Magnetic Circuit Design Redcatt engineers have developed a lightweight, neodymium outside ring based magnetic circuit capable of delivering the highest level of performance providing a consistent, high integrity magnetic flux gap, ultra low distortion characteristic and high efficiency cooling system. The magnetic circuit design is optimiszed to generate the minimum amount of flux modulation, providing exceptional stability.

Power Handling At the core of the 8FHW is it’s voice coil technology featuring a composite polymide former material capable of withstanding peak temperatures in excess of 200C, well beyond the thermal requirements of modern audio systems and providing optimal structural strength and thermal characteristics. Former strength provides the ideal transfer of power between the voice coil and the cone assembly and assists in reducing distortion artifacts. By combining this material with state of the art adhesives, the 8FHW delivers outstanding performance.

The 8FHW is 8-inch low bass woofer with linear frequency response characteristics, high power handling capability while generating low harmonic distortion artifacts. The single roll rubber surround design allow the cone tro travel in long linear motion. Together with lighweight cone,this combination provides remarkable strength, high efficiency and a excursion linearity of 13mm.

vanced REDCATT pulp. The woofer cone is also extensively treated to withstand harsh environments and high humidity. Metal parts in the speaker assembly are coated for extreme weatherization protection. The 8FHW is ideal for use in smaller volume, vented port applications where large amounts of very low frequency response is desired. Typpical example could be hi-fi subwoofers, gaming or cinema sub-woofers, . Redcatt Ltd. implements the use of advanced Klippel transducer technology equipment in all critical areas of transducer development including R&D, Material Science, Power and Production Testing. Full Klippel reports are available for all Redcatt transducers upon request.
