FERRITE
The 35FR is a high efficiency, (84dB 1watt / 1 meter) 3.5-inch full range speaker with linear frequency response characteristics and high power handling capability while generating low harmonic distortion artifacts. The 35FR uses a lightweight exponential paper pulp pressed cone assembly along with a NBR single roll geometry surround. The combination provides remarkable strength, high efficiency and sustained output under extreme conditions.
Magnetic circuit design
REDCATT engineers have developed ferrite based magnetic circuit, capable of delivering the highest level of performance, providing a consistent, high integrity magnetic flux gap, low distortion characteristic. The magnetic circuit design is optimized to generate the minimum amount of flux modulation, providing exceptional stability. Copper demodulation cup is assembled over the t-pole.
