaon in the
area of high quality speaker drivers. You nd Seas drivers in many well-
known High End speakers.
For woofer/midrange we decided on a 6,5” magnesium driver from the
Seas Excel series that has extremely good performance. We claim that
nding a beer 6,5” driver on the market is a very dicult task.
The surface treated magnesium cone is extremely light but sll
extremely s and eecvely reduces resonances. The rubber surround
makes sure that no edge resonances are present.
The molded metal basket is a “high ow” type that is acouscally
transparent with high precision as the basket is shaped exactly due to
the molding process. This makes sure that the basket is very stable and
eciently reduces resonances. The basket is absolutely non-magnec,
which contributes to a higher eciency of the driver.
A strong magnet combined with the light cone ensures a high eciency
and a good transient response.
Heavy copper rings mounted above and below the T-shaped pole
piece reduce non linear- and modulaon-distoron and increases the
overload margin.
The copper plang of the top and boom plates along with a solid
copper phase plug improves the heat conducon and thus contributes
to the high power durability.
Large windows in the basket both above and below the spider reduces
sound reecon, air ow noise and cavity resonances.

CROSSOVER /
BINDING POST
We have selected a -12/18 dB crossover that has a fast transient
response and a minimum of phase shiing.
The connectors are bi-wiring types so you can connect to the amplier
with double cables (bi-wiring), or connect to two ampliers (bi-amping)
for further improvement of the sound. The following connecng
methods are available:
1. Upper terminal + lower terminal (loops present)
Default seng, the loudspeaker is fed with the enre frequency range.
Without the loop between upper and lower terminal:
2. Upper terminal. The signal is only fed to the tweeter.
3. Lower terminal. Now the signal is fed to the woofer only.
PREPARATIONS
UNPACKING Carefully unpack the speaker, and pay aenon so you don’t break
anything. If possible, save the box for future transportaons. If there
should be damage to the loudspeaker, please contact your retailer.

PRACTICE OF SOUND / INSTALLING AND PLACING TIPS
This chapter contains common informaon on loudspeaker placement
and installaon.
IN WHICH ROOM DO YOU
ACHIEVE THE BEST SOUND?
No maer how good the equipment is, in the wrong listening
environment it will inevitably sound bad. There are some basic rules
concerning a proper loudspeaker installaon.
REFLECTIONS Carpets, curtains and so furniture absorb midrange and high frequency
sound, and this is preferable. A large empty area, on the contrary,
reects it and produces a hard sound that may lead to a blurry dialogue.
Apart from coloring the sound, also the perspecve of the sound will
deteriorate.
AMPLIFICATION OF BASS
FREQUENCIES
A loudspeaker that is placed near a wall, ceiling or oor will be amplied
in the lower frequencies in a somemes not desirable way (since it may
lead to an indisnct sound recreaon). This amplicaon becomes
even more obvious if the loudspeaker is placed near a corner. Thus, for
a sound as clear as possible, the loudspeaker should be placed about
30 cm (about 12 inches) away from the wall.
However, there are excepons from this rule. For some type of walls /
rooms it may be advantageous to place the loudspeaker closer to the
wall.
FURNITURE Be aware that furniture may vibrate and thus create bad low frequency
sound.
ROOM DIMENSIONS Quadrac rooms or rooms where the length is exactly twice as long
as the width should be avoided, since they may create unwanted res-
onance.
PLACING THE
LOUDSPEAKERS
How the loudspeakers are placed towards the listener is of great im-
portance.
THE FRONT SPEAKERS For stereo listening the loudspeakers should be placed symmetrically in
front of the listener. The distance between the loudspeakers should be
about 80% of the distance between the listener and one loudspeaker, or
put in another way: the angle between the loudspeakers, as seen from
the listener, should be about 45 degrees. This means for example that if
the distance between the loudspeakers is 2 meters, the listener should
be placed 2.5 meters from the loudspeakers.
ANGLING? Either you can have the loudspeakers angled in towards the listener or
you can have them directed straight ahead. Some loudspeakers sound
beer when angled, but this may also depend on reecons from the
side walls. By angling the loudspeakers inwards, you decrease unwanted
reecons and thus you get a beer stereo perspecve.
THE CORRECT HEIGHT If the loudspeakers are small, they should be placed on stands or lted
so that they are on the same level as the ears.

8
CABLES Try to keep them as short as possible. By its electrical parameters, a long
conductor will have a larger inuence on the sound than a short one.
The subwoofer cable should be shielded, to avoid noise.
Make sure that all connecons are clean and not oxidized. All connec-
ons should be mechanically stable, both power, signal and loudspeak-
er cables. Signal cables should be separated from other cables.
FINALLY Please remember that good sound is a maer of taste, so you have to
experiment to obtain it.
We wish you the best of luck!
MOUNTING AND CONNECTING TIPS
MOUNTING ALTERNATIVES Normally the 99.36 FLR is placed standing by a wall. The wall behind
and the wall beside the loudspeaker have inuence on both the bass
level and the bass characteriscs, so please be paent and try dierent
distances to the rear and side walls.
CONNECTING USING THE
CORRECT PHASE
Always connect using the correct phase, from the +-pole on the amplier
to the +-pole on the loudspeaker and corresponding for minus (-).
If you by accident connect the
other way, there is no risk of
damage. However, the sound
will not be correct, especially
in the lower frequencies.
OVERLOAD At high load during extensive me periods, there is always the risk of
overloading the driver and amplier.
All loudspeakers have a lim-
ited patience for high power,
so be careful not to play ex-
tremely loud and not to in-
crease treble or bass settings
to much.
By increasing the bass or
treble from 0 to max you will
increase the power by about
16 times.
THE INITIAL PLAYING TIME It takes about 50 to 100 hours of inial playing me, for the driver to
sound opmal. During this me, the speaker may be used normally.

SOUND SETTINGS
ROOM TUNING - MECHANICAL
ADJUSTMENT OF THE
BOUNDARY FREQUENCY
By using the supplied bass plug in the bass reex port, you can alter the
lower boundary frequency on the XTZ 99.25 MKII. Also the treble level
may be adjusted, which allows you to perfectly adjust the parameters to
t the room, equipment and your own taste.
Closed port
With the bass plug mounted in the bass reex port, the cabinet is closed
and the loudspeaker operates as a closed construcon which produces
a more “ght” bass reproducon.
Bass reex
With no plug present in the port you get a higher bass level and the
loudspeaker is capable of handling lower frequencies.
These settings also depend
on the size and shape of the
room, and also on your own
taste, so please have pa-
tience when trying out your
preferred setting.
LEVEL ADJUSTMENT IN
THE TREBLE RANGE
In the treble range the level is adjustable in four dierent steps using
the supplied loop connectors.
Level adjustment in the treble range:
Mode 1/ 0dB
In this mode the sound is neutral with a at frequency response.
Mode 2/ +3dB
In this mode the treble level is increased 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.
BINDING POST/BIWIRING We have selected a -12 dB crossover that has a fast transient response
and a minimum of phase shiing. The connectors are bi-wiring types
so you can connect to the amplier with double cables (bi-wiring), or
connect to two ampliers (bi-amping) for further improvement of the
sound.
The following connecng modes are available:
1. Upper terminal + lower terminal (loops present)
Default seng, the loudspeaker is fed with the enre frequency range.
Without the loop between upper and lower terminal:
2. Upper terminal. The signal is only fed to the tweeter.
3. Lower terminal. Now the signal is fed to the woofer only.
Note!
Make sure that all jumpers
are connected.
A loose jumper may cause
a short-circuit if they jam
between the terminals.

SERVICE & SUPPORT
”DO IT YOURSELF” - SERVICE We apply “do-it-yourself” service on all XTZ products. If you by yourself
are able to nd out what part of the loudspeaker is defecve, you are
fully allowed to unmount that part (which would normally be a driver, a
lter or the amplier) and send it back to us for exchange.
IMPORTANT!
Always contact your dealer or us before taking the loudspeaker apart.
It can also help you nding the fault.
You can of course always choose to return the whole loudspeaker;
therefore you should save the original package.
To aid service, XTZ products
are constructed and pro-
duced using common tech-
nology, so that basically most
people are able to “unscrew”
the loudspeaker using com-
mon tools..
IF SOMETHING IS BROKEN If you cause addional defects by yourself when unmount the defecve
part, the warranty sll applies if it is obvious that the part had a manu-
facturing defect. In other cases however, the warranty does not apply if
you cause other defects on the loudspeaker
WHERE TO SEND THE
PRODUCT FOR A WARRANTY
REPAIR
For service we refer to your retailer.
For quesons regarding service, contact us by email: [email protected]
