Corum Audio Sinatra System

A speaker system is usually a compromise and must fit standard industrial production requirements. By that I mean usually the limitations are set by what the industry can easily build with standard machine mills, saws, drills, sprayers. The budget is the main limitation so usually we have square boxes, at most a few small spherical parts to make it more appetising. We worked without a budget , we worked ignoring the limitations imposed by standard production and we strove towards our goal to have the best sounding system even if it was a crazy idea, almost impossible for a company whose God is profit. Why not think about a work of art rather than of a box for the reproduction of sound. It is a system to show off; an astonishing system to leave your guests and friends really impressed. A status symbol.
