Dual Voice Coils: For increased
system flexibility, the woofer has two 4 ohm voice coils. When the voice coils
are wired in parallel, the woofer presents a 2 ohm load. When the voice coils
are wired in series, the woofer presents an 8 ohm load. In addition, each coil
may be connected to a different amplifier channel and each channel will see a 4
Square Design: By making the
Solo-Baric square, Kicker is giving you the most possible cone area (or Sd) for
a given size baffle, 16% to 20% more area than a conventional subwoofer. More
cone area means the Solo-Baric L7 moves more air, resulting in louder, deeper
Cone Material: The square SoloKon design is a unique one-piece construction, using
polypropylene material that moves as a lightweight piston, for improved control.
The cone remains rigid, minimizing cone flex and distortion. A rear cone brace
integrates into the cone with a continuous contact perimeter weld, which offers
unmatched strength and resistance to deformation under pressure.
Surround: The tough, flexible
Santoprene rubber surround has a long-throw, positive-roll design, which
controls extreme cone excursion and is highly tear-resistant. The corners of the
surround are ribbed to ensure linear cone motion. The surround is stitched to
the reinforced cone edge, making separation between them virtually impossible,
even in the harshest conditions.
Spider: The woofer is equipped
with a wide poly-cotton spider which easily handles high cone excursions due to
its increased diameter and unique shape.
Enhanced BAM (Basket And
Motor) Assembly: The Solo-Baric L7 utilizes a high strength stamped steel
basket which features a low-profile open design and provides a solid foundation
for the precision-aligned motor assembly. Perimeter venting in the BAM relieves
pressure from under the spider, supports linear excursion, and helps dissipate
heat from the voice coil and motor structure.
Dual Voice Coil: The dual ultra
voice coils sustain enormous cone excursion and provide flexible impedance
matching options. The high-temperature Polyimide Film Voice Coil former improves
sonic and conducive properties, and prevents thermal-electrical meltdown. The
voice coils are rated to 220° Celsius.
UniPlate Construction: The
Solo-Baric L7 features a one-piece UniPlate construction with a vented
hyper-extended pole piece and backplate. This unique design provides the
- Optimizes heat transfer
efficiency for cooler operation and maximum power handling ability.
- Eliminates erratic magnetic flux
from the voice coil gap.
- Releases pressure under the
suspension for uniform cone movement and responsive low bass.
- Prevents the voice coil from
bottoming out and corresponding damage.
Tinsel Lead Wires: The sleeved,
high-power tinsel lead wires eliminate broken leads and power loss, due to the
common use of "insufficient-gauge" lead wires. The lead wires are terminated
with multiple polymer-based strain-relieving mechanical fasteners.
Rubber Magnet Boot: A black
rubber boot covers the outside edge of the magnet structure to improve the
cosmetics of the woofer and protect the magnet from chipping or breaking during
Speaker Terminals: The
terminals are spring loaded and nickel-plated for solid connections with heavy
Due to the complex nature of Kicker Solo-Baric L7 woofers, they require a
break-in period in order to produce optimum low-bass response. The
high-performance suspension system makes the speakers very stiff
"out-of-the-box". Approximately 2 weeks of daily playing will allow
the suspension to break-in and reach its optimum equilibrium. A
"broken-in" subwoofer will exhibit stronger bass performance, smoother
response, and greater low-bass extension.
Power Handling: The
power handling specifications differ according to the type and size of the
enclosure. The power handling specifications assume that both voice coils are in
use. Note: Both voice coils in a dual voice coil speaker should always be
Recommended Sealed Box
Volume: When mounted in a sealed enclosure, the woofer delivers massive
amounts of high-impact bass and can be driven with punishing levels of amplifier
- Compact (minimum enclosure
volume): 0.88 cu/ft; the woofer can handle up to 750 watts RMS (375
watts per voice coil)
- SQ (maximum enclosure volume):
2.0 cu/ft; the woofer can handle up to 750 watts RMS (375
watts per voice coil)
Recommended Vented Box Volume: The vented enclosures incorporate massive slot-loaded ports
with ultra-low air velocity and hard-hitting bass. These are not your
traditional port tubes; the slot-loaded ports are integrated into the enclosure
- Compact: 1.75 cu/ft;
2.5" x 13.25" port opening; 22.5" port length; the woofer can
handle up to 600 watts RMS (300 watts per voice coil)
- SPL/Deep Bass:
3.25 cu/ft; 3" x 13.25" port opening; 14.5" port length; the woofer can handle
up to 600 watts RMS (300 watts per voice coil)
Note: The power handling
specifications listed with the vented enclosure recommendations apply only
when a 25Hz, 24dB/octave subsonic filter (sold separately) is used with this
woofer. If a subsonic filter is not used, power handling may decrease, excessive port noise can occur,
and the life of the woofer may be shortened.
The woofer will not mount in a standard enclosure with a round cutout. Instead,
the woofer must be mounted in an enclosure with a 11-1/16" x 11-1/16" square
