Product details REDCATT 31NFR
REDCATT 31NFR 3.0" Full-Range Woofer 8 Ohm
Â
The REDCATT 31NFR is designed as a high-efficiency full-range woofer for compact systems that need broad bandwidth from a small driver. Its lightweight hard anodized aluminum cone and NBR single-roll surround help deliver extended high-frequency response, stable output and low harmonic distortion across its working range.
Â
A neodymium magnetic circuit keeps the motor compact while maintaining a strong, stable flux gap. REDCATT’s motor design is optimized to reduce flux modulation, and a copper demodulation cup over the T-pole further supports low-distortion performance. This makes the 31NFR a practical choice for space-conscious woofer applications where clarity and consistency matter.
Â
With 30 W AES power handling, 60 W continuous power and 120 W peak capability, the 31NFR offers useful output for its size. Key parameters include a 115 Hz resonant frequency, 84.49 dB sensitivity, 6.30 ohm DC resistance, 0.880 Qts and 0.85 liter Vas, giving designers a clear basis for compact loudspeaker development.
Â
The 31NFR fits hi-fi columns, outdoor and portable products, multi-way systems and other compact speakers. Installation dimensions include a 71.5 mm baffle cutout, 45.3 mm mounting depth from flange to rear and four mounting holes, while the recommended sealed alignment is a very compact 0.05 liter enclosure with Qtc options of 0.85, 0.707 or 0.6.
