Features
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.
Square Design: By making the Solo-Baric square, Kicker is giving
you the most possible cone area (Sd) for a given size baffle, 16% to 20% more area
than a conventional round subwoofer. More cone area means the Solo-Baric L7 moves
more air, resulting in louder, deeper bass.
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 improves 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.
Voice Coils: The dual ultra length 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 following benefits:
- Optimizes heat transfer efficiency for cooler operation
and maximum power handling capability
- 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 the
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.
Speaker Terminals: The terminals are spring loaded and nickel
plated for solid connections with speaker wire up to 10 gauge.
Break-in Period: 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 two 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.
Enclosure Compatibility
Recommended Sealed Box Volume:
- Compact (minimum enclosure volume): 1.25
cubic feet
- SQ (maximum enclosure volume): 2.0 cubic
feet
Recommended Vented Box Volume:
- Compact: 1.75 cubic feet; 2.5"
x 13.25" port opening; 22.5" port length

Cutout: The woofer will not mount in a standard enclosure
with a round cutout. Instead, the woofer must be mounted in an enclosure with
a 11.048" x 11.048" square opening.
