JL Audio 8W1v3-4 8-Inch 4-Ohm SVC Subwoofer

Ideal for moderate-power, small-enclosure car audio applications, the W1v3 subwoofers share many proprietary features with the premium-line JL Audio models — enabling them to deliver outstanding reliability, superior dynamic stability and low distortion within their intended power envelopes. Plus, their shallow mounting depths and compact motor structures let you extract more bass from less space, compared to other typical woofers in their price range.

• Elevated Frame Cooling^â„¢ technology aids heat dissipation and power handling
• The 10- and 12-inch models pair best with amplifier power in the 75- to 300-Watt range
• The 8-inch subwoofer pairs best with amplifier power in the 50- to 100-Watt range
• Manufacturer’s 1-year warranty

Engineered for performance: Offering impressive output, accuracy and sound quality at moderate power levels, the W1v3 series subwoofers provide an immersive audio experience that can fit comfortably in space-saving enclosures, thanks to the speakers’ shallow mounting depths with no pole vent clearance to accommodate.

Dynamic motor analysis (DMA) optimized speakers: DMA delivers linear motor force over a wide range of speaker excursion and power levels. The result is tight, clean and articulate bass performance with ultralow distortion and stellar sound quality.

Polypropylene Cone Technology: The W1v3 series’ injection-molded, black, mica-filled polypropylene cone structure with rubber surround offers crisp, strong bass output matched with the rigidity and durability to withstand extended play at high volume levels. An aluminum dust cap with the JL Audio logo adds a finishing accent.

Shallow mounting depths: The W1v3 subwoofers’ shallow mounting depths and compact motor structure allow the drivers to comfortably fit in spaces where a typical subwoofer will not. For example, the 10-inch W1v3 needs only 4.6 inches of mounting depth.

Custom accents: To add a personal touch to your subwoofer’s looks, an included trim ring can be painted to match the color scheme of your installation. Optional steel-mesh grille inserts (sold separately) add style and protection for your subwoofer — and the removable trim ring receives these inserts directly to make grille installation a snap.

Powerfully adaptable: On a wide array of vehicle applications, with sealed or ported enclosures, the W1v3 subwoofers deliver superb sound quality and power handling. Both the 10- and 12-inch versions support pairing with amplifiers in the 75- to 300-Watt range. The 8-inch woofer has a 50- to 100-Watt amplifier range.

Elevated frame cooling: The patented JL Audio elevated frame cooling design creates a pathway for high-velocity air to flow directly across the top plate of the speaker voice coil — cooling it for better power handling and improved reliability.

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

FCAM™ technology: This “floating cone attach method” of bonding the surround/cone assembly to the voice coil former/spider structure ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.

Vented Reinforcement Collar: The JL Audio VRCâ„¢ collar design improves the rigidity and stability of the cone/spider/voice coil junction and directs airflow over the voice coil windings for improved thermal performance.

Engineering enhancements are ongoing and may not be reflected in the pictures, videos and specifications.

Specifications

* For one-way linear excursion (Xmax), specs are derived via one-way voice coil overhang method with no correction factors applied.

** All enclosure volumes listed above are net internal volumes! Driver displacement, port displacement and brace displacement must be added to obtain the final gross internal volume. All enclosure dimensions above have already taken this into account. When using multiples in a common enclosure you will need to recalculate the enclosure and port dimensions. For assistance please contact your authorized JL Audio dealer or JL Audio Technical Support.

*** Grille sold separately. See JL Audio SGRU-8 for the 8-inch black steel mesh grille insert available for the 8-inch W1v3 subwoofer (also fits the 8-inch W3v3 model).

JL Audio notes: The enclosure recommendations listed above are external dimensions which assume the use of 3/4-inch (0.75 in; 19 mm) thick material. If you are using 5/8-inch (0.625 in; 16 mm) thick material, subtract 1/4 inch (0.25 in; 6.5 mm) from each dimension. Do not use any material with a thickness of less than 5/8ths inch (0.625 in; 16 mm) as this may compromise the rigidity of the enclosure.

JL Audio recommends the use of this in a bi-amplified system using high-quality satellites and a high-quality amplifier. They do not recommend the use of this with a passive crossover (coil), as this type of device will adversely affect performance.

Due to continual development, product and specifications are subject to change without notice. Garmin, JL Audio and its agents are not responsible for typographical errors.
