Multielement Expanding Array
Months of study and computer simulation resulted
in a scientifi cally designed three-element array with
idealized dispersion characteristics. The XA’s perfor-
mance is seamless and invariant within any likely
listening position. Controlled directivity beyond
normal vertical angles reduces room involvement,
for a clearer and more detailed image with either
movie or multichannel music sources.

Integral Powered Subwoofer
An integral subwoofer gives the low-frequency
foundation necessary for music or cinema reproduc-
tion (XA75LE). Inclusion of an amplifi ed subwoofer
allows the upper-range drivers to be optimized for
higher sensitivity.

Controls for Subwoofer Optimization
Controls on the dedicated subwoofer amplifi er allow
optimization of subwoofer performance to both
the room and program. Parametric Equalization
(XA75LE) allows correction of room acoustic fl aws.
Bass level and subwoofer rolloff shape controls
(via remote in the XA75LE) allow for adjustment as
needed for program material, room, and taste.

Platform Baffl e
This three-layer sandwich isolates the baffl e from
the cabinet to decrease panel resonances and
coloration—especially in the critical midrange. The
Platform Baffl e consists of materials of varying
density—an extremely dense outer layer to which
the tweeter and bass units are mounted, a “squishy”
neoprene middle layer, and a medium-density inner
layer that attaches to the cabinet.

Radiused-Edge Baffl e
The elliptical radius on our baffl e edge reduces re-
radiation for a cleaner and smoother response—es-
pecially off-axis. Snell pioneered this technique in
the original Type A speaker system in 1976.
