•True pistonic operation for
increased freedom from coloration
•Two high-grade Neodymium
magnets placed inside the voice
coil for optimal magnetic shielding
• Copper ring inside the motor’s gap
for modulation control and low
distortion
• Aluminum flux-stabilization ring
for modulation control and reduced
distortion
• Butyl rubber surround for large,
linear excursion capabilities
• Carbon composite aluminum
(CCA) flat-wire voice coil wound on
a 2-inch (50mm) fiberglass
bobbin for low mass and higher
power handling
•Vented center pole for improved heat
dissipation and low compression
CABINET
Reduces cabinet-induced colorations with
1-inch (25mm) thick walls and extensive
internal bracing. For even greater sound
enhancement, rounded baffle edges
minimize diffraction and optimize treble
response. Adjustable spike footing is
attached to the bottom of the cabinet for
optimal stability, accommodating
installations on tile, hardwood, and carpeted
floors.
The cabinet’s wood veneer finish does not
require routine maintenance. However,
cabinet surfaces that have been marked
with fingerprints, dust, or other dirt can be
cleaned using a soft cloth and a highquality furniture polish. If a higher-gloss
finish is desired, a high-quality wax can
also be used.
To clean the cabinet:
1. Apply a high-quality furniture polish
to a soft cloth.
2. Use the cloth to lightly wipe the cabinet
surface.
To clean the grille:
1. Gently vacuum using a soft bristled
brush vacuum attachment.
CAUTION
To prevent cabinet damage, do not use
a cloth made with steel wool or metal
polish to clean the cabinet.To prevent
possible transducer damage, do not
apply furniture polish directly to the
cabinet.
FILTER NETWORK
Optimize loudspeaker on and off-axis
response with high-order filters at 220Hz and
2.8kHz, helping to ensure smooth octave-
to-octave balance and timbral accuracy.
Separate woofer, midrange, and tweeter
filter boards prevent mutual interference
between filter network components,
dramatically reducing distortion over a
wide dynamic range. Removable shortingstraps and gold-plated binding posts
accommodate single-wired, bi-wired, and
bi-amplified connections, while separate
Low Frequency Compensation and Tweeter
Level controls provide precise balance to
compensate for less-than-ideal listening
room acoustics and loudspeaker placement.
WOOFER PORT
Enhances low-frequency extension.
Computer-optimized internal and external
flares minimize distortion resulting from
air turbulence.
