25TF ferrite based tweter was design for high quality audio applications. It sports single piece poly-silk dome, formed together with 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. This version of 25TF style tweeter shares all components with aluminum dome version 25TF. The difference is only the dome itself. While aluminum dome delivers crisp HF, the poly-silk dome is dampened in the high frequencies and has a smoother roll off. Each version has its own application, that perhaps depends on personal preferences of the audio engineer. The best application of this device is in studio monitors, 2-way Hi-Fi systems as well as outdoor products.
