Congratulations

Thank you for selecting STUDIODRIVER components. Manufactured in
Stuttgart, Germany, technical innovations and high-tech processes are
employed throughout our manufacturing process to help ensure many years
of musical enjoyment. These drivers are the end result of our commitment
to the PRECISION REPRODUCTION of PURE MUSIC WITHOUT LIMIT.

SERVICE:

Do not attempt to service STUDIODRIVER products yourself. Performing
exploratory surgery on your audio equipment yourself will void the warranty .
Many parts of your STUDIODRIVER gear are custom built to our specifications.
Our factory parts are not made available to anyone else nor are they for
sale. Our goal is to make sure that your STUDIODRIVER product will always
sound as good as the day it was purchased. Contact your authorized dealer
about obtaining any warranty service through STUDIODRIVER. (See Warranty
inside back cover.)

CAUTION!

The extended use of a high powered audio system may result in hearing
loss or damage. While STUDIODRIVER products are capable of “Concert Level”
volumes, they are also designed for you to enjoy at more reasonable levels,
all of the sonic subtleties created by musicians. Please observe all local
sound ordinances.

INTRODUCTION

Your new STUDIODRIVER component set is part of an exciting line of
loudspeakers. They are the definitive result of years of research and
development, realized by the same engineering team charged with designing
audiophile quality speaker systems for a select group of high performance
German automobiles, working hand in hand with our own award-winning
engineering staff. Like all STUDIODRIVER products, they reflect our
commitment to strive for Precision Reproduction of Pure Music Without
Limits!

STUDIODRIVER components employ cutting edge aluminum curvilinear cones
to eliminate unwanted resonance inherent in conventional metal cone
designs. Our use of an ultra-light and rigid aluminum cone allows a dramatic
increase in sound velocity, or what we call "sonic-speed". This means
impulses from the voice coil travel though the aluminum cone nearly four
times faster than typical paper cones. Even more significant than pure speed,
music is reproduced in a way that is clearly more dynamic, precise, detailed
and distortion-free. In other words...sound reproduction has never been more
REAL. Always respected in the audio community for its ability to dissipate
heat efficiently, aluminum cones assure excellent cooling of the voice coil,
resulting in increased power handling and reduced power compression.

STUDIODRIVER loudspeakers also feature a unique copper cap over the pole
piece, which effectively alters the magnetic field around the voice coil,
minimizing the effect of "eddy currents", this results in a more controlled,
linear impedance and phase response.

The NT-1 25mm high frequency driver features a titanium dome for the perfect
combination of superior strength and ultra-light weight.

Note: STUDIODRIVER Component midrange and midbass loudspeakers employ
pure aluminum cones. They can be damaged if they are not handled with care.
Care should be taken during installation to avoid damage to the cones. Physical
damage to the cones will not be covered under warranty.

As always, STUDIODRIVER recommends that your component speakers be
installed by an Authorized Dealer.
