REDCATT 25TF-431A - 4 Ohm

REDCATT 25TF-431A - 4 Ohm Tweeter

Key Features

• easy implementation, integrated waveguide
• weather sealed
• ballanced frequency response, low resonant frequency

Design Notes

25TF ferrite based tweter was design for high quality audio applications. It sports aluminum dome, carefully attached to poly-silk surround. Furthermore, the magnetic system and dome sub-assembly is inbuilt into carrier that is later further assembled with our waveguide. The magnetic circuit delivers robust and consistent B field. Its design has been FEM optimized and features small resonant chamber. All metal parts are coated for weather protection. The dome is carefully attached to CCAW winding voice coil, wound on a Kapton former. Our precission adhesive dispensing ensures consistency and reliability of all our products. The best application of this device is in studio monitors, 2-way Hi-Fi systems as well as outdoor products.
