For a wonderfully low and timpani-esque bar tone beneath the range of the bass xylophone, Sweetwater pros recommend the KB/KBX contrabass rosewood resonator bars from Studio 49 as an exceptional solution. Each gorgeous piece of rosewood is tuned perfectly for superior harmonic overtones to deliver an enviably bright and woody attack. Below the bar is Studio 49’s resonator box constructed from 12mm of solid pine and acoustically engineered with multiple interior chambers to provide maximum resonance that matches the pitch of each bar. On the outside, integrated handles make transport, storage, and cleanup an easy task, as well. Durable and built to last for years of musicianship, the contrabass rosewood resonator bars are a great piece of classroom percussion that students and educators all over will appreciate!
