W1v3 12-inch Subwoofer (300 W, 4 )


The 12W1v3 is a lightweight 12-inch driver with excellent performance capabilities at moderate power levels. It features moderate mounting depth with no pole-vent, so the rear of the motor structure can be placed directly against an enclosure boundary. Excellent excursion capability and linearity allow it to reproduce sub-bass with shocking extension and quality. Several of JL Audio's proprietary technologies enhance its performance and reliability.

The 12W1v3-4 is best used with amplifier power in the 75W - 300W range and is optimized to operate in a compact 1.10 cu. ft. (31.5 l) sealed enclosure. Detailed enclosure recommendations can be found in the "Specifications" tab.


Technology

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 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.


Insert Molded Suspension / Coil / Terminal Sub-Assembly (U.S. Patent #7,379,558)

Spiders, voice coils, terminals and lead wires are preassembled, using a patented process, onto a composite carrier for improved precision and reliability.


Engineered Lead-Wire System (U.S. Patent #7,356,157)

Carefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.

Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Electronics can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new electronics should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
