Product Information
Experience Groundbreaking Bass Performance with Kicker Solo X 15" Subwoofers
The combination of dual Kicker Solo X L7X 15" subwoofers and our Proline X Professional Series enclosure represents the pinnacle of competition-grade bass performance. This powerful system brings together Kicker's most advanced bass technology with Audio Intensity's precision-engineered enclosure, creating a synergy that delivers unprecedented deep bass at extreme volume levels.
Legendary Kicker Engineering Meets Professional Integration
The Kicker Solo X L7X 15" subwoofers feature a revolutionary design with triple-stacked ferrite magnets surrounding a hyper-extended pole piece, engineered for an enormous and more linear magnetic field. The massive 3-inch voice coils, supported by dual-spider suspension systems, ensure exceptional cone control throughout the entire excursion range. The double-pressed pulp cones with ultra-long-throw Santoprene surrounds utilize Kicker's patented square cone technology with ribbed corners for continuous force and optimal air movement.
Precision-Tuned Proline X Enclosure
Our Proline X Professional Series enclosure perfectly complements the Solo X subwoofers with its massive 10 cubic feet net volume, optimally tuned to 30Hz for maximum output. The enclosure features an impressive 140 square inch port opening that ensures smooth airflow for distortion-free bass at high volumes. Built with triple-layer mounting baffles and extreme internal cross-bracing, this enclosure maintains maximum rigidity even under the most demanding conditions. The flush woofer provision with recessed mounting ensures perfect alignment and professional appearance.
Competition-Ready Performance Features
This system incorporates Kicker's innovative Forced-Air Cooling technology that helps the subwoofers run significantly cooler for enhanced reliability during extended high-power operation. The unique SoloX terminals simplify wiring with spring-loaded connections that accept up to 8 AWG wire, plus dual 8 AWG terminal blocks for easy series or parallel configuration. With recommended power handling of 1000-2000 watts RMS per subwoofer, this dual configuration can handle up to 4000 watts RMS total – perfect for competition-level performance.
Substantial Build Quality Requires Freight Shipping
Due to the extraordinary build quality and massive construction of this competition-grade system, the complete package weighs over 300 pounds. This substantial weight is a testament to the premium materials used – from the triple-layer MDF baffle construction to the extreme internal bracing and the hefty triple-stacked ferrite magnets in each Solo X subwoofer. Given this significant weight, standard ground shipping isn't suitable, and freight delivery is required to ensure safe transport. We're pleased to include freight shipping at no additional cost, delivering this powerhouse system directly to your location. The freight carrier will contact you to schedule delivery, and we recommend having assistance available to help unload this substantial package.
Fully Loaded, Pre-Wired, and Ready to Install
Your Kicker Solo X dual subwoofer system arrives as a complete, turnkey solution – fully loaded and professionally pre-wired for immediate installation. Solo X 15" subwoofers come pre-mounted in the Proline X enclosure using precision threaded inserts, with all internal wiring completed using premium 8 AWG oxygen-free copper wire. The high-output terminal cup is already connected to both subwoofers, configured for your specified impedance requirements. Connect your amplifier's speaker wires to the terminal cup, and you're ready to experience competition-level bass. This plug-and-play approach eliminates installation guesswork and ensures optimal performance from the moment you power up your system. Every connection has been professionally completed and tested before shipping, giving you confidence that your investment is ready to perform at its peak right out of the crate.
