Innovative schallwandlertechnologie
RCF boasts over 75 years of experience in designing and manufacturing transducers, with a particular focus on moving coil loudspeakers. Our transducers are engineered to optimize the balance between power delivery and sound purity, achieving minimal distortion and the capacity to endure high power levels for extended periods.
Belastbarkeit
Bei der Entwicklung seiner neuen Schallwandlertypen hat RCF viel Ressourcen und Zeit in die Materialforschung, Erprobung unterschiedlicher Topologien und Leistungsprüfung investiert, um höchste Konstruktionsfestigkeit, optimale thermische Eigenschaften und maximale Belastbarkeit zu gewährleisten. Die RCF Ingenieure haben einen Schwingspulenträger aus einem Polyimid-Verbundstoff entwickelt, der Temperaturspitzen von über 380°C standhält und damit die thermischen Anforderungen an moderne professionelle Audiosysteme weit übertrifft. Dank der Kombination dieses Materials mit speziellen Klebstoffen, unseren innen-/außengewickelten Schwingspulen, der Silikonspinne, gerichteter Hyperventilation und Membranen mit spezieller Faserverstärkung verfügt die neue Produktfamilie von RCF über die widerstandsfähigsten und zuverlässigsten Schallwandler der gesamten Branche.

High-Class Neodymium: Best-in-Class Magnets
Neodymium, a rare earth material, enhances efficiency, power handling, and weight reduction. Our designs, with a 20% stronger magnetic field than typical neodymium grades, enable precise voice coil control and higher force levels (BL). Magnet geometry and configuration are optimized for maximum flux density, incorporating thermal management to ensure reliability. Techniques such as computer-aided magnet optimization and FEM analysis refine magnet weight, flux density, and field saturation, significantly reducing driver weight and harmonic distortion.

The T-pole design minimizes flux modulation in the magnetic assembly during typical voice coil movements within the gap. A specially designed copper ring, pressed onto the pole piece, modifies and reduces the magnetic circuit and voice coil inductance, enabling a controlled extension of the acoustic frequency response.

Gerichtete hyperventilation
Our cooling designs combine various components to create an ideal ventilation system. The RCF engineering team emphasizes finned cooling channels and optimizes the surface area of the front magnetic plate for efficient heat dissipation. The double silicone sealed spider design functions as an air pump, expelling hot air and drawing in fresh air with each movement of the cone assembly.
