Proline-X Performance Wedge Series

The Proline-X Performance Wedge Series subwoofer boxes are engineered for tighter trunk installs without sacrificing output. Designed with an angled back panel, these enclosures push snugly against the rear seat in hatchbacks, sedans, and coupes. Each model is built from our upgraded Generation III platform, featuring a high-power terminal cup, pre-wired 12-gauge OFC wiring, and the structural strength of V-joint construction. Available in plush black carpet or charcoal trunkliner, these wedge subwoofer boxes combine form, function, and fitment.

All About the Proline-X Performance Wedge Series

The Performance Wedge Series is the next evolution of the Proline-X Performance enclosure lineup, offering a more vehicle-friendly footprint without compromising acoustic performance. These angled-back enclosures are optimized for trunk applications, where the rear seat often limits usable space. By slanting the rear panel, the box nestles closer to the backrest, allowing more cargo depth and easier placement.

Key Features of the Wedge Series:

• Angled Rear Panel for improved trunk fitment
• High-Power Binding Post Terminal rated for large-gauge wire and strong clamping force
• Factory pre-wired with 12-gauge OFC speaker wire for fast, clean installation
• V-Joint CNC Assembly adds more glue surface area for stronger, more rigid seams
• Finish Options: Plush Black Carpet for a refined look, or Charcoal Trunkliner for factory match
  

This series is available in multiple sizes and configurations to fit a wide range of systems:

• Single 8", 10", 12", 15"
• Dual 8", 10", 12", 15"
• Triple 8", Triple 10"
  
  Every enclosure is designed with sealed or ported tuning in mind (model-dependent), and tuned to deliver strong low-end performance while maintaining responsiveness. Whether you're focused on SQ, SPL, or just looking to cleanly install your subs in a sedan, the Performance Wedge Series gives you an edge in both fitment and sound.
