Product details REDCATT 25NFR
REDCATT 25NFR 2.5″ Full-range woofer 8 ohms
The REDCATT 25NFR is a very small full-range woofer built around a neodymium ring magnet motor structure. This motor delivers a high level of magnetic force while keeping modulation distortion low, making the driver suitable for compact systems where clean wideband output is required.
Its lightweight paper cone, NBR rubber surround and Nomex spider are optimized for full-range performance. With a resonant frequency of 123 Hz, Qts of 0.710 and 82.69 dB sensitivity, the 25NFR is designed to deliver balanced output from a small form factor.
The driver is especially suitable for column speaker arrays, multi-way Hi-Fi products and portable speakers. Thanks to its excellent high-frequency response, an additional HF unit is not required in many full-range applications, helping to simplify compact loudspeaker designs.
Installation is straightforward with a 56 mm baffle cutout, 37 mm mounting depth from flange to rear and four mounting holes. Recommended sealed enclosure options include 1.1 liters for a compact, punchy character, or 0.05 liters for a maximally flat Butterworth alignment.
