RedCatt 8FR - 4 Ohm

Key features:

• lighweight, yet strong paper cone reinforced by bamboo fibers
• working range up to 15kHz
• aesthetics tuned for moder hi-fi look

Design notes:

8FR was developed for Hi-Fi applications where single point audio source is required. Our engineers designed the cone to be lightweight, yet strong, using our new paper pulp reinforced by bamboo fibers. The driver sports wizard cone that extends the working range up to 15kHz, paired with bullet style phase plug. Combination of these two key features ensures smooth frequency response and an optimal sound reproduction on and off axes. Magnetic circuit was design to deliver robust B field across the whole range of working frequencies. Additional copper shorting cup further improves the driver behavior in mid-high working region. The aesthetics of this driver were tuned to support modern hi-fi system designs, where the driver can be exposed to the end user. Distinctive colors ensures the driver can be featured as part of the overall industrial design.
