    To improve upon that was a daunting task. Wilson Audio’s engineering team accom- plished its goal and, with Sophia Series 2, has again raised the bar in terms of per- formance, value, and sheer beauty.

The concepts outlined below are equally relevant when dealing with multi-channel audio or home theater. The careful application of these concepts, as you evaluate the acoustical characteristics of your own room configuration, will allow you to optimize the performance of your Sophias.

    All audio equipment will sound best after its components have been broken in for some period of use. Wilson Audio breaks in all woofers and mid-range driv- ers for a 12 hour period. All drivers are then tested, calibrated, and matched for their acoustical properties.

    The use of these materials in Sophia result in an enclosure that is inherently inert and non-resonant. All of these structural aspects are combined, allowing Wilson Audio to deliver a product that maintains the strictest structural tolerances, durability, and reliability. This also means that the Sophias will have consistent, repeatable performance, unaffected by the climatic conditions, anywhere in the world.
