Section 1.1—Introduction
From all of us at Wilson Audio Specialties—thank you for purchasing the Alexan-
dria® XLF loudspeaker. The information contained within the pages of this manual will
inform and instruct you as to how you may enhance and prolong the enjoyment of your
Alexandria loudspeaker.
Alexandria XLF joins the Alexandria family, not as a replacement for the Series 2,
but as its even more ambitious sibling. The new XLF clearly resembles the original Al-
exandria’s form factor, but its architecture has evolved to support new technology. It is
physically larger, with 14% greater bass volume. The bass enclosure’s cabinet walls are
thicker for even greater resonance control. XLF refers to the new Alexandria’s Cross Load
Firing port, a unique passive bass management system. Wilson developed a new tweeter
for the XLF. The midrange baffle is constructed from Wilson’s proprietary S-material. Re-
tuned crossovers and a host of parts—each included as a result of exhaustive experimen-
tation and punctilious listening trials. The Alexandria XLF starts from the lofty foundation
of musicality and resolution established by the Alexandria Series 2, and improves upon
its predecessor’s performance in every musical parameter: greater dynamic contrast, bet-
ter harmonic expression, improved and more consistent bass performance room-to-room,
and increased linearity.
Cross Load Firing port system (XLF)
The Alexandria XLF features Dave Wilson’s latest loudspeaker invention: the Cross
Load Firing port (XLF) system. Dave recognizes that his speakers are often installed in
less-than-perfect environments. But as an idealist, he is concerned about how his loud-
speakers perform in the real world. His idealism in this area has been the motivating
force behind many of his inventions, such as adjustable propagation delay, the primary
purpose of which is to optimize, via precise, prescribed adjustment, the performance of
his loudspeakers in actual residential environments.
