7. Midrange (I30 only)
• 3.5-inch (88.9mm) cone constructed
with Organic Ceramic Composite
material
• Die-cast basket to eliminate
coloration from resonances
• True pistonic operation for
increased freedom from coloration
• Two high-grade Neodymium
magnets placed inside the voice
coils for optimal magnetic shielding
• Symmetrical field gap design for
low overall distortion
• 1.5-inch (38.1mm) voice coil
wound on a fiberglass bobbin for
high-power handling and low
distortion
The numbers in Figure 4 (above) correspond with the
numbered items in the Driver Complement section that

• Copper cap stabilizes inductance
and controls flux modulation,
dramatically reducing distortion.
• Optimized and shielded magnetic
circuits to minimize harmonic
distortion and prevent video monitor
interference
FILTER NETWORK
Optimizes loudspeaker on and off-axis
response with a high-order filter at 2.8kHz
for the I20, and high-order filters at 300Hz
and 2kHz for the I30, helping to ensure
smooth octave-to-octave balance and
timbral accuracy. Gold-plated binding
posts accommodate heavy speaker cables,
while separate Low Frequency Boundary
Compensation, High Frequency Level, High
Frequency Tilt and Listener Axis controls
provide precise balance to compensate for
less-than-ideal listening room acoustics
and loudspeaker placement.
