*Xmax specifications are derived via one-way voice coil overhang method with no correction factors applied.

**Efficiency (1W/1m) is not an accurate indicator of a subwoofer’s output capability and should not be used as a comparison to other subwoofers to determine which one is “louder”.

***Re (DC resistance) is measured with the voice coils in series, for parallel-wired specification divide Re by 4. All other specifications remain the same.

Prolonged exposure to sound pressure levels in excess of 100dB can cause permanent hearing loss. This high-performance speaker can exceed this level. Please exercise restraint in its operation in order to preserve your ability to enjoy its fidelity.

When installing a subwoofer in your vehicle, it is extremely important to secure the enclosure firmly. We recommend bolting the enclosure through the metal of the floorpan or the frame of the vehicle with large diameter washers for reinforcement. If an enclosure is not firmly attached, it can become a projectile in a collision. This is particularly important in a hatchback, station wagon, sports utility vehicle, or van.

The enclosure recommendations listed above are external dimensions which assume the use of 3/4" (19mm) thick material. If you are using 5/8" (16mm) thick material, subtract 1/4" (6.5mm) from each dimension. Do not use any material with a thickness of less than 5/8" (16mm) as this may compromise the rigidity of the enclosure.

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 acount.

When using two subwoofers in a common enclosure simply double the required volume and, in the case of a ported enclosure, use two times the recommended port(s). Likewise, when using three subwoofers in a common enclosure simply triple the required volume

and, in the case of a ported enclosure, use three times the recommended port(s).

We recommend the use of this speaker in a bi-amplified system using high-quality satellite speakers and a high-quality amplifier. We do not recommend the use of this subwoofer with a passive crossover (coil), as this type of device will adversely affect performance.

All specifications are subject to change without notice.

10W3, 8W3 specifications

JL Audio is a brand synonymous with high-quality audio components, and its W3 series of subwoofers, specifically the 8W3 and 10W3 models, embody the company's dedication to performance and innovation. The W3 series is designed for car audio enthusiasts who prioritize deep bass and clarity in their sound systems.

The JL Audio 8W3 is an 8-inch subwoofer that packs a punch despite its compact size. It features a robust construction with a polypropylene cone that ensures durability and effective sound reproduction. The 8W3 employs a unique, patented “VRC” (Ventilated Reinforcement Collar) and “Dynamic Motor Analysis” technologies to minimize distortion and optimize the magnetic field. This results in clearer bass tones across a wide range of frequencies. With a peak power handling capacity of 1000 watts and a recommended RMS power of 300 watts, the 8W3 delivers impressive performance, making it ideal for small to mid-sized vehicles.

On the other hand, the 10W3 offers a larger, more powerful alternative for those seeking deeper bass. The 10-inch subwoofer is engineered with a similar focus on sound quality, featuring a stiff yet lightweight cone, ensuring it performs well even at higher volumes. Like its smaller counterpart, the 10W3 incorporates JL Audio’s advanced “Cast Alloy Frame” to provide rigidity and enhance cooling. This model can handle peak power of up to 1200 watts, with an RMS rating of 500 watts, allowing for deep, resonant bass that can fill larger vehicles and spaces.

Both the 8W3 and 10W3 subwoofers utilize a free-air design, allowing for flexible installation options. They come equipped with a dual 4-ohm voice coil configuration, enabling easy system integration and improved power handling. The high excursion capabilities of both models allow for greater cone movement, which translates to richer bass without distortion.

In summary, JL Audio’s 8W3 and 10W3 subwoofers exemplify innovation in car audio technology. Their robust construction, advanced motor design, and flexible installation options make them outstanding choices for audio enthusiasts looking to enhance their sound systems. Whether you opt for the compact 8W3 or the more powerful 10W3, both models promise to deliver a bass experience that elevates your listening experience to new heights.
