Proline X Performance Optimized Dual 10 inch Ported Box
Professionally Maintained Demo Units
Every demo unit has been carefully maintained by our certified technicians. These aren't customer returns or damaged goods - they're the same high-quality equipment we've used to demonstrate premium sound to our customers for years.
Pre-Tested & Verified
Unlike typical clearance sales, every item has been tested and verified by our technical team. We stand behind the quality of our relocation inventory.
Everything Must Go Pricing
These aren't regular sale prices - this is genuine "moving warehouse" pricing. Discounts you simply won't find under normal retail circumstances.
Trade Show Display Models
Many items are pristine display models from major audio trade shows - equipment that's been seen but never installed. These pieces often include special editions or limited releases not available through regular retail channels.
Proline X Performance Optimized Series - Dual 10" Edition: Double the Power, Amplified Performance
Transform Every Beat Into Pure Thunder - Times Two
Born from precision engineering for Ground Zero subwoofers, our Performance Optimized Series quickly proved its worth across multiple brands. Now your dual 10-inch subwoofers - whatever the make - can achieve the earth-shaking performance they were designed for with the perfect synergy that only comes from matched acoustic loading.
Why Settle for Factory When You Can Have Championship-Level Performance?
Imagine feeling every kick drum in your chest, every bass line vibrating through your bones - now multiply that by two. The Dual 10" Performance Optimized Series doesn't just house your subwoofers - it creates the perfect acoustic environment where two 10-inch drivers work in perfect harmony, delivering the cone area of a 14" subwoofer with the speed and precision that only 10" drivers can provide.

🏆 Engineering Excellence That You Can Hear and Feel
Advanced V-Port Technology
Our proprietary port design eliminates turbulence and port noise, delivering clean, powerful bass that stays tight even at maximum volume - perfectly sized for dual 10" driver airflow dynamics and the increased air displacement of two drivers working in unison.
Military-Grade Internal Bracing
Strategic internal reinforcement prevents panel flex and unwanted resonance, ensuring every watt of power from both drivers translates into pure, undistorted bass. The center divider provides additional structural integrity while optimizing airspace distribution.
Precision CNC Manufacturing
Computer-controlled cutting guarantees perfect 9.15" driver fits and optimal acoustic seal for both mounting positions - no gaps, no air leaks, no compromised performance from either driver.
Professional-Grade Components
From the recessed terminal cup to the interlocking joint design, every component meets professional installation standards for demanding dual driver applications.

For High-End Dual 10" Systems: Achieve the reference-quality sound they were designed to deliver with maximum efficiency
Why Dual 10" is the Performance Sweet Spot:
- Combined cone area equivalent to a 14" driver with 10" speed and precision
- Doubled power handling capability for extreme SPL applications
- Superior heat dissipation with two voice coils and motor structures
- Redundancy - if one driver fails, you still have bass (unlike single driver systems)
- More even bass distribution throughout the vehicle interior
🚗 Universal Dual 10" Compatibility Meets Custom Performance
