The shape of pureness Serenity - Straight High-End

Serenity is an Aural Sculpture with an outer shape that follows basically what we found to be also the optimal inner enclosure dimensions for the woofers, i.e., to relieve them from any specific response of the sealed air volume.

Serenity is the right choice for you who is in search for the most authentic sound experience, infatuated with the original atmosphere and the setting details of the particular recording, and without a “speaker-typical” dye on any of them.

Serenity is available in various configurations such as choice of associated stand and driver control unit. A special feature is the individual customization of her tactile appearance and/ or the arrangement of figural applications to her outer skin.

More design than just design 3BE's one-piece-enclosure

Serenity’s exceptional appearance surely wows everybody even before the first note is played. But beyond, our enclosure is firstly designed for the most amazing sound experience:

Manufactured as one seamless piece without additional bracing installations or other joint wall elements for the most integral resonance management

Inner volume with most distributed 1D/2D dimensions for the most unspecific frequency response

Enclosure material with inner attenuation 3 times higher compared to wood

Homogenous material structure with totally undirected inner energy disspation compared to formed wall materials

Divide and conquer Serenity's driver unit

Serenity is equipped with two 5″-woofers in a D’Appolito arrangement with a 3/4″ dome tweeter. The woofers with aramide cones and 1.4T-magnets from Davis Acoustics are well-proven in many high-end speaker installations over decades up to date. The Illuminator dome tweeter from ScanSpeak presents ribbon tweeter performance from 1k up to 30kHz in a truly minimalistic outer appearance.

The control unit to feed the Serenity drivers is installed outside of the Serenity enclosure. This allows for a maximum of flexibility for the visual and acoustic design of both parts. Control units are available as passive crossover units – the classical way of connecting the Serenity to an existing power amplifier – as well as “active” units with integrated, true bi-amping modules. The filter design comes close to the requirements stated in the theories of Joseph D’Appolito, thus preserving the acoustic benefits of driver arrangement and enclosure design in the best way. All control units are connected to the served Serenity by the same proprietary type of cable with easy-click-connectors.

Inimitable interior objects Customizing Serenity

Serenity’s visual design targets on forgetting about her function. Her appearance can be individualized in countless details to match the particular interior design and taste. The highlight, of course, is the variation of the outer skin, with any abstract patterns, figural applications and/ or personal engravings.

More customization comes with the choice of the appropriate stand, control unit and coloring. Accessories such as the woofer blinds complete the fitting process.
