The Bliesma T34A‑4 features a 34‑mm aluminium‑magnesium alloy dome with variable thickness, designed to achieve a first breakup mode at 27 kHz. The lightweight diaphragm provides high sensitivity, fast transient response, and accurate reproduction across the upper midrange and high‑frequency spectrum.

The fully saturated neodymium motor incorporates a copper sleeve to reduce nonlinear and modulation distortion. The underhung CCAW voice coil, wound on a titanium former, minimizes thermal compression and maintains stable performance under dynamic load. A 3‑mm linear excursion and a large vent channel allow clean operation at lower crossover points.

The tweeter uses a rear‑mounted magnet system and a flush‑mounted surround, resulting in a smooth frequency response and wide off‑axis dispersion. The aluminium front flange is powder‑coated, and the rear chamber is filled with natural wool damping to suppress internal reflections.
