Design Notes
The CX12F-140F is a high efficiency, (95 dB 1watt / 1 meter) 12-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 ours successful designs. The HF section was designed around our most successful dome assembly as used in 140FCD and has integrated symmetrical aluminum horn. The combination of used materials with our state of the art quality production yields in well performing driver even in the most demanding and extreme weather 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
In sealed enclosures, the LF Qts of 0.50 gives the system designer genuine flexibility: the Butterworth alignment at 63.9 liters (f-3dB approx. 79 Hz) suits larger PA enclosures with extended bass; Qtc = 1.00 at 21.3 liters (f-3dB approx. 88 Hz) is practical for column and surface-mount designs; Qtc = 1.20 at 13.4 liters (f-3dB approx. 99 Hz) suits compact column bays with active subwoofer support. Vented alignments (30-80 L, tuned to 28-45 Hz with a 100 mm port) extend bass below Fs with port velocities within PA limits in all recommended alignments.
