Product Information

W3v3 10-inch Subwoofer (500 W, 4 Ω)

This acclaimed Subwoofer strikes an outstanding balance in power handling, enclosure requirements and excursion to deliver excellent results in medium power applications. Several exclusive JL Audio technologies and proprietary assembly techniques are applied to the 10W3v3 to enhance linearity and reliability.

The 10W3v3-4 is best used with amplifier power in the 150W - 500W range and is optimized to operate in a compact 0.625 cu. ft. (17.7 l) sealed enclosure, or a 1.125 cu. ft. (31.9 l) ported enclosure. Detailed enclosure recommendations can be found in the "Specifications" tab.

Dynamic Motor Analysis - DMA Optimized Motor

JL Audio's proprietary Dynamic Motor Analysis system is a powerful suite of FEA-based modeling systems, first developed by JL Audio in 1997 and refined over the years to scientifically address the issue of speaker motor linearity. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.

Elevated Frame Cooling 

JL Audio's patented Elevated Frame Cooling design delivers cool air through slots directly above the top-plate to the voice coil of the speaker. This not only enhances power handling, but also sound quality by minimizing dynamic parameter shifts and power compression.

Floating Cone Attach Method - FCAM™ 

This assembly technique, conceived by JL Audio, ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.

Vented Reinforcement Collar

JL Audio's Vented Reinforcement Collar (VRC®) improves the rigidity and stability of the cone/spider/voice coil junction and directs airflow over the voice coil windings for improved thermal performance.

* Xmax specifications are derived via one-way voice coil overhang method with no correction factors applied.

** Efficiency (1 W / 1 m) is not an accurate indicator of a subwoofer’s output capability and should not be used as a comparison to other subwoofers to determine which one is “louder”.
