The Adams Alpha Series family of instruments represents the state of the art in modern instrument design. The high sweeping arc of the resonators, rich wood stain finish, and polished aluminum name plate all merge seamlessly to form a visual and aural statement in modern design. Alpha Series instruments now feature the Adams Apex Frame — with its unique minimalist side pillar design, integrated shore braces, and ultra-strong two-piece crossbar, Apex instruments are quick to assemble and easy to transport, allowing performers at any level to achieve their peak performance. In collaboration with Kessels Granger Design Works, Adams has created the newly contoured rails, end pieces, and resonators, available in a variety of color and stain combinations. Adams Alpha Series Marimbas use only the finest aged Honduras Rosewood available. Using a proprietary computer-assisted method, all Adams bars are meticulously precision tuned through an incredible sixth overtone in the lower register. This exclusive tuning process gives Adams keyboards the most stable pitch and evenness of sound available, while making the upper registers sound more open and resonant.

Adams Endurance Series Marimbas are designed for maximum strength and durability, allowing for easy transport across any field or concert stage. Featuring solid steel accessory rails, large rubber field wheels, and precision height adjustability, Endurance Marimbas provide the bottom end for any ensemble while standing up to years of hard playing, weather, and loading. Available in 4.3, 4.6, and 5.0 octave configurations. Only the finest aged Honduras Rosewood is considered for the keyboard which is then tuned via the Alpha Tuning Method producing not only the perfect fundamental note but the perfect harmonic structure throughout the upper register. The resonators found on all Endurance Series Marimbas are structurally welded for the utmost in strength and isolation from mechanical noises. Each structurally welded resonator tube is carefully designed to amplify the fundamental note and give you maximum volume, sustain and clarity. Lower register resonators are tunable and each resonator system is mounted on a rubber isolation system to ensure the maximum resonance and eliminate all possible mechanical noise.
