Kicker 11S8L74 Solo-Baric 4 Ohm 8" L7 Square Subwoofer

Features:

• Patented Square-Woofer Technology: The Kicker Solo-Baric L7 woofers continue to be the best sub in their class. The patented square-woofer technology allows for 18% more cone, which translates to more bang for your buck compared to competing round subwoofers. This series features a redesigned and improved SoloKon cone. The enclosure's 4-ohm impedance draws maximum power from your mono amplifier.
• Easy Installation: In addition to the SoloKon™ improvements, the new L7 woofers also provide a much easier installation. The solid pole piece allows more heat sink capabilities and perimeter venting is built into the spider landing unlike previous years. This also allows for a shallower installation as you no longer have to account for venting through the back of the magnet. To make things even easier on the installer, Kicker moved the binding post to the corners of the woofer allowing for an easier connection when running the subs in parallel or series.
• 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 a 8 ohm load.
• 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 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, and 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.
