THREE NEW LINES OF INNOVATIVE DRIVERS
This tweeter is an exquisite combination of state-of-the-art
mechanics and meticulous tooling. Listeners will enjoy all the nuances
of higher-frequency harmonics brought out by their new TZ2900.
Extensive audio simulations based on a number of different horn
prototypes (approximately 40 different horn shapes were studied)
enabled us to develop a new tweeter profile that considerably reduces
the directivity of the high frequencies when listening away from the
centerline.
The new TZ2900 tweeter horn, whose form was modeled through
extensive computer simulations, presents the ideal profile in relation
to its dome’s mechanical and acoustic characteristics. This new horn
affords the new TZ2900 tweeter an extremely reduced directivity above
15 kHz.
We also added a counter-cap to the motor in order to limit the distortion
at the low end of the tweeter’s tonal spectrum. This cap contains a
duct lined with damping material that reduces reflections in the back
waves. This duct is made of titanium, a metal that provides an excellent
rigidity-to-weight ratio.
Located just in front of the dome is the phase plug, which has been
carefully designed in order to limit the distortion and regulate the
upper end of the sound spectrum. Computer simulations were used to
find the best designs for these pieces, which were then systematically
tested using our rapid prototyping system. The result is a tweeter that
is practically free of distortion.
The tweeter provides an exceptionally smooth and fluid musical quality
while ensuring accurate reproduction at realistic dynamic levels..
