Overview

Our take on the JL Audio 8W1v2-4

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 8W1v2-4 8" 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.


Priced per speaker

I bought this to replace the factory sub in my 2001 Tahoe. Had to cut the outer rubber trim on the speaker, but once that was done, it was a nice tight fit in the stock enclosure. I paired this with the Rockford Fosgate R150X2 amp and I couldn't be happier. The bass is awesome.

Features

Woofer: JL Audio W1v2 subwoofer features an injection-molded, metallic-finish polypropylene cone woofer with an embossed metallic JL Audio logo with a butyl rubber surround for added durability, woofer excursion and bass response.

Surround Stress Relief: By creating a radius 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

Interlocking Cone & Dust Cap: The W1v2's utilize 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.

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.

Vented Reinforcement Collar: The Vented Reinforcement Collar (VRC) is a composite structure that addresses two issues related to reliability.

  • Stress Relief: By reinforcing the critical junction between the cone, voice coil and spider, the VRC greatly reduces failures due to glue breakdown or material weakness. It does this by greatly increasing adhesive contact area and providing stress relief to the spider material at excursion extremes
  • Air Flow: The VRC also features slots that facilitate air flow directly onto the voice coil windings. This reduces thermal compression effects and enhances reliability

Insert Molded Suspension/Coil/Terminal Sub-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. This type of assembly ensures precise lead wire length, lead wire entry and exit angles; and coil to spider perpendicularity.

Elevated Frame Cooling System: The elevated frame design of the W1v2 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.

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.

Recommended Sealed Box Volume: The sealed box size recommended by JL Audio is 0.375 cu/ft. A diagram is provided in the owner's manual for a sealed box with external dimensions of 10.5" W x 10.5" H x 7.75" 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 0.50 cu/ft. A diagram is provided in the owner's manual for a sealed box with external dimensions of 12.5" W x 10" 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.) A round port is recommended with the following dimensions: Diameter = 2", Length = 10"
