  • Page 18 Alignment Cones There are three embedded magnets each on the bottom, left, and right sides of the Duette. Two are located near the front and one near the back of the Du- ette on each of these three sides.
  • Page 19 Align each disc so that it is parallel with the bottom surface of the Duette. Turn the Duette over and carefully align the bottom of the Duette with the top plate of the stand. The brass discs should be directly above the recesses in the stand top plate.
  • Page 20 Duette and the Novel cross- over. Leveling the Duette Stand • Place a level on the left to right oriented axis in the top of the Duette stand. • If the bubble shows that the speaker is leaning toward the center of the room, you will have to lengthen one of the inside spikes down toward the floor.
  • Page 21 (behind the loudspeakers), you will have to lengthen the rear stand spikes down toward the floor. After you have leveled the Duette stands, use the 9/16 inch combination wrench to tighten the stand spike nuts up against the stand, taking care to not rotate the spike.

  • Page 46 Some materials can introduce gross nonlinearities and greatly compromise the performance of the Duette. Avoid lattice work or other obstructions placed in front of the Duette. Hard sur- faces in front of the Duette can cause diffraction and reflective artifacts, which will change the tonal balance as well as the spacial characteristics of the sound.

  • Page 53 The use of these materials in Duette result in an enclosure that is inherently inert and non-resonant. All of these structural aspects are combined, al- lowing Wilson Audio to deliver a product that maintains the strictest structural toler- ances, durability, and reliability. This also means that the Duettes will have consistent, repeatable performance, unaffected by the climatic conditions, anywhere in the world.

  • Page 57 Final Listening Room Setup (Voicing) In its size and price range, the Duette is unmatched in its ability to reproduce the musical event. It is truly state of the art. However, room acoustics and boundary in- teractions affect the sound of a loudspeaker to such a large degree that poor setup can seriously degrade your enjoyment of even the finest loudspeaker.

As above, listen for the point in the room where your voice transitions from bass- heavy and diffuse to neutral. Mark this point with tape.

Slap echo is a common acoustical problem in the typical domestic listening room because most of these rooms have walls with a hard, reflective nature, only occasion- ally interrupted by curtains, wall art, or drapes.
