Adams Onyx Marimba

The Onyx was developed for musicians who seek the depth and projection of a top-tier concert marimba in a more focused, streamlined design. Built on our signature Apex frame, it shares the stability and precision that define every Adams instrument, while its fixed configuration and smart production approach keep it accessible for more performers.

Every element, from the carefully selected Honduras Rosewood bars to the linear resonator design, serves one purpose: to let the sound speak for itself, while offering an instrument that stands out for its exceptional balance of quality and value. The result is a marimba that feels unmistakably Adams in touch and tone, combining professional performance with practical design integrity.
