Introduction - Acoustic Technology
Introduction
- from the latin Pristinum‘,: pure, uncorrupted, original condition.
Pristinum is created with the intention of allowing the soul of music to reveal itself in all its original form,
uncorrupted by today’s mediocre products and marketing trends.
It is a representation of state-of-the art loudspeaker technology and fine-tuning – a synergy between
“technology and art”; resulting in “accuracy and musicality”.
Accuracy is achieved when a system remains true to the intent of the recording. This is achieved by
having very low levels of harmonic distortion with minimum time smearing and coloration.
Musicality flows when we retain the emotional vigor of the musical event. This is achieved by a
tweaking and fine tuning process. Instead of designing a product solely by measurement and theory,
we spent hundreds of hours on trial and error methods and adding the “human touch”.
The result is a speaker system which can give the listening experience the emotional excitement and
realism of the actual musical event.

Tweeter - TW2701
TW2701 is a high resolution, wide bandwidth
fabric dome tweeter using state-of-the art
Scandinavian Technology.
The motor system houses high grade
neodymium magnets and an optimized tuned
chamber. The entire motor system is built as
one resulting in low structural vibration and
resonances.
Housed in the chamber are damping felt
materials and acoustic wool, absorbing the
backwave reflections and damping the
impedance at resonance. The free-air
resonance of this tweeter is a low 1,080 Hz.
For non-custom installations, the wedge
mount kit allows direct mounting onto dash
or pillars without any major modification to
the vehicle. With two off axis angles to
choose from, the ideal dispersion pattern can
be achieved.

Mid-Woofer - PW165
PW165 is a polypropylene cone midbass drive unit with a
powerful and linear motor system.
The specially selected low loss butyl surround mated with a
flat spider design results in optimum suspension tuning for
fast impulse response and deep low frequency
reinforcement.
The copper clad aluminium voice coil increases power
handling, bandwidth and lowers inductance. The voice coil is
surround by powerful barium ferrite magnets keeping the
flux energy concentrated at the magnetic gap.
The result is a wide bandwidth mid-woofer capable of very
large linear excursion. (8mm p-p).
The stamped steel basket is coated with anti-resonance
material which increases rigidity and lowers the resonant
frequency.

Crossover - XP 6.1
Featuring Advanced Serial Network Topology
(AS Net)
The XP-6.1 crossover network not only acts as a
filter, but minimizes phase errors and lobbing
problems at the crossover region. This is achieved
through using AS net topology which whereby the
tweeter and mid-woofer are cascaded with reactive
components. As a result, not only does the response
achieve great linearity and minimal phase problems,
but the stage is pushed far into the dash instead of
being forward or in your face. This is the world’s
first product to use such a technology in car
audio.
Audiophile grade capacitors are custom made in
Germany to achieve the most neutral sound
character without adding any grain or distortion to
the signal.
Low DCR, high purity copper (diameter = 1.4mm) is
used for the air core inductors to achieve fast
impulse response and minimum time smearing.
Precision attenuation circuits are used for 8 step
tweeter level reduction. The secondary function is
dampening the impedance so the user can adjust
brightness or mellow sound just by changing the
jumper settings.

Mid-Woofer - PW110
The PW110 is a versatile polyproprene/paper midbass
driver that has an amazing 6mm P-P linear excursion.
The low loss rubber surround and spider results in
extremely low energy storage. A bullet shaped phase
plug reduces compression, resonance problems in the
pole region and increases power handling. It can either
be used as 4" midbass in 2-way setups or dedicated
midrange in 3-way. It will fullfill minimum phase
condition when custom into A-pillar with optimal
position and implementation of AS net passive
crossover, ideal for competition systems
