REDCATT SW8.01X4 4 ohm 8-inch Subwoofer speaker

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 allows the cone to travel in long linear motion. Together with lightweight cone,this combination provides remarkable strength, high efficiency and a excursion linearity of 13mm.

Magnetic Circuit

REDCATT engineers have developed an efficient, 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.
