8" | 8FIND
Ferrite Mid-Woofer
Key features:
- EXTENDED FREQUENCY RESPONSE, HIGH EFFICIENCY
- CARBON FIBER LOADED AND REINFORCED PAPER CONE
- NOMEX SPIDER
Design notes:
The 8FHW is 8-inch low frequency 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, yet strong cone,this combination provides remarkable strength, high efficiency and a excursion linearity of 13mm (one direction).Magnetic CircuitREDCATT engineers have developed an efficient, ferrite based magnetic circuit, capable of delivering the high 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
