 Basically the tonehole is in the wrong place - it's too high up the instrument and made  too small to compensate for this.
 On a few clarinets e.g. full boehm models and models with single piece bodies like Rossi's the tone hole is correctly proportioned and in the correct place and so produces a C# that properly matches the adjacent notes.
 
 Makers do this to save cost of putting the tonehole through the tenon area where it belongs.
 On some makes/models the makers seem to get a better compromise of pitch and tone than others with there incorrect positioning.
 
 You just have to learn how to voice this note to get best possible result.

 If you're lucky, the note is both fuzzy and flat. If that's the case, a little undercutting can free it up some and raise the pitch. Just keep in mind that the twelfth will mirror the change, which can result in a wild, sharp

 On my clarinet (E12F), low C# is not breathy at all. It sounds as nice as any other lower register notes.
