BlieSMa T34S-4

High‑sensitivity tweeter with a 34‑mm silk dome.

The Bliesma T34S‑4 employs a 34‑mm dome made from natural silk, chosen for its smooth tonal character and controlled behaviour at high frequencies. The diaphragm’s low moving mass of 0.27 g contributes to excellent transient accuracy and high efficiency.

The neodymium motor operates in full magnetic saturation and includes a copper sleeve that reduces nonlinear and modulation distortion. The two‑layer CCAW voice coil is wound on a titanium former with reduced height, ensuring stable performance and minimal thermal compression during demanding operation.

A rear‑mounted magnet system and a flush‑integrated surround help maintain a uniform frequency response and consistent dispersion across a wide listening angle. The aluminium front flange and rear chamber are powder‑coated, while the chamber itself is filled with natural wool damping to suppress internal reflections.

The tweeter is equipped with a non‑removable metal grille that protects the silk dome without affecting acoustic performance.
