High-frequency super tweeters
A high-frequency super tweeter is an additional loudspeaker designed to reproduce ultra-high frequencies beyond 20 kHz, up to 90 kHz depending on the model. Installed as a complement to existing speakers, it extends the audio system’s frequency response to reveal harmonics and details absent from traditional tweeters. These components integrate into hi-fi and home theater setups to enhance overall sound perception. Learn more
Operation and principle
Super tweeters specialize in reproducing extreme frequencies that the built-in tweeters of speakers can only reproduce with reduced directivity or noticeable distortion. They generally operate from 6 kHz or 8 kHz depending on the model, enabling better reproduction of transient leading edges. This bandwidth extension alters the perception of the entire sound spectrum, including mids and bass, by restoring the full harmonic structure of recordings.
Transducer technologies
Several technologies are used in high-frequency super tweeters. Planar ribbon models employ an aluminum membrane a few microns thick driven by neodymium magnets for a fast transient response. Compression tweeters with horns offer high efficiency and treble precision. Some manufacturers also offer electrostatic transducers or AMT (Air Motion Transformer) configurations for specific dispersion.
Installation and compatibility
These auxiliary speakers connect directly to the amplifier outputs or in parallel with existing speakers via the supplied link cables. An adjustable attenuator lets you match the level to speakers with sensitivities between 80 and 110 dB. Super tweeters work with all types of speakers: floorstanders, bookshelf speakers, wideband speakers, center channels, and surrounds. The integrated passive crossover ensures seamless integration without modifying the system.
Applications and audio formats
Super tweeters reveal their potential with high-resolution audio formats that contain information beyond 20 kHz. Vinyl, SACD, FLAC, DVD-Audio, and UHD Blu-ray discs particularly benefit from this frequency extension. In home theater as well as stereo listening, they provide improved spatialization and enhanced definition of the three-dimensional soundstage.
Impact on listening
Extending the bandwidth into very high frequencies influences the physiological and psychological perception of the entire audio spectrum. Even listeners whose hearing no longer extends beyond 10 kHz notice improved perception of bass and mids thanks to the complete restitution of harmonics. This change results in heightened realism, a natural sense of space, and better timbral definition without adding artificial processing.
