Vandoren designed the Series 13 to the 440 scale, especially for American clarinetists. Originally, four models were developed with tables very specific to this series: the mouthpieces M13, M13 Lyre, M15 and M30. Series 13 also extends to other spouts (traditional tables): 5RV, 5RV Lyre, B45, B40, B40 Lyre and M30 Lyre.
A more open mouthpiece than the 5RV Lyre with a longer table guaranteeing flexibility and roundness. Exceptional hold of the "sound paste".
