RAAL 140-15D Flatfoil Ribbon Tweeter

The RAAL 140-15D Flatfoil True Ribbon Tweeter with Amorphous Core represents a pinnacle of high-frequency transducer engineering, delivering an extraordinarily open and detailed soundstage. This tweeter is ideally suited for discerning audiophiles and professional loudspeaker designers seeking to build or upgrade reference-quality systems, where every nuance of the recording must be preserved with absolute fidelity. Its exceptional clarity makes it a perfect choice for high-end two-way designs or as the top-end complement in multi-way loudspeakers, particularly in systems where transient speed and airiness are paramount.

Technically, the 140-15D employs a true ribbon design with an aluminium flatfoil diaphragm, ensuring minimal moving mass for lightning-fast transient response. The inclusion of an amorphous core dramatically reduces distortion and hysteresis, allowing for a remarkably pure and extended high-frequency reproduction. With a sensitivity of 95 dB SPL at 2.83V/1m and a nominal impedance of 8 ohms, this tweeter is both efficient and amplifier-friendly. It features a recommended crossover frequency of 16 kHz and a cut-out size of 153 mm by 63 mm, with a depth of 93.5 mm, facilitating integration into carefully engineered enclosures. The result is a tweeter that offers breathtaking realism and a truly immersive listening experience.
