STRADIVARI SPEAKERS

INTRODUCTION

Congratulations on choosing Stradivari Speakers. Your speakers have been hand-

crafted from the finest parts and materials. The Stradivari Speakers utilize proprietary

Cello circuitry and are designed to perform for decades of musical enjoyment.

Until now, music lovers had to choose between speakers with a high degree of
transparency and speakers with punch and dynamic range. Some products,
attempting to do both, have achieved neither goal. The Stradivari Series from Cello
combines transparency with punch and dynamic range, as well as superb imaging,
elegant styling and exceptional reliability.

Please read this manual carefully. If you have any questions, contact your Authorized
Cello Supplier, or call Customer Service at the factory. It is our wish to assist you in
every way, now and in the future.

STRADIVARI SPEAKERS

PRODUCT CONCEPT&DESCRIPTION

Concept Because of Cello's work with major record companies and

mastering laboratories, we know that stability (no performance
drift), reliability (no down time), and flexibility (ability to play
all kinds of music) are essential qualities for professional
monitor speakers. Yet, speakers having these attributes
generally lack natural tonal qualities. Studio engineers have
been forced to live with such speakers because they cannot

accept the power handling limitations and other problems of
more sonically refined speakers. At the same time, in order to
enjoy more natural tonal qualities, music lovers at home have
been forced to accept limitations in stability, power handling,
dynamic range and reliability. The Strad series is a solution for
both studio professionals and home listeners who want it all.

Construction

All Strad models are designed and built with the same high
level of quality, construction and component parameters. With

design considerations for cabinet size and driver array, the
hand-finished drivers, crossover boards, wiring and other
materials used in all Strad products are of the same high level of
quality, construction and component requirements and
parameters. The difference between them is the height of the
cabinet and the number of drivers and crossover boards. A
comparison can be made to string instruments and pianos,

which are made with the same quality but are available in
various sizes for different requirements.

Strad models feature a vertical in-line array of mid and high
frequency drivers on a relatively narrow front panel. On each
floor standing model cabinet this front panel is angled in at 15

degrees toward the listening position, so the sides of the speaker

stay parallel to side and rear walls, while the face is positioned

at the correct angle for optimum performance.

Heavy duty brass bolts are provided for tri-wired speaker

connections. Special harnesses of Cello Strings 3 Litz speaker

cable are recommended for termination to the power

amplifier(s).

Finish

Music

Strads are available in either black piano or rosewood finish on
standard order. Other custom finishes may be available on

request. Black, acoustically-transparent grills are provided.

Strads are designed to complement the finest interior
appointments and are, themselves, handmade works of art.

First, play a recording of a delicate instrument such as a
harpsichord. Hear how the Strad reproduces the natural tone,
subtleties, complex harmonics, exact attacks, and room
ambience rather than impressing you as a large speaker. The
clarity is there together with the body of the instrument. There
is a presence between the speakers, as there would be in life if
the artists were there.

Second, play a recording of human voice or voices. It sounds
like human beings making music. Again, the Strad resists the

need to impress you with its size and allows the music to
provide the impression.

Third, listen to the most dynamic recording of a symphony
orchestra playing the Firebird, or a jazz band such as Count
Basie.

Strad Grand Master

In concert with Cello electronics and cables, the Strads spring to
life, reproducing from triple pianissimo to triple fortissimo with
complete ease. If you know the recording, you may find it hard
to believe it is the same one because it now sounds so full,
uncompressed, and real.

Now you realize that with all kinds of musical recordings the
Strads give you what the musicians intended: the full tone,
ti

mbre, size and depth of the music. This enables the musical

message to come through intact.

Like the concert grand, the Grand Master is the largest Strad
model. Elegant in dimension, each Grand Master is a towering

cabinet with eight tweeters, eight midranges, and two 12"

woofers. These drivers enable the Grand Master to move a great

quantity of air very quickly, achieving not only very low

distortion but a staggering 127dB SPL peak capability.
