Cabinet design
The box design with a na ow baffle and cu ved side
-
is not only an aesthetically neat shape, but
also has
some advantages in te ms of acoustics, since
nonpa allel
walls muffles inte nal esonances of the
cabinet.
The cabinet is made in stu dy
MDF boa d, which has
good sonic qualities.
The cabinet is fu the st engthened with ba s, which
in total yields a ve y stable const uction.
Tweeter dri er
We have chosen a ibbon tweete which p ovides
supe io t ansient esponse and a ve y flat f equency
esponse The ibbon cone is supe light and only 18
mic ons thin. It is a sandwich const uction of osin-
aluminium- osin that has been ha dened at 320
deg ees Celsius.
The magnet system is a 2 ow high-efficient
neodymium magnets in a moulded chassis of ce amic
ca bon steel.
Fishbone shaped contacto s in aluminium, yields a
low connection esistance and good heat de ivation.
The d ive has high powe du ability and handles
f equencies up to 40000 Hz which makes it DVD-
Audio and SACD- eady.
Woofer/midrange
dri er
Afte evaluating a la ge numbe of d ive s f om
diffe ent manufactu e s we selected one f om Seas,
a company that has a solid eputation in the a ea of
high quality speake d ive s. You find Seas d ive s
in many well-known High End speake s.
Fo woofe /mid ange we decided on a 6,5"
magnesium d ive f om the Seas Excel se ies that
have ext eme pe fo mance. We claim that finding a
bette 6,5" d ive on the ma ket is a ve y difficult
task.
The su face t eated magnesium cone is ext emely
light but still ext emely stiff and effectively educes
esonances.
The ubbe su ound makes su e that no edge
esonances a e p esent.
The moulded metal basket of "high flow" type that
is acoustically t anspa ent and high p ecision since
the basket is shaped exactly due to moulding. This
makes su e that the basket is ve y stable and
efficiently educes esonances. The basket is
absolutely none magnetically, which cont ibutes to
a highe efficiency of the d ive .
A st ong magnet combined with the light cone
yields a high efficiency and a good t ansient
esponse.
Heavy coppe ings mounted above and below the
T-shaped pole piece educes non linea and
modulation disto tion and inc eases the ove load
ma gin.

The coppe plating of the top and bottom plates
along with a solid coppe phase plug imp oves the
heat conduction and thus cont ibutes to the high
powe du ability.
Gold plated te minals educe contact esistance
and se ves as anti-co osion.
La ge windows in the
basket both above and below
the spide educes sound eflection, ai flow noise
and cavity esonances.
Crosso er /
Binding post
We have chosen a -12 dB c ossove that has a fast
t ansient esponse and a minimum of phase
shiftings.
The connecto s a e gold-plated and of bi-wi ing
type so that you can connect to the amplifie with
double cables (bi-wi ing), o connect to two
amplifie s (bi-amping) fo fu the imp oving the
sound. The following coupling modes a e available:
1. Upper terminal + lower terminal (loops
present)
Default setting, the loudspeake is fed with the
enti e f equency ange.
Without the loop between uppe and lowe
te minal:
2. Upper terminal. The signal is only fed to the
tweete .
3. Lower terminal. Now the signal is fed to the
woofe only.
Preparations
Unpackning
Ca efully unpack the speake , and pay attention so
you don't b eak
anything. If possible, save the
ca ton box fo futu e t anspo tations. If the e
should be damage
on the loudspeake , please
contact you etaile .

Practice of sound / Installation and placement tips
This chapte contains common info mation on
loudspeake placement and installation.
Thi
s is gene al ules, so the e a e exceptions of
some ules
In which room do
you achie e the best
sound?
No matte how good the equipment is, in the w ong
listening envi onment it will inevitably sound bad.
The e a e some basic ules conce ning a p
ope
loudspeake installation:
Reflections
Ca pets, cu tains and soft fu nitu e abso b mid
ange and high f equency sound, and this is
p efe able. Big empty a ea, on the cont a y, eflects
it and p oduces ha d eflections that may lead to
blu y
dialogue. Apa t f om colou ing the sound,
also the pe spective of the sound will dete io ate.
Reflections in the oom can oughly be compa ed to
the eflections that yield ghost pictu es on a TV
sc een.
Amplification of bass
frequencies
A loudspea
ke that is placed nea a wall, ceiling o
floo will amplify lowe f equencies in a sometimes
not desi able way (since it may lead to an indistinct
sound ec eation). This amplification becomes even
mo e obvious if the loudspeake is placed nea a
co ne .
Thus, fo a sound as clea as possible, the
loudspeake should be placed at least 30 cm (about
12 inch) away f om the wall
Some const uctions a e made to be placed closed to
a wall.
Furniture
Be awa e that fu nitu e may vib ate and thus c eate
bad sound at loud bass.
Room dimension
Quad atic ooms o ooms whe e the length is
exactly twice as long as the width should be
avoided, since they may c eate unwanted
esonance.
Placement of the
subwoofer
The placement of the subwoofe
in the oom
d amatically affects the ove all f equency esponse
and sound level of the system. At low f equencies
the effect of the oom is st ong. Even a slight
change in the subwoofe 's location can make a
significant diffe ence in the f equency balance.
Patience and methodical expe imentation is needed
to find an optimal placement. The placement
affects the phase diffe ence between the main
loudspeake s and the subwoofe .
One basic ule is to place the subwoofe togethe
with o nea the f ont system (
especially impo tant
if the f ont loudspeake also p opagate bass
f equencies) as this will minimize the isk of phase
eliminations in the oom.

Page: 7
Cables
T y to keep them as sho t as possible. By its
elect ical pa amete s, a long conducto will have
a
bigge influence on the sound than a sho t one. It
may also wo k as an antenna and thus eceive
va ious signals that may become a constant noise in
an active subwoofe .
Make su e that all connections a e clean and not
oxidized. All connections should b
e mechanically
stable, both powe , signal and loudspeake cables.
Signal cables should be sepa ated f om othe
cables.
Front speakers
To get the best esult the f ont speake s should be
placed symmet ical in f ont of the listene . The
distance bet
ween the f ont speake s should be
a ound 80% of the distance to the listene . In othe
wo ds, the ecommended angle between the f ont
speake s should be 45°.
Why use 2
Subwoofer
The e a e mo e then one
benefits of having 2
subwoofe s instead of one.
The sound p essu e level will be highe .
Less dips and standing waves in the oom and a
bette f equency esponse in the oom (and on
sweet spot)
The need of powe is less, to each the same SPL as
with one subwoofe
Finally
Please emembe t
hat good sound is a matte of
taste, so you have to expe iment to obtain you
favou ite one.
We wish you best of luck!

Mounting and Connecting tips
Mounting
alternati es
No mally the XTZ 99.26 Cente
is placed nea a TV
set o a p ojecto sc e
en. The wall behind affect the
ep oduction of the speake and cha acte istics.
Please take you time to t y out the best placement.
Connect using the
correct phase
Always connect using the co ect phase, f om the
+-pole on the amplifie to the +-p
ole on the
loudspeake and co esponding fo minus (-).
If you by accident connect the othe way,
the e is no isk of damage. Howeve , the
sound will not be co ect, especially in the
lowe f equencies.
O erload
At high load du ing extensive time pe
iods, the e is
always the isk of ove loading the d ive and
amplifie .
All loudspeake s have a limited patience
fo high powe , so be ca eful not to play
ext emely loud and not to inc ease t eble
o bass settings to much.
By inc easing the bass o t eb
le f om 0 to
max you will inc ease the powe by about
16 times.
The initial playing
time
It takes about 50 to 100 hou of initial playing time,
fo the d ive to sound optimal. Du ing this time,
the speake may be used no mally.
Rotate tweeter
A Cente speake can both be used as standing o
lying down. The tweete can the efo e
be otated 90
deg, so it can fit the need of the owne .

Room Tuning -
Mechanical
adjustment of the
boundary frequency
By using the supplied bass plugs in the bass eflex
gates, you can alte the lowe bounda y f equency
on the XTZ 99.26 Cente .
Also the t eble level may be adjusted, which allows
you to pe fectly alte the sonic to fit the oom,
equipment and you own taste.
Closed gate
With the bass plug mounted in the bass eflex gate,
the cabinet is closed and the loudspeake ope ates
as a closed const uction which yields a mo e "tight"
bass ep oduction.
Bass reflex
With no plug p esent in the gate you have a highe
bass level and the lou
dspeake is capable of
handling lowe f equencies.
This setting also depends on the size and
shape of the oom, and also on you own
taste, so please has patience when t ying
out you p efe ed setting.
Le el adjustment in
the treble range
In the t e
ble ange the level is adjustable in fou
diffe ent modes using the supplied loop connecto .
Level adjustment in the t eble ange:
Mode 1/ 0dB
In this mode the sound is neut al with a
flat f equency esponse.
Mode 2/ +3dB
In this mode the t eble level is inc ease by 3dB.
Mode 3/ -2dB
In this mode the t eble level is dec eased by 2dB.
Mode 4/ -4dB
In this mode the t eble level is dec eased by 4dB.
