TAD Reference One Owner’s Manual
CST Mounting Construction
The CST driver is mounted into an extremely firm
enclosure that features a headboard specially formed to
optimize the sound emitted from the driver. To
further enhance the performance, ISO-Drive
technology is used to mechanically isolate the CST
driver from its mounting. This greatly reduces the
mechanical energy that is the source for enclosure
vibration, resulting in reduced delayed resonances and
improved resolution of fine detail.
Bass Enclosure Construction
The enclosure of the TAD Reference One's bass
drivers features a frame of 21 mm (0.9 in.) thick
laminated birch plywood supported by a CNC
processed plywood back board “spine” up to 137 mm
(5.7 in.) thick, clad with 50 mm (2 in.) curved side
panels created by high-frequency heating. The bass
reflex port was modeled after the design concept of the
TAD compression driver and horn, resulting in the
reduction of wind noise for clear, deep bass. In order
to fully realize the drive unit's potential, the drivers are
securely mounted to the enclosure and the enclosure is
slanted at a four-degree tilt back, optimizing the unit's
center of balance. The 150 kg (330 lb) mass of this
system produces a correspondingly powerful bass
sound that is both clean and subtle. The teardrop-
shape both reduces sound diffraction, allowing for
excellent acoustics, and also serves to eliminate
unnecessary resonance and internal standing waves.

Crossover Networks
The crossover networks use only the finest
components. Air cored coils, noninductive resistors,
and film capacitors in the signal path are all carefully
chosen and optimized for the CST driver to provide
the greatest transparency to the signal. The bass drivers
use laminated steel-core inductors for highpower
handling and low saturation. All components are built
on high-grade, glass-epoxy, printed circuit boards with
thick copper traces to ensure stability and repeatability
of performance.
Enclosure Finish
The enclosure features rare, elegant natural wood that
is treated with a transparent finish. Its surface has a
beautifully polished mirrored finish, the result of the
meticulous, painstaking work of skilled craftsmen.
This product is designed to elicit the full potential
of the natural wood used in its enclosure. Note
that the color and pattern of the wood is slightly
different for each unit.
