Product Information
Kicker SoloX L7X 8 inch Subwoofer
Overview
The Kicker SoloX L7X 8-inch subwoofer delivers the legendary competition performance of the SoloX family in a compact form factor perfect for space-constrained installations. This third-generation L7X model maintains the same revolutionary engineering that has dominated SPL competitions for over two decades, delivering 800W RMS power handling through a scaled triple-stacked ferrite magnet system while preserving the innovative field-replaceable recone technology that protects your investment under demanding conditions.
Born from the legendary competition heritage of Alma Gates' record-breaking "Beast" Bronco, the compact SoloX 8" continues Kicker's tradition of SPL dominance with installations contributing to systems achieving over 180 dB. The signature square cone design provides 20% more cone area than conventional round 8-inch subwoofers, maximizing acoustic output from the smaller footprint while the proprietary Forced Air Cooling™ technology manages thermal demands in tight installation spaces.
Available in dual 1-ohm (49L7X81) and dual 2-ohm (49L7X82) voice coil configurations, the 8-inch L7X accommodates various amplifier and system designs while maintaining the uncompromising performance standards that have made SoloX the choice of world record holders. This compact option enables serious bass enthusiasts to experience SoloX technology in vehicles and installations where space is at a premium without sacrificing the competition-grade performance legacy.

EBP Calculator
Choosing the right enclosure for your subwoofer isn’t guesswork — it’s science. The Efficiency Bandwidth Product (EBP) is a simple calculation that uses a driver’s Fs (resonance frequency) and Qes (electrical Q) to determine whether it performs best in sealed, ported, or both types of boxes.
- EBP under 50 → Works best in sealed enclosures for tighter, more controlled bass.
- EBP over 100 → Better suited for ported designs where efficiency and output are the priority.
- EBP between 50–100 → Flexible enough to perform well in either design, depending on system goals.
Use our interactive calculator below to compare subwoofers, see where each model falls, and make an informed decision on the best enclosure type for your setup.
Efficiency Bandwidth Product (EBP)
Fs (Hz): 39.6
Qes: .5
Lower EBP → Sealed. Higher EBP → Ported.
