REDCATT 25TF-X4B 1.0" Silk Dome Tweeter 4 Ohm
Â
The REDCATT 25TF-X4B is a compact dome tweeter designed for high-quality audio applications. Its single-piece poly-silk dome is formed together with the surround, giving the driver a controlled high-frequency character with a smoother roll-off than the aluminum-dome version in the same 25TF family.
Â
The ferrite magnetic system is built for a robust and consistent B field, while the FEM-optimized design includes a small resonant chamber. With a 1000 Hz Fs, 89.5 dB sensitivity, and smooth response, this tweeter is well suited for straightforward crossover development.
Â
Power handling is specified at 10 W AES, 20 W continuous, and 40 W peak. The CCAW voice coil construction and precision adhesive dispensing support consistent production quality, making the 25TF-X4B a reliable choice among high-frequency audio components.
Â
Recommended applications include studio monitors, 2-way Hi-Fi systems, compact PA designs, column arrays, and outdoor products. The 103.5 mm overall diameter, 93.5 mm bolt circle, four mounting holes, 34.2 mm mounting depth, and 0.52 kg net weight make it practical for integration into custom bookshelf speakers and other compact loudspeaker projects.
