    An instructional video outlining the Wilson Audio Setup Procedure ( WASP) can be found here: wilsonaudio.com/WASP. The proper positioning of your new Alexia Series 2 within your room is critical in order to extract its formida- ble per formance envelope. When carefully followed, the WASP has proven to be the most effective method for setting up Wilson loudspeakers.

At the point where you begin to hear the reflected sound of your voice, you have reached the outer edge of the Zone of Neutrality.

    The location of your listening position is as impor tant as the careful setup of your Wilson Audio loudspeakers. The listening position should ideally be no more than 1.1 to 1.25 times the distance between the tweeters on each speaker.

  • Page 11: S P E A K E R O R I E N T A T I O

    This can cause out-of-phase cancellations, or comb filtering, which will cancel some frequen- cies and change the tonal balance of the music. Adhering to the Wilson Audio Setup Procedure outlined in the previous section is the best method with which to position your loudspeakers.

By measuring the distance from the speaker to your ear (mea- sured from the bottom/front of the woofer to directly below the ear canal) when seated in the listening position, as well as height of the listener ’s ear (the dis- tance from the floor to the center of the ear canal), you will be able to align the system for your listening position.

    Procedure (WASP) outlined in Sec tion 1. Before the spike/diode assemblies are attached to the bottom of Alexia Series 2 , the set up and fine tuning of your loudspeaker should be completed. Before spiking Alexia Series 2 , use masking tape to carefully mark their location.

    Note: Do not tighten these assembled spikes. You will need to unscrew them when you level the Alexia Series 2. This will ensure that if for any rea- son you have to remove Alexia Series 2 spikes, you will be able to withdraw the set screw using the supplied Allen wrench.

    12. Taking care obser ve the location of the woofer module to the masking tape used during the WASP setup marking the precise location of Alexia Series 2’s position, return the module to an upright position. 13. Re -install the Upper Array atop the Woofer Module.
  • Page 39 Alexia Series 2 is level left to right. Place a level on the front to back oriented axis. If it is level, then Alexia Series 2 is level. If the Alexia Series 2 is leaning one way or the other, following the same process as above, length- en the appropriate spikes on the front or rear of the Woofer Module until the Alexia Series 2 is level.

    Section 4.3—Removing the Protective Film To protect the finish of the Alexia Series 2 during final manufacture, ship- ment, and setup in your listening room, we have applied a removable layer of protective film over the finish. We recommend that this film be left in place un- til the speakers are in their final location in your listening room.

The back cover is secured by four pres- sure -fit pins, and requires no tools to remove.

    Note: Only Wilson Audio replacement resistors should be used in your Alex- ia Series 2s. Changing the value or brand of resistor will have a deleterious af fec t on the sonic per formance of your loudspeakers and will void your Wilson Audio Warrant y.
