ET 26.5


ET 26.5 is a dome car audio tweeters designed to achieve perfect frequency response linearity and high sound levels.
This tweeter employs a 26 mm innovative Tetolon dome with hemispheric profile and wide roll surround. A new compression chamber, designed with advanced finite element technologies, increases overall sound-level and improves off-axis dispersion ensuring powerful, neat, undistorted sound. The high energy neodymium magnet and the low carbon content plates contribute to noticeably increase the magnet group stability and permeability. Functionality and efficiency of materials and geometry, to reproduce a transparent, natural sound, even under extended periods of operation.
