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.
Select Honduras Rosewood
Every Adams Onyx marimba features a Select Honduras Rosewood keyboard crafted from the same carefully sourced wood batches used for our flagship Alpha series. Our master tuners hand-select each bar with utmost precision, ensuring only the most resonant and visually refined pieces are chosen. After tuning, the very finest bars are reserved for the Alpha, while the remaining select bars form the heart of every Onyx marimba.
The Apex Frame
The Adams Apex mallet frame is designed to provide the best possible sound, to deliver a frictionless experience, and to surprise with astonishing and modern looks, the Adams Apex frame reaches a new peak in design. Apex replaces the Voyager and Traveller frames.
Structural rigidity is the most important part of the Apex design. The position of the high-strengthcentral crossbar creates a very low center of gravity for peerless ease of motion and the ultimate instability. Combined with reinforced crossbar connections, the strength and support of the Apex side pillars provide less frame-noise than any other frame available.
The time tested Adams height adjustment mechanism is the most intuitive, simple, and strongestsystem in the market, and has been transformed in an improved design for the Apex frame. With its unique side pillars and improved crossbar connections, the Apex frame is quick to assemble and easy to transport.
