Alexandria X-2 Series 2 - Wilson Audio

A l e x a n d r i a X - 2 S e r i e s 2 O w n e r ’ s M a n u a lChanging the value or brand of resistor will have a deleterious affect on the sonic performanceof your loudspeakers and may void your Wilson Audio Warranty.Midrange and Front Tweeter ResistorsThe Midrange Level and Front Tweeter Level resistors provide precise level matchingfor the midrange and tweeter drivers correspondingly. The resistors also act as ultra highquality fuses which open before a driver can be damaged by excess power. See Section6.0 for details in replacing these resistors in the event one of these two resistors is damaged.Additionally, these two resistors can be usedto tailor the output of the corresponding driverto overcome tonal balance issues that result fromroom acoustics. Refer to Figures 23 through 25 forinformation important to this adjustment.Midrange Phase ResistorsThe Midrange Phase resistor is a propagationdelay tuning device and should never be changedor altered by the user.Woofer Damping ResistorThe Woofer Damping resistor affects the waythe Alexandria’s woofers couple to the amplifier.Generally, for direct coupled, solid state amplifiers,the Light Damping resistor (27.3 ohms) shouldbe used. With tube amplifiers, the Medium Dampingresistor (23.4 ohms) should be used (see Figures23 through 25).Figure 25 - Resistor Plate64Wilson Audio Specialties
