That's because the modern clarinet was constructed so, that for every note you need a different air and embouchure. Very important is the place and length of the register tube, for we can see a pattern where most companies place it random (might vary from 15-20 mm down the body rim, kinda Russian roulette). There is no way that chalumeau notes are equal in tone or frequency to clarion and altisimo if you have a random placed register valve. Of course, this alone can't go without tone holes size, for this shifts both intonation and frequencies - 2 basic things that define how the ear perceives a tone. A major problem of the modern Boehm clarinet is that low joint tone holes are a little bigger than necessary, which makes chalumeau sharp, clarion - flat, and altisimo even flatter. That's because they only thought about intonation, but forgot the air & frequency factor, which is first thing to decide a tone's perception. I think this all comes from an asumption, that the Boehm system was originally a full Boehm (about 3,5-4cm longer). They might have simply "cut" it above the Eb hole, but changed no other specs, hence the troubles we all face today, and have to change barrels, mouthpieces, reeds, etc. If you want to play your clarinet with the same air and embouchure, it needs to be hand-tuned (body, barrel, bell, tone holes), because it is often a matter of 0.1mm. But you should go to someone who knows what to do. And last, but not least - keys pad height. It decides very much air flow, resistance and dynamics. Best regards and indulge!
