When a loudspeaker designer produces a world-class product, it is usually the result of years, perhaps decades, of experience gained from designing less ambitious products. To review a particular designer's product history is to witness the learning curve in action as both his skill and technology advance. Successfully battling the laws of physics to produce a truly exceptional loudspeaker is thus thought of as the domain of the seasoned veteran whose vast knowledge and experience culminate in the pinnacle of his career—a world-class loudspeaker. Moreover, it is just these designers, working their way up to their masterpiece, who are the most successful at getting an ambitious design right. The high-end loudspeaker business is littered with the remains of companies that attempted to build a first product far too lofty for their skills.
