Peavey 22 Applications, Designer Notes, INSTALLATION-DIAPHRAGM Replacement, Limited Warranty

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.

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.
