Metadir

Getting loudspeaker directivity right is challenging, largely due to lateral radiation and edge diffraction from cabinet edges.

Metadir is an acoustic metasurface composed of meticulously engineered, compact resonators that offers a novel solution. Its structure suppresses sound waves propagating parallel to the cabinet’s front baffle, thereby eliminating lateral radiation and reducing edge diffraction. The result is more consistent directivity and improved radiation efficiency.

This patent-pending technology offers several unique advantages:

• Broadband directivity control. Suppresses edge diffraction from 2 kHz up to 20 kHz.
• Higher radiation efficiency. Delivers up to x2 more acoustic power for the same input voltage. More definition and clarity. Less driver distortion and wearing.
• Seamless integration. Flat and compact (2cm). Fits into any cabinet shape and size. Works with dome (circular) and ribbon tweeters.
• Uncouples cabinet aesthetics from acoustic performance. Keep enclosures simple or pursue bold industrial design, Metadir ensures pristine sound quality regardless.
