Patent Review: The Zoltan Bay Loudspeaker Patent

In this article, James Croft reviews a loudspeaker patent granted in 2015 to Zoltan Bay (Tiszaalpar, Hungary). The invention, which is the foundation for the BRS tweeter used in a remarkable series of Bayz Audio loudspeakers, basically describes a horizontally, omnidirectional transducer, using a multiple set of four to eight rolling, half-cylinder film diaphragms arranged in a circle to form a generally omni-directional radiator. This article was originally published in Voice Coil, September 2015.

Bayz Audio from Budapest, Hungary, will be premiering Curante, an omnidirectional, full range loudspeaker, at the 2018 High End show in Munich. The Curante represents a complete re-thinking of traditional speakers by utilizing the patented Bay Radial Speaker (BRS), a unique “radial tweeter” design by Zoltán Bay, CEO and Chief Engineer, in collaboration with Frank Nielsen of Danesian Audio, and András Voloscsuk of Composite Project Kft.
