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.
