Kenjit, I don’t know if your post is serious, but I’ll give you a serious response. All speakers necessarily are made with compromises, both to cost and to physics. The notion of perfection is entirely subjective, and moreover since I don’t know what your criteria are, I cannot begin to answer your question.
A transducer also interacts with the room dynamics and the associated equipment, the latter in often unpredictable ways. Active EQ such as Room Perfect can get you a long way to a great sound (or so I understand, as I haven’t been able to use it myself).
So, there is no speaker that would sound perfect to everyone in every situation. Hence, how can the universe of speaker designers anticipate your particular requirements?
If you really want to try to get perfect speakers, put together your requirements/critera along with a hefty check to a speaker designer and see if they will make you something custom. Who knows? Maybe for a 100 grand the designer of the LS50 would be happy to take on a side project. You can certainly pay more for imperfect (for you) speakers and besides, can you really put a price on perfection?
