AT-28A (B-stock) by DD Audio
The AT-28A (B-stock) from DD Audio is a Dome Tweeter with a lightweight and rigid ceramic dome. The technical features include a powerful neodymium motor and a tuned rear cavity to support off-axis reproduction. The movement of the 28 mm diaphragm is linearized by a treated silk surround. The system has an impedance of 4 Ohms and achieves a peak power of up to 125 Watts. The RMS power handling is specified at 50 Watts. The laser-engraved back panel marks the enclosure design of this tweeter. It is B-stock with technical integrity from show car installations, although there may be cosmetic defects or damaged original packaging.
