audio/video reproduction requires a well-matched system consisting
of a high performance audio/video source, amplifier, speakers,
cables and a rack to house everything. All components of this
system contribute to a high performance audio/video experience.
But like a chain, the system is only as good as its weakest
link. No matter the quality of the CD player or the speakers,
if the rack is not dissipating vibration, one will not experience
the full capability of its system.
A properly designed high-performance anti-vibration rack or
shelf virtually eliminates vibration, a significant detriment
to music reproduction. Composite Products utilizes carbon
fiber, a leading edge aerospace material, to accomplish the
goal of virtually eliminating vibration, thereby assuring
the best audio/video reproduction the system is capable of
The design was created by engineers with many years of experience
and numerous patents to their credit. Starting from a concept,
a 3-dimensional computer model of the product was made. Then
the rack's design, material properties and working condition
were simulated by Finite Element Analysis (FEA), a highly
advanced computer simulation and analysis technique. The computer
model was then optimized to deliver the best performance.
Prototypes were made according to the optimized design and
extensive testing was performed by outside laboratories to
verify the goals of the design. As an example, the vibration
test graphs clearly show
that when a vibration of 0.2 g's is introduced to the rack,
the rack immediately absorbs the vibration and drops it down
to the 0.09 g level up to the 150 Hz range, then the vibration
falls very sharply to the 0.002 g level.
isolation rack is designed and constructed with the primary
goal of eliminating vibration in the audio/video components.
We use carbon fiber, the best vibration dissipateing material
in the middle and high frequency ranges and Sorbothane, a
soft visco-elastic material, to absorb and dissipate vibration
at low frequencies. Carbon fiber's high stiffness properties
along with its superior damping properties result in the best
structure for eliminating vibration. The CF-1000 employs a
structure similar to satellites, resulting in a state of art
anti-vibration audio/video rack.
The posts are the primary structural damping components in
the CF-1000. The posts support the shelves and therefore the
equipment sitting on the shelves. The posts also isolate each
shelf from the other shelves, the floor and the outside world.
The CF-1000 carbon fiber posts are optimized to protect against
deformation caused by vibration while dissipating vibration
very effectively. The posts are made from several hundred
layers of carbon fiber epoxy composite. Vibration simply gets
dissipated when it travels through so many layers of carbon
We offer two options for our shelves, a carbon fiber covered
acrylic shelf and a clear acrylic shelf, both offering excellent
stiffness, damping and anti-vibration properties.
Sorbothane rings are employed to damp low frequency vibration.
Fiberglass studs are used to fasten the structure together.
Fiberglass also offers very good stiffness, strength and damping.
We do not use any metal or glass in our CF-1000 racks. Although
these materials have good stiffness, they have virtually no
damping properties and are well known for their "ringing"
