Sonor's Primary Series was developed after extensive research to improve the resonance and ensure a balanced sound. Sonor has significantly reworked the xylophone and metallophone resonator boxes. With skillful alterations of the chambers, Sonor has achieved an even more balanced and rich sound for these models. Try them and you'll see and hear the difference.
FSC pure certified Pao Rosa rosewood bars for xylophones and special light alloy bars for metallophones. FSC pure resonator boxes made without screws by using cross laminated birch plywood with 100% glued seams to hold the box together providing a more integral sound chamber. Precision tuning by hand, in the lower range overtone tuning, in the higher range fundamental tuning is applied to all models. Sonor Primary AMP1-1 alto metallophone includes 16 bars, c1 - a2 (with F# and Bb bars), and 1 pair of SCH25 mallets.
