Designed for the player whose needs are not met elsewhere, these mouthpieces affords enhanced projection, even timbre from ppp to fff, and the same great intonation throughout all registers that Marcinkiewicz mouthpieces are famous for.

ProLine Concert Hall mouthpieces have a unique exterior design that offers optimal nodal enhancement by placing integral vibration dampers in specific, calculated areas. The net result is a mouthpiece that gives an extremely stable center of pitch, allows unprecedented dynamic levels without distortion and provides a rich, dark symphonic sound without the additional mass of a conventional heavy wall mouthpiece.
