Question: How is the Classic II S.E. different from the original Classic II stethoscope?
Answer: In 1996, a decision was made to replace the standard floating diaphragm on the Classic II with the tunable diaphragm. The result was the S.E., or special edition of the Classic II.

Question: Can I put a tunable diaphragm on my older Classic II, turning it into an S.E., or special edition?
Answer: No, the metal portion of the chestpiece has to have an attenuating ring present. under the diaphragm. The ring is formed during the manufacturing process. Older Classic II chestpieces do not have an attenuating ring, which is an essential part of the tunable technology.

Question: Why would I want to have a tunable diaphragm on a two-sided stethoscope?
Answer: A tunable diaphragm offers convenience and versatility. A tunable diaphragm on a two-sided stethoscope offers one the choice of using it as a traditional stethoscope, or using only the diaphragm side for both low- and high-frequency sounds.
