y Blackened One Piece Uniplate
with Vented Hyper-Extended Pole
1.
Provides enhanced heat transfer for cool operation and maximum power handling. The heat is transferred
from the pole piece to the back plate, effectively acting like a radiator in an engine. This lowers the operating tem-
perature of the voice coil. Note:The increase in temperature increases the impedance of the speak-
er. This results in lower output and is referred to as Power Compression.
2.
Reduces non-linear magnetic fields around the voice coil gap for superior cone motion control. The
extended pole assures the voice coil is always in the magnetic field when moving peak to peak. When the speaker
reaches it’s Xmax, the voice coil is still in the gap between the pole piece and magnet structure due to its extended
pole-piece.
3.
Releases pressure under ISD for freer cone motion and enhanced low frequency response. Air trapped
under the ISD is forced out though the pole-piece to allow the cone to move freely. Heat and pressure build up
under the ISD and need to be released to allow the speaker to function properly.
y High-Temp Kapton® Voice Coil Former Heat is the primary enemy to the life of a speaker, which is one of
the reasons we use Kapton® voice coil formers. Kapton® is a man-made product that is light, durable and heat-
resistant. The Kapton® former acts as an insulator to keep the heat of the voice coil from breaking down the adhe-
sive that connects the voice coil to the cone. During high excursion and prolonged exposure to heat, the Kapton®
former holds its shape and does not expand or contract. As a bonus, Kapton® is also a very quiet material and dur-
ing operation, does not discolor the music by adding unwanted sound.
y ISD (Inverted Structural Dome
))
Kicker was one of the first companies to switch to the Inverted Structural
Dome. We have designed a cone with a groove for the ISD to lock into, further adding strength to structure. When
a cone reaches it’s peak it wants to buckle because it’s momentum keeps it moving out. The ISD provides structur-
al support for the cone to resist buckling. NOTE: When the cone buckles, the output of the woofer decreases.
Therefore, the ISD is not just a cosmetic thing, it is an integral part of the woofer to maintain it’s maximum per-
formance.
y Stitched Surround A signature of KICKER woofers has always been the stitched surround. It prevents the sur-
round from separating from the cone at high excursions. When the woofer is moving back and forth it puts a lot
of strain on the adhesive that is holding the surround to the cone and often causes the two to separate. Stitching
the surround to the cone eliminates this from happening.
If stitching were inexpensive, everybody would do it!
y
Dual Ultra-Length Voice Coils A speaker can obtain extreme Xmax only when the voice coil is long enough
and can sustain the stress. Dual voice coils give the installer the option of several different wiring configurations
compatible with any amplifier.
In addition, the S15L7 has Dual spiders to help control the massive structure!
y Sleeved High-Power Tinsel Lead Wires Resist lead breakage and power robbing resistance losses under
demanding conditions. When a speaker is being pushed to it’s limits there is a lot of strain being put on the leads,
especially on high performance woofers like the Solo-Baric® L7. Sleeving tinsel leads help strengthen them to resist
breakage.

Spring-Loaded Nickel Plated Terminals On a High Performance speaker like the Solo-Baric® L7, you would
expect nothing less than a High Performance terminal. They allow the installer to use the maximum gauge wire to
minimize power losses for the ultimate Ground Poundin’ system.
