Technical presentation

Cabinet de ign

The cabinet is constructed with a narrow baffle, an

advantage in ter s of sonic perfor ance as

it adds

to the stability. This effectively reduces

resonances.

The cabinet is ade fro 21

MDF which offers

good sonic qualities and is

in total ensures a very

stable construction.

Tweeter driver

We have chosen a silk- ade soft do

e tweeter

which provides superior transient response and a

very flat frequency response without resonances.

Woofer/ mid range

driver

For the woofer/ idrange we decided to use a 6,5"

solid coated driver with a s ooth extended

frequency response and a controlled roll off effect.

The driver is ade fro solid coated paper offering

good sonic qualities, a high strength and low

weight.

The surface treated cone is extre ely light but

still

stiff and effectively reduces resonances.

The rubber surroundi

ng helps suppressing edge

resonances.

The etal basket is a "high flow" type that is

shaped exactly due to the precise oulding process.

This akes sure that the basket is very stable and

efficiently reduces resonances. The basket is

solid

and stable.

strong agnet co bined with the light cone

ensures a high efficiency and a good transient

response.

Cro over / Binding

po t

We have chosen a -12

dB crossover with a fast

transient response.

The gold plated connectors are single wired

and

offer th

e possibility to connect the a plifier using

banana plugs, fork-

or pure cable into the speaker

ter inal.

The tweeter is adjustable in 2 levels

Preparations

Unpacking

Carefully unpack the speaker, an

d pay attention so

you don't accidentally break anything. If possible,

save the cardboard box for future transportations.

In case there are any visible da ages on the

loudspeaker, please contact your retailer.

Practice of sound Installing and placing tips

This chapter contains co on infor ation

about

loudspeaker installation and place ent.

In which room do

you achieve the be t

ound?

No atter how good the equip ent is, in the w

rong

listening environ ent it will inevitably sound bad.

There are so e basic rules concerning a proper

loudspeaker installation:

Reflection

Carpets, curtains and soft furniture absorb id

range and high frequency sound, which is

preferable. Big e

pty area reflexes the sound which

ay lead to a blurry dialogue

. Apart fro colouring

the sound, the perspective of the sound will

deteriorate. Reflections in the roo can al ost be

co pared to the reflections that cause ghost

pictures on a TV screen.

Amplification of ba

frequencie

A loudspeaker placed near a wall, ceiling or directly

to the floor will be a plified in the lower

frequencies in a so eti es not desirable way (since

it ay lead to an indistinct sound reproduction).

This a plificatio

n beco es even ore obvious if

the loudspeaker is placed near a corner. In order to

obtain a sound as clear as possible, the loudspeaker

should be placed about 30 c (about 12 inches)

away fro the wall.

However, there are exceptions fro this rule. For

so e type of roo s it ay be advantageous to place

the loudspeaker closer to the wall.

Furniture

Be aware that so e furniture ay vibrate and

cause interference.

Room dimen ion

Quadratic roo s (or roo s where the length is

exactly twice a

s long as the width) should be

avoided, since they often create unwanted

resonances.

Placing the

loud peaker

The way the loudspeakers are placed towards the

listener is of great i portance.

The front peaker

For stereo listening the louds

peakers should be

placed sy etrically 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 fro the

listener, should be about 45 degrees. This eans

for exa ple that if the distance between the

loudspeakers is 2 eters, the listener should be

placed 2,5 eters fro the loudspeakers.

Toe-in peaker

Either you can have the loudspeakers angled in

towards the listener or you can have the directed

straight ahead. So e loudspeakers sound better

when angled, but this ay also depend on

reflections fro the side walls. By angling the

loudspeakers inwards, you decrease unwanted

reflections and you will

in the sa e ti e have a

better stereo perspective.

The correct height

If the loudspeakers are s all, they should be placed

on stands or tilted so the

sound in the best way

reaches your ears.

Cable

Try to keep the cables as short as possib

le. By its

electrical para eters, a long conductor will have a

bigger influence on the sound than a short one. It

ay also work as an antenna and thus receive

various signals, which ay beco e a constant noise

in an active subwoofer.

Make sure that all con

nections are clean and not

oxidized. All connections (both signal and speaker

cables) should be echanically stable. Signal cables

should be separated fro other cables.

Finally

Please re e ber that good sound is a atter of

taste, so you have to experi ent to obtain it.

We wish you the best of luck!

Mounting and Connecting tips

Mounting

alternative

The wall behind and the wall beside the

loudspeaker have influence on both the bass level

and the bass characteristics, so take your ti

e, be

patient and try different distances to the rear and

side walls.

Connect u ing the

correct pha e

Be aware of the correct phase, fro the + pole on

the a plifier to the + pole on the loudspeaker and

corresponding for inus (-).

If you accidently

connect the other way,

there is no risk of da age. However, the

sound will not be correct, especially in the

lower frequencies.

Overload

At high load during extensive period of ti e, there

is always a risk of overloading the driver as well as

the a plifier.

All loudspeakers have li ited

high power

patience, so be careful not to play

extre ely loud.

By increasing the bass or treble fro

average level to axi u it will increase

the power by about 16 ti es.

The initial playing

time

It takes a

bout 100 hour of initial playing ti e, for

aking the driver to sound opti al. During this

ti e, the speaker ay be used nor ally.

Sound settings

Room Tuning -

Mechanical

adju tment of the

boundary frequency

By using the supplied bass plugs in

the bass reflex

ports, you can alter the lower boundary frequency

of the XTZ 93.21.

Also the treble level ay be adjusted, which allows

you to perfectly alter the sonic character to fit the

roo and your equip ent.

Clo ed port

With the bass plug oun

ted in the bass reflex port,

the cabinet is closed and the loudspeaker operates

as a closed construction. This provides a tight bass

reproduction.

Ba reflex

With no plug present in the ports you obtain a

higher bass level and the loudspeaker is capable

handling lower frequencies.

With only one plug in the gate, you get the deepest

possible bass response.

These settings also depend on the size and

shape of the roo and of course, it’s all

about your own taste, so please take your

ti e and have pati

ence when trying out

your preferred setting.

Level adju tment in

the treble range

In the treble range the level is adjustable in two

different odes using the link on the back of the

speaker.

Mode 1: 0dB

In this ode the sound is neutral with a

natural,

flat frequency response.

Mode 2: -2dB

In this ode the high frequency level is decreased

by -2dB.

Cro over/Terminal

We have chosen a -12

dB crossover filter with a fast

transient response and ini u phase shiftings.

The gold plated

connectors are single wired and

offer the possibility to connect the a plifier with

banana plugs, forks or pure cable into the speaker

ter inal.
