The XA Series of products is an “ultra” high-performance 
speaker line utilizing a unique expanding array format 
(XA). This array was created after several months of 
intensive computer modeling and study, with a serious 
review of what is appropriate for both music and home 
theater usage. With the new XA75LE Snell engineers 
have created a three-element array with virtually no 
change in response through ±15 degrees vertically, yet 
a desirable, signifi cant drop in response at 30 to 45 
degrees above or below axis. There is virtually no varia-
tion within a likely listening window, but a signifi cant 
reduction in energy of the fl oor and ceiling bounce...
which creates a reduced reverberant fi eld for a clearer, 
more articulate sound. This design approach is not only 
benefi cial to the movie lover, but is also much more 
appropriate for multichannel music listening with the 
latest discrete music formats.\

All XA products feature a high degree of “environment 
tunability” with boundary switches and treble switches. 
THe XA75LE also has subwoofer level and rolloff adjust-
ments and even a parametric equalizer. They are all 
magnetically shielded for use near video monitors.

The XA products also feature stunning styling that is 
fully integrated with their acoustical function.
