Fixed Suspension Midrange ( FSM )
Instead of a normal suspension construction, the
AAD Fixed Suspension Midrange ( FSM ) uses
an innovative design. The small movements of
the cone lightly compress and stretch the ring.
Because the ring's surface area is small, it
radiates relatively little sound, and what little
movement it does have always follows the cone
edge because it is so tightly coupled.
Firstly, the whole cone begins to respond much
quicker in a given time. In the time domain this
equates to a better transient response. In the
frequency domain it indicates a more extended
high-frequency response, and indeed the
response of this driver is smoother to higher
frequencies and allows a better-integrated
crossover to the tweeter. Secondly, the final
pattern of cone movement is even more random

What emerges is a detailed, incredibly true
and transparent high-frequency presentation.
Power response is immediate, with lightning
speed and instantaneous reproduction of
transient information. Integrity of the upper
harmonics is completely intact and the
tweeter's uncanny accuracy and high-fre
quency articulation is a decided advantage
in an era of extended bandwidth formats.
than for the regular driver, with a resultant
increase in clarity for the listener.
