The basket

The GRAPHIC TT1 mid/bass ope­rates in a powder coated die-cast
Euro-DIN aluminium basket. With
its 166 mm diameter and a moun­ting depth of just 64 mm it fits
the usual range for metal
baskets. The GRAPHIC PRO Set
includes special safety screws
that avoid twisting the basket
during mounting.

For the control of the voice coil
temperature even under great
loads, the basket is provided
with a venting system. To keep
the connectors in a steady posi-

tion, a specially designed part
forms a unit with the basket.

The terminals

The TT1 is supplied with 24 carat
gold-plated connectors with fine
threads.

A special feature is the
+/- mark cut into the screw head.
It allows tight fastening with a
Torx screw driver.
The fastening of the connectors
to the basket is short-circuit­proof and twisting free due to
special plastic sleeves. They pre­vent the connectors from being
wrenched when connecting the
cables.

The driver

The powerful 100 mm magnet
system with its lathed pole plate
is vented by 6 holes. They are
protected by gold-plated alumi­nium meshes.

Together with the solid stainless
steel phase plug they ensure the
cooling of the 37 mm voice coil.
The labelling as well as the indi­vidual serial number on the black
polished pole plate is applied
with a laser.

The diaphragm

The „Graphic“ diaphragm

consists
of high rigid polymethacrylimide
foam which is normally used as
core material in high-strength
sandwich constructions (e.g. for
airbus A340 tail fins or motor
racing car parts). The upper and
lower layer consists of a lamina­ted and blackened glass fibre
fleece. In between you find the
layer made of polymethacrylimide
foam. This „sandwich“ is shaped
at a temperature of 300° and
reaches an exceptional stability
and stiffness.

„Creating perfect loudspeaker systems is a matter of craft and pre­cision, to compose their pureness and musicality is a fine art.
Bringing both together is our tradition and makes up the result of
our work.“ (Heinz Fischer)

BRAX GRAPHIC PRO Tweeter HT1

The housing

The GRAPHIC HT1 operates in a
two-part lathed solod stainless
steel housing. It eliminates 350
times more heat than a conven­tional tweeter housing. The front
plate is shaped like a wing, which
is the perfect design for superb
radiation surface characteristics
of the speaker.

Hidden fastening is no problem
thanks to a thread on the back
part of the housing. The hand

lathed cable terminals are suita­ble for loudspeaker cables up to
2,5 mm

.

The driver

The 25 mm HT1 voice coil is dri­ven by a drilled neodyme magnet
system. The 6 holes in the pole
plate not only ensure the coup­ling of the tweeter to the volume,
they also eliminate heat.
The coupled, dampened volume
of the HT1 achieves a resonance
frequency of 730 Hz.

The diaphragm

The glass dome of the tweeter is
manufactured in 5 separeate pro­cesses. The first involves a glass
fibre nonwoven mat that is
immersed in a bath of special
resin. The impregnated material
is then also compressed in a heat
press and baked in a mould to
give it its final shape. The result
is a yellow, paper-thin, mesh like
dome. In order to render it air­tight, it is coated with a clear
dispersion which also provides it

with a glossy finish. The two lay­ers are permanently bonded to
each other by a type of artificial
ageing process using UV light,
which also gives the dome its
golden colour.

After cutting the dome is bonded
to a supronyl edge consisting of
two 65µ thick layers of polyami­de.

The frequency crossovers

The two crossovers were develo­ped especially for the TT1 and

HT1. They make the BRAX GRA­PHIC PRO a perfectly tuned and
harmonic sound system of the

reference class. A balanced sound
in any car and at any volume is
made possible by sophisticated

features such as individual high
pass adjustment.

BRAX GRAPHIC 6 High-End Loudspeaker System

The GRAPHIC 6 system is the kee­ner-priced version of the top-end
GRAPHIC PRO system. A lot of
details are taken from its „big
brother“ and it benefits from a lot
of basic materials that came with
the exploration of the GRAPHIC
PRO. The result is a truly excep­tional system at an unbeatable
price/performance ratio.

The baskets and the connectors
of the TT 6 and the GRAPHIC
PRO TT1 are identical and have
the same

advantages. With its 80

mm mag

net system and a lathed

pole plate with venting holes the
driver is different from the PRO
system. It cools the 25 mm voice
coil. Labelling and individual
serial numbers are lasered on the
glossy black pole plate.

The „Graphic“ material used for
the diaphragm makes the TT6 an
exceptional loudspeaker of its class.
In spite of its compact design it is
very well able to give lowest fre­quencies a clear contour.
The HT6 tweeter also has a glass
dome bonded to a supronyl edge.
The ferrofluid cooling of the voice
coil guarantees optimum heat eli­mination at high power output.

A sophisticated 2-way frequency
crossover was designed in order
to enable harmonic tuning of the
speakers by using selected and
high quality components. Besides
its technical advantages you find
costly parts such as gold plated
connectors which make this pro­duct a feast for the eyes.

GRAPHIC PRO
loudspeaker system

These capacitors are an exclusive
AUDIOTEC FISCHER development
for BRAX. Its outstanding sound
performance is basically achieved
with a special

induction-free win­ding technology:
Two capacitor windings are inter­leaved so that their inductancies
eliminate each other. These two
windings are connected in series
so it needs four times more mate­rial than other capacitors.

Special gold-plated acrylic cases
prevent microphonic effects, the
polypropylene film used for these
high end capacitors has exceptio­nally low loss characteristics. The

resulting listening experience
more than justifies the effort that
was invested.: No other capacitor
delivers such a perfect spatial
sound with finest musical nuan­ces.

No matter where these capacitors
are used - as a coupling capacitor
in a CD player or amplifier or in a
loudspeaker crossover - there is
always the same surprising and
impressive performance as well
as significant enhancement.
