Bass Drivers
The foundation of the TAD Reference One loudspeaker is the bass
drivers, as shown in Figure 3. The driver cones are constructed
from a tri-laminate of front and rear-woven aramid fibers that
sandwich a foamed acrylic core. This provides enormous strength
to the cone in order to resist any flexing due to the high forces
exerted during loud bass passages.
To achieve high drive linearity, the motor structure employs short
coil and long gap geometry, Faraday shorting rings, and a novel
flux path for even lower distortion. Combined with advanced
spider and multi-roll surround design, the bass driver has over
26 mm (1.02 in.) of linear drive capability, as shown in Figure 4.
