The 12W0v3 is a rugged performer with excellent efficiency, excursion capability and linearity. Its overall performance envelope that puts it right at the top of its price class. It features a beefy 2 in. diameter voice coil and our patented Elevated Frame Cooling design for enhanced power handling and reliability.
The 12W0v3 is best used with amplifier power in the 75W - 300W range and is optimized to operate in a moderately sized 1.375 cu. ft. (38.9 l) sealed enclosure, or a 1.75 cu. ft. (49.6 l) ported enclosure. Detailed enclosure recommendations can be found in the "Specifications" tab.
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.DMA is able to analyze the real effects of fluctuating power and excursion upon the magnetic circuit of the motor, specifically the dynamic variations of the "fixed" magnetic field.
This delivers intensely valuable information compared to traditional modeling, which assumes that the "fixed" field produced in the air gap by the magnet and the motor plates is unchanging.
DMA not only shows that this "fixed" field changes in reaction to the magnetic field created by current flowing through the voice coil, but it helps our engineers arrive at motor solutions that minimize this instability.
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. JL Audio's patented design improves upon this cooling technique in a number of ways.
By elevating the frame above the top-plate of the motor (via stand-offs integrated into the bottom of the frame) a narrow, high-velocity air-path is created between the bottom surface of the frame and the top surface of the top-plate.
This air path leads directly to the voice coil and then turns upward into the spider air cavity. By utilizing the pumping action of the spider through this focused air path, a large volume of cool air hits the coil windings directly.
