Adams Concert Series Xylophones come in a wide variety of sizes and bar materials to accommodate every player and venue, whether you’re in the orchestra concert hall or on the field. Concert 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. Carefully selected Honduras Rosewood bars are manufactured in a graduated wide bar format for optimum sound quality and supreme projection. As with all Adams instruments, each Xylophone bar is tuned to the sixth overtone and precisely voiced using our proprietary computer-assisted method. This ensures the sound is perfectly balanced throughout the entire range of the instrument.
