About the JL Audio 12W1v2-4

The affordable W1v2 subwoofer incorporates patented features developed by JL Audio for their legendary W7 subs. Special venting keeps the W1v2 sub running cool for trouble-free performance, while extensive research in cone bonding and motor assembly construction keeps its cone movement linear for precise, dependable output. The cone interlocks with the dust cap for superior rigidity, and a sophisticated suspension system keeps internal parts aligned properly.

The low-profile 12W1v2-4 12" subwoofer works best in compact enclosures, so you can put quality lows in smaller and hard-to-fit vehicles. It features a metallic-finish polypropylene cone with an embossed JL Audio logo for a look that stands out as much as the sound. The removable, customizable trim ring lets you put a personal touch on your system, and makes optional grille installation a snap. This punchy W1v2 sub works well with moderate power, delivering impressive performance without costing a fortune.

Features

Dynamic Motor Analysis (DMA): DMA is JL Audio's proprietary method aimed at improving dynamic motor behavior. As a result of DMA optimization, W1v2 motors remain linear in motor force over a very long range of excursion, and also maintain a highly stable fixed magnetic field in the gap over a wide power range. The result is vastly reduced distortion, faithfully reproduced transients, and tight, clean, articulate bass.

Floating Cone Attachment Method (FCAM): JL Audio's patented FCAM technology is an innovative method of bonding the surround/cone assembly to the voice coil/spider assembly. This assembly technique ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.

Interlocking Cone and Dust Cap: In conventional designs, the dust cap is simply glued onto the cone to cover the coil/gap area and create a seal between the enclosure and the listening environment. The W1v2 utilizes a dust cap that is not just glued, but also interlocks with features molded into the cone body for a tight snap-fit. This creates a more rigid cone assembly and a more reliable dust cap attachment.

Vented Reinforcement Collar (VRC): The Vented Reinforcement Collar is a composite structure that addresses two issues related to reliability. By reinforcing the critical junction between the cone, voice coil and spider, the VRC greatly reduces failures due to glue breakdown or material weaknesses. It does this by greatly increasing adhesive contact area and providing stress relief to the spider material at excursion extremes. the VRC also feature slots that facilitate air flow directly onto the voice coil windings to reduce thermal compression effects and enhances reliability.

Spider/Lead Wire Assembly: The W1v2 features a unique spider, coil and terminal subassembly which is assembled prior to installation in the speaker frame for optimum alignment and glue-joint integrity. The spider is insert-molded into a composite carrier tray which also incorporates the terminal assembly and lead wire strain relief features for enhanced reliability and optimal alignment of parts. The flying lead wires are carefully controlled and strain-relieved without resorting to woven-in lead wires, which can degrade spider performance.

Elevated Frame Cooling: The elevated frame design of the W6v2 delivers high-velocity air flow 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.

Surround Stress Relief: By creating a radiused feature on the edge of the cone, stress is relieved from the surround material at maximum forward excursion, resulting in longer life and more consistent surround behavior.

Customizable Trim Ring: The woofer comes with a removable ring made of black ABS plastic which can be painted to match the installation theme and create a personalized look. You can purchase optional grille mesh inserts which are specifically designed to fit into the inner diameter of the trim ring.

Removable Magnet Boot: The woofer magnet has a removable protective rubber boot. The magnet diameter listed in Features & Specifications (4.721") was measured with the rubber boot removed. With the boot installed, the magnet diameter becomes 5.036".

Recommended Sealed Box Volume: The sealed box size recommended by JL Audio is 1.25 cu/ft. A diagram is provided in the owner's manual for a sealed box with external dimensions of 17.5" W x 15.5" H x 11.5" D, assuming 3/4" thick material. (If you are using 5/8" thick materials, you should subtract 1/4" from each dimension.)

Recommended Ported Box Volume: The ported box size recommended by JL Audio is 1.75 cu/ft. A diagram is provided in the owner's manual for a sealed box with external dimensions of 19.75" W x 16" H x 17" D, assuming 3/4" thick material. (If you are using 5/8" thick materials, you should subtract 1/4" from each dimension.) A slot port is recommended with the following dimensions:

  • Slot Width =1.5"
  • Slot Height =14.5"
  • Slot Length =33.75" (a right angled port with a 14.5" extension)
