Absolute high-frequency brilliance
The HELIX PR T25-S premium tweeter is an example of absolute excellence within the PURE speaker lineup. It distinguishes itself with the lowest possible manufacturing tolerances and exclusive use of top-tier materials, such as the coated silk dome. This component leads to the faithful rendition of even the finest details, ensuring a smooth and natural sound reproduction for an unmatched high-frequency experience. The highly efficient neodymium magnet maintains a consistently optimal, high magnetic flux linearity. Furthermore, its smart and compact design offers diverse mounting options for a universal installation. The anodized aluminum flush mount housing with the solid mounting ring allows a concealed installation, while the included grilles, available in two exclusive designs, provide both protection and aesthetic options. High-grade aluminum flush-mount housings (PR ATP25) are also optionally available to refine your sound setup.
