Connect your amplifier's output to the terminal cup and experience competition-level bass performance. This turnkey approach eliminates installation errors and ensures your system performs at its peak from day one.
Freight Shipping Information
Due to this professional-grade system's substantial weight and size, this bundle requires freight shipping to ensure safe delivery. The complete package weighs approximately 150 pounds when fully assembled, with the massive triple-stacked ferrite magnet structure alone accounting for over 25 pounds. The enclosure's robust construction and internal bracing add significant weight, bringing the total shipping dimensions to 42" x 20" x 25" and requiring specialized handling. We've included freight shipping in the listed price, providing door-to-door delivery via professional freight carriers who specialize in handling high-value audio equipment. Your investment will arrive properly palletized and protected, ready for installation.
Triple-Stacked Ferrite Magnet Structure
The revolutionary motor design features three massive ferrite magnets surrounding a hyper-extended pole piece, creating an enormous linear magnetic field. This configuration provides exceptional heat dissipation and maintains consistent performance even under extreme power conditions.
Forced Air Cooling™ Technology
Kicker's proprietary cooling system actively manages heat dissipation, allowing the SoloX to run significantly cooler during extended high-power operation. This technology ensures sustained performance during competition runs and prevents thermal compression.
Field-Replaceable Recone Assembly
The exclusive no-glue recone kit features a pre-assembled cone, voice coil, and spider assembly with bolt-on installation. Using the surround compression system and alignment shims, repairs take minutes instead of hours, keeping you in the competition.
Square Cone Technology with Ribbed Corners
The patented square design provides 16-20% more cone area than round subwoofers of similar size. Ribbed corners ensure consistent flex patterns and continuous force distribution for maximum excursion without distortion.
Dual Spider Suspension System
Two high-strength spiders mounted on engineered landing zones provide exceptional cone control throughout the excursion range. This design maintains linearity at extreme volumes while preventing mechanical damage.
Advanced Terminal Configuration
Spring-loaded terminals accept up to 8 AWG wire, complemented by dual 8 AWG terminal blocks for flexible wiring options. This system simplifies series/parallel configurations for multiple subwoofer installations.
Triple-Layer Mounting Baffle
The mounting surface features three layers of 3/4" MDF laminated together, creating a 2.25" thick baffle that eliminates flex under extreme power conditions. This design ensures a perfect seal and prevents energy loss.
Advanced Internal Bracing
Strategically placed cross-bracing throughout the enclosure maintains structural integrity at competition SPL levels. The bracing pattern is optimized to prevent standing waves while maximizing internal volume.
Precision Port Design
The massive 70 square inch port opening ensures smooth airflow without turbulence, even at maximum excursion. Computer-optimized port length and flare design eliminate port noise and compression.
Professional Terminal Cup
Dual High-current terminal cup accepts up to 8g speaker cables and features gold-plated connections for maximum conductivity.
Custom Acrylic Branding
Laser-etched acrylic inserts add professional aesthetics while allowing for personalization options. The high-gloss finish complements any installation.
Show-Quality Finish
Premium plush carpet provides durability and acoustic dampening while maintaining a professional appearance. All edges are precisely wrapped with no visible seams.
Frequently Asked Questions
What makes the Kicker SoloX L7X different from other subwoofers?
The SoloX L7X features patented square cone technology providing up to 20% more surface area than round subwoofers, triple-stacked ferrite magnets for extreme power handling, and exclusive Forced Air Cooling that allows sustained high-power operation. The field-replaceable recone kit ensures you can service the subwoofer quickly without specialized tools or adhesives.
Why is the Proline X enclosure better than generic boxes?
The Proline X is specifically engineered to Kicker's exact specifications for the SoloX series. It features precision 30Hz tuning, a massive 70-square-inch port opening, and triple-layer baffle construction. The extreme internal bracing and CNC precision cutting ensure optimal acoustic performance, while the professional-grade materials and finish provide competition-level durability.
Can I use this setup for daily driving or is it competition only?
While designed for competition, this combination excels in daily use when adequately powered. The 30Hz tuning provides excellent musical bass reproduction, and the robust construction ensures years of reliable performance. Many enthusiasts use this setup for both street and competition applications.
What size alternator do I need for this system?
We recommend a minimum 250-amp high-output alternator for optimal performance at full power. The actual requirement depends on your amplifier choice and listening habits. Competition use may require 300+ amp alternators and additional batteries for voltage stability.
Will this fit in my vehicle's trunk?
The enclosure measures 40" W x 18" H x 22.75" D and requires adequate space for installation. Most full-size SUVs, large sedans, and crew cab trucks can accommodate this enclosure. Measure your available space carefully, accounting for clearance around the port opening.
How difficult is the recone process?
The SoloX L7X features a revolutionary field-replaceable recone kit that requires no glue. With basic tools and the included alignment shims, most users can complete the process in under 30 minutes. This makes it ideal for competition use, where quick repairs are essential.
Does the square design affect sound quality?
The square design actually improves bass performance by providing more cone area and consistent excursion patterns. Kicker's patented ribbed corners ensure the cone moves uniformly, preventing distortion while maximizing output. Many SPL world records have been set with square subwoofers.
