8" | 8FIND
Ferrite Mid-Woofer
Key features:
- EXTENDED FREQUENCY RESPONSE, high efficiency
- Carbon fiber loaded and reinforced paper cone
- Nomex spider
Design notes:
The 8FIND is a high efficiency, (97 dB 1watt / 1 meter) 8-inch mid bass woofer with incredibly linear frequency response characteristics, high power handling capability while generating low harmonic distortion artifacts.The 8FIND uses a lightweight carbon fiber loaded cone assembly along with a precision double roll surround. This combination provides remarkable strength, high efficiency and a excursion linearity of 9.4mm.Magnetic CircuitREDCATT 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.
