Introduction
Introduction 93.21 offers some possibi ities, so in order to uti ize
your new oudspeaker in the best way; you shou d
carefu y read through this manua before using the
oudspeaker for the first time. It may take some
patience in order to make the oudspeaker sound
optima .
If you have no previous experience of these kinds of
insta ations, or if you have any questions, fee free
to contact our free of charge support and we wi
he p you. (See further under the heading of
Support on the ast page of this manua ).
About 93.21 MKII

either as frontspeaker (on a stand for examp e) or a
bookshe f speaker.
About XTZ
P ilosop y Our reference and starting point is to recreate a
natura sound, but a so in respect to the fact that
acoustics a ways is a matter of taste
XTZ Goals To provide t e optimal relation between
price, performance and quality on t e
market.
Our concept:
- To produce the perfect compromise.
- Cost-effective manufacturing at a arge sca e.
- The qua ity of our products is more mportant than
the marketing.
- Reduce the number of midd emen.

Technical presentation
Cabinet design The cabinet is constructed with a narrow baff e, an
advantage in terms of sonic performance as it adds
to the stabi ity. This effective y reducesresonances.
The cabinet is made from 21 mm MDF which offers
good sonic qua ities and is in tota ensures a very
stab e construction.
Tweeter driver We have chosen a 1” si k-made soft dome tweeter
which provides superior transient response and a
very f at frequency response without resonances.
Woofer/midrange-driver After eva uating a arge number of drivers from
different manufacturers we se ected a driver which
is very competent.
For woofer/midrange we decided on a 6,5" so id
coated driver which gives a smooth extended
frequency response with a contro ed ro off.
The driver is made up of so id coated paper which
has good sound qua ities, high strength and ow
weight.
The surface treated cone is extreme y ight but sti
extreme y stiff and effective y reduces resonances.
The rubber surround makes sure that no edge
resonances are present.
The mou ded meta basket of "high f ow" type that
is acoustica y transparent and high precision since
the basket is shaped exact y due to mou ding. This
makes sure that the basket is very stab e and
efficient y reduces resonances. The basket is
abso ute y non-magnetic, which contributes to a
higher efficiency of the driver.
A strong magnet combined with the ight cone
yie ds a high efficiency and a good transient
response.

Crossover/Bindings We have chosen a -12 dB crossover with a fast
transient response.
The go d p ated connectors are sing e wired and
offer the possibi ity to connect the amp ifier using
banana p ugs, fork-or cab e into the speaker
termina .
The tweeter is adjustab e in 2 eve s.

Preparations
Unpacking Carefu y unpack the speaker, and pay attention so
you don't accidenta y break anything. If possib e,
save the carton box for future transportations. If
there shou d be damage on the oudspeaker, p ease
contact your retai er.

Practice of sound Installing and placing tips
This chapter contains common information on
oudspeaker p acement and insta ation.
In w ic room do you
ac ieve t e best sound?
No matter how good the equipment is, in the wrong
istening environment it wi inevitab y sound bad.
There are some basic ru es concerning a proper
oudspeaker insta ation.
Reflections Carpets, curtains and soft furniture absorb
midrange and high frequency sound, and this is
preferab e. A arge empty area, on the contrary,
ref ects it and produces a hard sound that may ead
to a b urry dia ogue. Apart from co ouring the
sound, a so the perspective of the sound wi
deteriorate.
Amplification of bass
frequencies
A oudspeaker that is p aced near a wa , cei ing or
f oor wi be amp ified in the ower frequencies in a
sometimes not desirab e way (since it may ead to
an indistinct sound recreation). This amp ification
becomes even more obvious if the oudspeaker is
p aced near a corner. Thus, for a sound as c ear as
possib e, the oudspeaker shou d be p aced about
30 cm (about 12 inches) away from the wa .
However, there are exceptions from this ru e. For
some type of wa s / rooms it may be advantageous
to p ace the oudspeaker c oser to the wa .
Furniture Be aware that furniture may vibrate and thus
createbad sound at oud bass
Room dimensions Quadratic rooms or rooms where the ength is
exact y twice as ong as the width shou d be
avoided, since they may create unwanted
resonance.
Placing t e loudspeakers How the oudspeakers are p aced towards the
istener is of great importance
T e front speakers For stereo istening the oudspeakers shou d be
p aced symmetrica y in front of the istener. The
distance between the oudspeakers shou d be about
80% of the distance between the istener and one
oudspeaker, or put in another way: the ang e
between the oudspeakers, as seen from the istener,
shou d be about 45 degrees. This means for examp e
that if the distance between the oudspeakers is 2
meters, the istener shou d be p aced 2.5 meters
from the oudspeakers.
6

Angling? Either you can have the oudspeakers ang ed in
towards the istener or you can have them directed
straight ahead. Some oudspeakers sound better
when ang ed, but this may a so depend on
ref ections from the side wa s. By ang ing the
oudspeakers inwards, you decrease unwanted
ref ections and thus you get a better stereo
perspective.
T e correct eig t If the oudspeakers are sma , they shou d be p aced
on stands or ti ted so that they are on the same
eve as the ears.
Cables Try to keep them as short as possib e. By its
e ectrica parameters, a ong conductor wi have a
bigger inf uence on the sound than a short one. The
subwoofer cab e shou d be shie ded, to avoid noise.
Make sure that a connections are c ean and not
oxidized. A connections shou d be mechanica y
stab e, both power, signa and oudspeaker cab es.
Signa cab es shou d be separated from other cab es.
Finally P ease remember that good sound is a matter of
taste, so you have to experiment to obtain it.
We wish you the best of uck!

Mounting and connecting tips
Mounting alternatives The wa behind and the wa beside the oudspeaker
have inf uence on both the bass eve and the bass
characteristics, so p ease be patient and try different
distances to the rear and side wa s.
Connecting using t e
correct p ase
A ways connect using the correct phase, from the +-
po e on the amp ifier to the +-po e on the
oudspeaker and corresponding for minus (-).
If you by accident connect the other
way, there is no risk of damage.
However, the sound wi not be
correct, especia y in the
ower frequencies.
Overload At high oad during extensive time periods, there is
a ways the risk of over oading the driver and
amp ifier.
A oudspeakers have a imited
patience for high power, so be
carefu not to p ay extreme y oud
and not to increase treb e or bass
settings to much.
By increasing the bass or treb e from
0 to max you wi increase the power
by about 16 times.
T e initial playing time It takes about 50 to 100 hour of initia p aying time,
for the driver to sound optima . During this time,
the speaker may be used norma y.

Sound settings
Room Tuning –
Mec anical adjustment
of t e boundary
frequency
By using the supp ied bass p ugs in the bass ref ex
ports, you can a ter the ower boundary frequency
on the 93.21.
A so the treb e eve may be adjusted, which a ows
you to perfect y a ter the sonic to fit the room,
equipment and your own taste.
Closed port
With the bass p ug mounted in the bass ref ex port,
the cabinet is c osed and the oudspeaker operates
as a c osed construction. This yie ds a more ”tight”
bass reproduction.
Bass reflex
With on y one p ug in the port, you get deeper bass
response than a c osed box.
With no p ug present in the ports you obtain the
highest bass eve .
These settings a so depend on the
size and shape of the room, and a so
on your own taste, so p ease have
patience when trying out your
preferred setting.
Level adjustment -
Treble
The treb e range can be adjusted to 2 different
settings.
Level adjustment in t e
treble range
In the treb e range the eve is adjustab e to two
different modes using the switch on the back of the
speaker.
Mode 1, 0 dB
In this mode the sound is neutra with a f at
frequency response.
Mode 2, -2 dB
In this mode the treb e eve is decreased by -2 dB.
Crossover / Terminal We have chosen a -12 dB crossover fi ter with a fast
transient response and minimum phase shiftings.
The go d p ated connectors are sing e wired and
offer the possibi ity to connect the amp ifier with
banana p ugs, forks or pure cab e into the speaker
termina .
