  • Page 13: Section 2.0 Care Of The Finish

    While the paint seems quite dry to the touch, final curing and complete hardening takes place over a period of several weeks. To protect the finish of Sophia during final manufacturing, shipment, and setup in your listening room, we have applied a remov- able layer of protective film over the painted surface.

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

The high hardness of these composites not only offers excellent acoustical proper- ties but also provides an ideal surface for painting, ensuring that the high gloss fin-...

    O U R O O M Note: The following section contains general information on room acoustics and loudspeak- er/room interaction. The concepts outlined below are equally relevant when dealing with multichannel audio or home theater. The careful application of these concepts, as you evalu- ate the acoustical characteristics of your own room configuration, will allow you to optimize the performance of your Sophias.

    ʼ O P H I A W N E R A N U A L Slap echo is a common acoustical problem in the typical domestic listening room, because most of these rooms have walls of a hard, reflective nature, usually being only occasionally interrupted by curtains or furniture.

Tube traps manufactured by the ASC corporation have been found to be effective in reducing some of these low frequency room colorations. While custom designed and constructed bass traps, such as perforated Helmholtz resonators, provide the greatest degree of low frequency control.

  • Page 27: Section 4.0 Final Listening Room Setup (Voicing )

    We will also offer some detailed suggestions on the setup of Sophia, but we strongly suggest that you have your local Wilson Au- dio dealer perform the final speaker “voicing” for you. They are specially trained in setting up Wilson loudspeakers and will ensure that you realize the full value of your purchase.

  • Page 28: Zone Of Neutrality

    This location is where the speakers interact the least with ad- jacent room boundaries. It is important to move your Sophiaʼs away from the place- ment area during this process. We also recommend that you wait to spike your speakers until the final system setup is completed.

If you extend the inner and outer boundaries of the Zone for the side walls and the front wall (behind the speakers), they will intersect.

    Set the crate so that the bottom of Sophia is towards the floor. While one person holds the crate, the other person should gently slide the Sophia out of the crate. Be careful not to scratch the sides of the painted en- closure.

    Very high quality binding post connections are provided to facilitate connect- ing Sophia to your amplifier. Locate the 1/2” Hex Head tool from your took kit to tighten spade connectors of your speaker cable to attach the main output from the amplifier to the Input terminals located on the bottom module in the rear.
