REDCATT 81FIND - 8 Ohm

REDCATT 81FIND - 8 Ohm Mid-woofer

Key Features

• EXTENDED FREQUENCY RESPONSE
• Ideal for small and portable 2-way systems
• Affordable, yet very capable design for cost sensitive product

Design Notes

The 81FIND is a high efficiency, (96 dB 1watt / 1 meter) 8-inch woofer with linear frequency response characteristics, good power handling capability while generating low harmonic distortion artifacts. The 81FIND uses a lightweight glass-fiber loaded cone assembly along with a high excursion M-roll surround. This combination provides a lightweight, yet strong, piston. Magnetic Circuit Ferrite based magnetic circuit, capable of delivering the good level of performance, providing a consistent, high integrity magnetic flux gap, low distortion characteristic and high-efficiency cooling system. The metal parts are extensively coated to provide the maximum weather protection. This driver has been chosen by many audio engineers for smaller sized, or portable audio products. It has proven its capability over and over again all around the world, many times in challenging applications or environments. 81FIND is proven design that delivers good balance between performance and cost.
