Product Information
W3v3 8-inch Subwoofer Driver (250 W, 4 Ω)
If you need an 8-inch subwoofer that can create outstanding bass in extremely small enclosures, the 8W3v3 will do the job and surprise you with its power and accuracy. It employs the same technologies as its larger diameter brethren to deliver a whopping 0.375 in. (10 mm) of controlled, one-way, linear excursion.
The 8W3v3-4 is best used with amplifier power in the 75W - 250W range and is optimized to operate in a tiny 0.30 cu. ft. (8.5 l) sealed enclosure, or a 0.35 cu. ft. (9.9 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.
