B 45 vs. B45 dot

[Tom C.]

Does anybody know the difference between a Van Doren B45 and a B45 DOT?
Van Doren's brochure says they both have a tip opening of 1.195 mm, and a
facing length of 21.5 mm.
Has to be something else, but what? (It's not the "profile".)
Thanks. Tom D.C.

I believe the dot has a larger chamber.

Just got a pdf version of the Vandoren Magazine No. 2. This is what they
said:

The B45, B45 . and B40 .

"quoted from the Vandoren Magazine No. 2 - Choosing the Right Mouthpiece"

The B45, created in 1968 by Bernard Van Doren, came as a revelation for many
clarinetists. It was rapidly adopted by the leading clarinet players of the
time. This mouthpiece became another standard of professional comparison,
thanks to its innovative features:

- A wider tip opening than the 5RV

- A medium length facing

Result: great evenness, with a smooth and pure tone and easy articulation.

The B45 . and then the B40 were based on the B45, with similar features for
the tip opening and length of the facing;

The B45 . is characterized by a "trapeze" configuration (widening of the
passage from the bore to the chamber). It produces rich harmonics in the
entire sound spectrum.

The B40, with a wide tip rail, was designed in collaboration with Jean-Paul
Gauvin. It can be used with softer reeds while retaining a velvety sound in
all registers. This is why the B40 is becoming increasingly popular among
clarinet players.
