Peavey RADIAL X 22 - Manual (Page 2)

constructed of an integral one-piece titanium
diaphragm/suspension assembly. The one-piece
titanium diaphragm reduces the amount of moving
mass, extending the high frequency response of the
driver.
The Rx22 magnet structure has been reshaped
internally to focus the magnetic energy across every
turn of the voice coil for lower distortion and
improved linearity. The Rx22 incorporates the latest
in ferrofluid technology. Peavey engineering has
teamed up with the experts in the field of ferrofluid
engineering to develop a special ferrofluid just for
the Rx22. This in part is another reason for
improved power handling, improved high frequency
response and a cleaner crisper high end.
Ferrofluid is a thin, synthetic oil-based liquid
holding billions of submicroscopic magnetic
particles in suspension. It surrounds the voice coil
for a controlled heat transfer. It essentially conducts
the heat away from the voice coil, transferring it into
the surrounding metal of the magnet structure. This
in turn reduces the amount of power compression by
lowering the voice coil temperature and improves
the life of the Rx22 compression driver. One key
characteristic of ferrofluid is its ability to dampen
resonance modes within a speaker system. The
special grade of ferrofluid engineered for the Rx22
has been optimized for enhanced sound quality and
performance.
Every Rx22 driver is subjected to a complete
series of computer-control tests designed to ensure
total adherence to specifications.
APPLICATIONS
The Rx22 has been designed and engineered
for use with Peavey horns. However, any horn may
be used as long as it consists of a standard 1 3/8" –
18 standard thread coupling. The Rx22 is an
excellent choice for upgrading an older system with
minimal expense.
DESIGNER NOTES:
The Rx22 driver is designed for use between
the frequencies of 500 Hz to 20 kHz. However, we
have found through years of experience as crossover
designers for commercial applications that optimum
driver performance can be achieved if the engineer
limits the crossover design to 1000 Hz as compared
to the 500 Hz lower limit of the driver. The 1000 Hz
limit will greatly improve reliability plus improve
the power handling by an extra 15% over the
500 Hz limit.
INSTALLATION-DIAPHRAGM
REPLACEMENT:
Female spade lugs (supplied with each Rx22)
should be used for connecting the leads from the
crossover to the terminals on the Rx22. This will
permit rapid field diaphragm replacement in the
unlikely event of failure. The Rx22 diaphragm
replacement kits are available from Peavey dealers
and include complete gap cleaning instructions. (To
prevent gap contamination by foreign materials, a
failed diaphragm assembly should not be removed
before a new diaphragm assembly is ready to be
installed.)
LIMITED WARRANTY:
Peavey Model Rx22 compression drivers are
warranted to the original purchaser to be free from
defects from materials and workmanship 1 year after
purchase date. Warranty status shall be determined
by the authorized Peavey dealer or by Peavey upon
inspection of inoperative unit at the factory. See
warranty sheet for details.
