Cabinet design
The cabinet is c nstructed with a narr w baffle -
n t
nly an aesthetically neat shape but als an advantage
in terms f s nics sin
ce y u have a m re stable baffle
which effectively muffles res nances in the cabinet.
The cabinet is made in 25mm MDF b ard, which has
g d s nic qualities.
The cabinet is further strengthened with bars, which
in t tal yields a very stable c nstructi n.
Tweeter dri er
We have ch sen a silk-made s ft
d me tweeter which
pr vides superi r transient resp nse and a very flat
frequency resp nse with ut res nances. The
frequency resp nse r ll ff is s fter n a s ft
d me
c mpared t an aluminum.
Woofer/midrange
dri er
After evaluating a large number f drivers fr m
different manufacturers we selected a driver which is
very c mpetent.
F r w fer/midrange we decided n a 6½" s lid
c ated driver which gives a sm th extended
frequency resp nse with a c ntr lled r ll ff.
The driver is made up f s lid c ated paper which has
g d s und qualities, high strength and l w weight.
The surface treated c ne is extremely light but still
extremely stiff and effectively reduces res nances.
The rubber surr un
d makes sure that n edge
res nances are present.
The m ulded metal basket f "high fl w" type that is
ac ustically transparent and high precisi n since the
basket is shaped exactly due t m ulding. This makes
sure that the basket is very stable and effic
iently
reduces res nances. The basket is abs lutely n n-
magnetically, which c ntributes t a higher efficiency
f the driver.
A str ng magnet c mbined with the light c ne yields a
high efficiency and a g d transient resp nse.

Practice of sound Installing and placing tips
This chapter c ntains c mm n inf rmati n n
l udspeaker placement and installati n.
In which room do
you achie e the best
sound?
N matter h w g d the equipment is, in the wr ng
listening envir nment it will i
nevitably s und bad. There
are s me basic rules c ncerning a pr per l udspeaker
installati n
Reflexions
Carpets, curtains and s ft furniture abs rb
midrange and
high frequency s und, and this is preferable. Big empty
area, n the c ntrary, reflects
it and pr duces a hard
s und that may lead t a blurry dial gue. Apart fr m
c l uring the s und, als the perspective f the s und
will deteri rate. Reflecti ns in the r m can r ughly be
c mpared t the reflecti ns that yield gh st pictures n a
TV screen.

Amplification of bass
frequencies
A l udspeaker that is placed near a wall, ceiling r fl r
will be amplified in the l wer frequencies in a s metimes
n t desirable way (since it may lead t an indistinct
s und recreati n). This amplificati n be
c mes even m re
bvi us if the l udspeaker is placed near a c rner. Thus,
f r a s und as clear as p ssible, the l udspeaker sh uld
be placed ab ut 30 cm (ab ut 12 inches) away fr m the
wall.
H wever, there are excepti ns fr m this rule. F r s me
type f w
alls / r ms it may be advantage us t place the
l udspeaker cl ser t the wall.
Furniture
Be aware that furniture may vibrate and thus create bad
s und at l ud bass.
Room dimensions
Quadratic r ms r r ms where the length is exactly
twic
e as l ng as the width sh uld be av ided, since they
may create unwanted res nance.
Placing the
loudspeakers
H w the l udspeakers are placed t wards the listener is
f great imp rtance.
The front speakers
F r stere listening the l udspeake
rs sh uld be placed
symmetrically in fr nt f the listener. The distance
between the l udspeakers sh uld be ab ut 80% f the
distance between the listener and ne l udspeaker, r put
in an ther way: the angle between the l udspeakers, as
seen fr m the list
ener, sh uld be ab ut 45 degrees. This
means f r example that if the distance between the
l udspeakers is 2 meters, the listener sh uld be placed
2.5 meters fr m the l udspeakers.
Angling?
Either y u can have the l udspeakers angled in t wards
the
listener r y u can have them directed straight ahead.
S me l udspeakers s und better when angled, but this
may als depend n reflecti ns fr m the side walls. By
angling the l udspeakers inwards, y u decrease
unwanted reflecti ns and thus y u get a bette
r stere
perspective.
The correct height
If the l udspeakers are small, they sh uld be placed n
stands r tilted s that they are n the same level as the
ears.
Cables
Try t keep them as sh rt as p ssible. By its electrical
parameters, a
l ng c nduct r will have a bigger influence
n the s und than a sh rt ne.
The subw fer cable sh uld be shielded, t av id n ise.
Make sure that all c nnecti ns are clean and n t
xidised
. All c nnecti ns sh uld be mechanically stable,
b th p wer, signa
l and l udspeaker cables. Signal cables
sh uld be separated fr m ther cables.
Finally
Please remember that g d s und is a matter f taste, s
y u have t experiment t btain it. We wish y u the best
f luck!

Mounting and connecting tips
Mounting
alternati es
N rmally the XTZ 93 WMT Shielded
is placed
standing by a wall. The wall behind and the wall
beside the l udspeaker have influence n b th the
bass level and the bass characteristics, s please be
patient and try different distances t
the rear and
side walls.
Connect using the
correct phase
Always c nnect using the c rrect phase, fr m the
+-p le n the amplifier t the +-
p le n the
l udspeaker and c rresp nding f r minus (-).
If y u by accident c nnect the ther way,
there
is n risk f damage. H wever, the
s und will n t be c rrect, especially in the
l wer frequencies.
O erload
At high l ad during extensive time peri ds, there is
always the risk f verl ading the driver and
amplifier.
All l udspeakers have a limited
patience
f r high p wer, s be careful n t t play
extremely l ud and n t t increase trebble
r bass settings t much.
By increasing the bass r treble fr m 0 t
max y u will increase the p wer by ab ut
16 times.
The initial playing
time
It takes ab
ut 50 t 100 h ur f initial playing time,
f r the driver t s und ptimal. During this time,
the speaker may be used n rmally.

Room Tuning -
Mechanical
adjustment of the
boundary frequency
By using the supplied bass plugs in the bass reflex
gates, y u can alter t
he l wer b undary frequency
n the XTZ 93 WMT shielded.
Als the treble
level may be adjusted, which all ws
y u t perfectly alter the s nic
t fit the r m,
equipment and y ur wn taste.
Closed gate
With the bass plug m unted in the bass reflex gate,
the cabinet is cl sed and the l udspeaker perates
as a cl sed c nstructi n. This yields a m re ”tight”
bass repr ducti n.
Bass reflex
With n plug present in the gate y u have a higher
bass level and the l udspeaker is capable f
handling l wer frequencies.
These settings als depend n the size and
shape f the r m, and als n y ur wn
taste, s please have patience when trying
ut y ur preferred setting.
Le el adjustment -
Treble
The treble range can be adjusted t 2 different
settings.
Le el adjustment in
the treble range
In the treble range the level is adjustable t tw
different m des using the switch n the back f the
speaker.
Mode 1/ - 0dB
In this m de the s und is neutral with a flat
frequency resp nse.
Mode 2/ -3dB
In this m de the treble level is decreased by -3dB.

Service & support
"Do-It-Yourself"-
ser ice
We apply "d -it-
y urself" service n all XTZ
pr ducts.
If y u by y urself are able t find ut what part
f
the l udspeaker is defective, y u are fully all wed
t unm unt that part (which w uld n rmally be a
driver, a filter r the amplifier) and send it back t
us f r exchange.
IMPORTANT!
Always
c ntact y ur dealer r us bef re taking the
l udspeaker apart.
It can als help y u finding the
fault.
Y u can f c urse always ch se t return the
wh le l udspeaker; theref re y u sh uld save the
riginal package.
T aid service, XTZ pr ducts are
c nstructed and pr duced using c mm n
techn l gy, s that basically
m st pe ple
are able t "unscrew" the l udspeaker
using c mm n t ls.
If something is
broken
If y u cause additi nal defects by y urself when
unm unt the defective part, the warranty still
applies if it is bvi us that the part had a
manufacturing d
efect. In ther cases h wever, the
warranty d es n t apply if y u cause ther defects
n the l udspeaker.
