Design Notes
The CX6F-140F is a high efficiency, (93dB 1watt / 1 meter) 6.5-inch coaxial speaker with very linear frequency response characteristics and high power handling capability. The mid-woofer utilizes REDCATT developed paper pulp cone that has proven its performance in many our successful designs. The HF section was designed around our most successful dome assembly as used in 140FCD. The mini waveguide is CNC machined from single piece of aluminum, given the whole assembly incredible precision. The combination of used materials with our state of the art quality production yields in well performing driver even in the most demanding extreme conditions.
Magnetic circuit design
REDCATT engineers have developed ferrite-neodymium based magnetic circuit, capable of delivering the highest level of performance in a small form factor. The combination of ferrite and neodymium delivers an excellent magnetic performance. The magnetic circuit design is optimized to generate the minimum amount of flux modulation, providing exceptional stability. Aluminum demodulation ring is assembled in the HF section.

Enclosure Recommendations
LF enclosure alignments:
- Vented (primary) - 50 mm port:
5 L / Fb = 95 Hz / ~94 mm physical port / 8.57 m/s peak port velocity
8 L / Fb = 80 Hz / ~79 mm physical port / 7.22 m/s peak port velocity
12 L / Fb = 70 Hz / ~64 mm physical port / 6.32 m/s peak port velocity
(All velocities within hi-fi 17 m/s and PA 22 m/s limits; subsonic high-pass
filter at Fb - 10 Hz mandatory to prevent over-excursion below tuning frequency)
- Sealed (secondary):
3.49 L / Qtc = 0.707 / f-3dB = 182 Hz (Butterworth)
1.94 L / Qtc = 0.85 / f-3dB = 188 Hz
1.25 L / Qtc = 1.00 / f-3dB = 203 Hz
0.80 L / Qtc = 1.20 / f-3dB = 227 Hz (very compact; sub-assisted applications)
