The REDCATT 140FCD design has been optimized to provide high SPL output with very low distortion artifacts. At the core is its polyamide composite dome, formed as single piece with the surround. Surround has FEM optimized resonance control features. The voice coil former is carefully bonded to the dome with the very best available adhesives. The strong and reliable joint between the voice coil former and the dome ensures the energy is well transferred from the moving voice coil onto the dome and it also guaranties the longevity of the compression driver.

Professional Loudspeaker-
140FCD High Frequency Compression Driver
• 1.45 inch (35.5 mm) Polyamide dome compression driver
• 1.0-inch Exit Throat
• Polyamide diaphragm
• Advanced ferrite based magnetic motor structure using
super low carbon steel
• 1,200 - 18,000 Hz frequency response
• 1.4 inch (36 mm) voice coil diameter
• 107.5 dB 1 watt / 1 meter sensitivity
• 30 watt AES / 60 watt program power handling
• Ideal for high output two-way and multiple way system,
multi driver- compact high quality line array systems
The 140FCD compression driver is a high performance high
frequency device ideal for professional loudspeaker systems. The
driver’s ferrite based magnetic circuit provides a robust, high
force BL field providing precision control of the polyamide dia-
phragm assembly. The unit delivers extended frequency response
and high power handling thru 1.0inch exit throat.
Diaphragm Assembly
The driver features a 37mm polyamide diaphragm formed as
single piece with polyamide suspension that consists resonance
controll features.
The dome assembly is carefully attached to a high temperature
voice coil former that withstands the long term power charac-
teristics typically seen in professional applications. The acoustic
output exits through a radial slot phase plug and a 1.0 inch throat
aperture. Nominal sensitivity is 107.5 dB 1watt / 1 meter.
Magnetic Circuit Design
Redcatt has focused on designing an optimized ferrite based
magnetic circuit capable of delivering the highest level of per-
formance and value. The ferrite circuit is optimized to generate
the minimum amount of flux modulation providing exceptional
stability. This effort has resulted in a device that offers uncom-
promising performance featuring high efficiency, exceptional
transient response and controlled distortion characteristics.
Mechanical Design
Connection of speaker cables is through fast-on connectors. Horn
mounting is via four M4 threaded mounting holes.
The diaphragm assembly has been designed with easy field service
in mind as it can be removed and replaced within minutes.
Redcatt Ltd. Implements the use of advanced Klippel transducer
technology equipment in all critical areas of transducer develop-
ment including R&D, Material Science, Power and Production
Testing. Full Klippel reports are available for all Redcatt transduc-
ers upon request.
