The AMT Tweeter
While the high frequency drive unit in most speaker systems
is typically designated the “superstar” player, long experi-
ence has shown the Gryphon engineering crew that a far more
balanced approach paying equally meticulous attention to the
reproduction of the entire audible range (and beyond) will al-
ways yield a more consistent and well integrated result.
In short, a more natural, realistic and, above all, truly musical
result.
In our quest for a high frequency driver that would shine in its
specified arena, yet mesh seamlessly with its companion driv-
ers, Gryphon experimented extensively with tweeters repre-
senting a broad spectrum of exotic technologies and rare
materials.
Based on comprehensive study, measurements and listening
sessions, the extreme high-frequency range in the Gryphon
Kodo has been entrusted to the extraordinary Mundorf Air Mo-
tion Transformer that moves air by driving an extremely low-
mass folded sheet in a semi-perpendicular motion via a
powerful magnetic field. Following extensive research into ma-
terials and diaphragm geometry, the Kodo AMT employs a
heat-resistant Kapton film base, aluminium conductor traces
and an innovative fold geometry.
Because of the large surface area of its pleated structure, the
Air Motion Transformer moves a large air volume with minimal
diaphragm motion for lightning fast transients with flat fre-
quency response well beyond the audible range with negligi-
ble distortion and a total absence of compression.
For ideal integration of the high sensitivity (100 dB) tweeter
with the acoustics of the listening space, the AMT tweeter in-
corporates external hot-swappable, hand-tuned Duelund
graphite resistors for three-stage, user-accessible +1.0 dB
tweeter adjustment. Empowering the user to adjust high fre-
quency response for a seamless presentation without deleteri-
ous switches or rheostats, Duelund graphite resistors snap into
place with convenient rear-panel clips, then connect with their
original leads to screw terminals. The Gryphon Kodo high fre-
quency module can deliver ideal high frequencies with mild
roll-off (-1.0 dB), neutral response (0 dB) or mild boost (+1.0
dB) to integrate perfectly with the acoustics of the listening
room.
Active Q Control
The Gryphon Q Controller is an innovative room-adaptive de-
vice that allows user adjustment of the total system resonance
frequency and of system Q for ideal coupling to any room.
