TAD Reference One Owner's Manual
TAD History
Founded in 1975, Technical Audio Devices (TAD)
has continued to stand at the frontier of cutting-edge
sound technology, maintaining a well-established
tradition of creating high performance speakers for
professional use. TAD products are designed, crafted,
and produced with strict adherence to the most
rigorous standards demanded by musicians and
professional audio-system designers around the world.
TAD loudspeaker components are found in studio
monitors, sound reinforcement systems, public
address and concert hall speakers, cinema theater
audio systems, and many other applications that
require the highest-quality sound reproduction.
With this high standard of quality, world-class
recording studios rely on TAD components for
original recordings and digital remastering of audio
performances. In recent years, TAD has met the
demand for high-quality home audio speakers by
delivering world class audio components that carry the
TAD pedigree into the home.
TAD Reference One Description
The TAD Reference One loudspeaker is a
breakthrough product for the home audio market,
and represents the culmination of over 30 years
experience in developing class-leading loudspeakers
for the professional studio monitoring environment.
Central to the performance of the TAD Reference
One loudspeaker is the Coherent Source Transducer
(CST), a concentric unit featuring TAD's unique
beryllium-diaphragm design. Beryllium is used for
both the tweeter dome and the midrange cone, to
provide a point source radiator covering the frequency
range from 250 Hz to 100 kHz.
The CST is supplemented by dual 25 cm (10 in.) bass
drivers enclosed in structurally inert cabinet. The
result is a very wide-band, resonance-free monitor
loudspeaker of the highest quality.
About The Manual And Warranty
To obtain optimum performance from this product,
please carefully read the remaining pages of this
owner's manual, along with manuals of other
components in your system. To register for warranty
support, please fill out and mail the enclosed warranty
card.

Beryllium Diaphragms
Each TAD Reference One loudspeaker features
proprietary beryllium-manufacturing technology for
the midrange and tweeter diaphragms. The lightest
and most rigid metal available for diaphragms,
beryllium performs with strength and damping
characteristics unmatched by any of the materials
currently used in high-end audio loudspeaker
manufacturing, as shown in Figure 1. Beryllium's
combination of light weight and exceptional strength
enables diaphragm resonance to be pushed far beyond
the operating band of its drive units. This produces
near-perfect piston behavior in the speakers, resulting
in cleaner sound and greater accuracy of reproduction.
CST
The heart of the system is the Coherent Source
Transducer (CST), shown in Figure 2. The tweeter
diaphragm is mounted concentrically within the apex
of the midrange cone and provides a point source of
sound from 250 Hz to 100 kHz. It is time coherent,
due to the shallow midrange-cone profile made
possible by the superior strength of beryllium, and
produces a superbly-controlled radiation pattern. CST
ensures a perfect spectral balance between the direct
and reflected sounds that arrive at the listener's ears,
providing a more consistent sound throughout the
listening room and improved imaging capability.
