Enclosure Specifications

Net volumes given below do not include the air volume displaced by the speaker (Driver Displacement). This value must be added to the net volume along with the displacement of any braces and/or ports (if applicable) to arrive at a gross internal volume. Air inside a port is not part of the effective net volume. Calculate ports as solid, not hollow objects.

The dimensions given for the enclosure examples below take all applicable displacements into consideration.

SAFETY NOTICE!

It is absolutely essential that the completed subwoofer enclosure is mounted firmly to the vehicle with heavy steel bolts (1/2 inch diameter) and large steel washers on both sides of the bolts. This will reduce the likelihood of occupant injury in the event of a collision or sudden deceleration.

W7, 13W7D15 specifications

The JL Audio 13W7D15 is a high-performance subwoofer that exemplifies the brand's commitment to providing exceptional audio quality and innovation in the realm of car audio systems. Engineered for drivers who demand deep, powerful bass and unmatched clarity, the 13W7D15 embodies the latest technologies and meticulous craftsmanship that JL Audio is renowned for.

One of the standout features of the 13W7D15 is its massive 13.5-inch diameter cone, constructed from a proprietary blend of materials. This cone delivers both rigidity and lightweight qualities, allowing for fast response times while producing lower frequencies. The distinctive design of the cone is complemented by the patented W-Cone technology, which enhances the overall surface area without increasing the size of the enclosure. This innovative approach maximizes the output of the subwoofer while ensuring optimal sound quality.

The 13W7D15 incorporates a high-temperature voice coil, designed to withstand extreme heat generated during high-performance audio playback. This feature not only enhances reliability but also contributes to the overall efficiency of the subwoofer, ensuring that it can handle substantial power without distortion. Additionally, the subwoofer utilizes a dual 3-ohm voice coil configuration, providing flexibility in wiring options and enabling users to customize their sound system according to their preferences.

Advanced cooling technology is another significant aspect of the 13W7D15 design. The subwoofer is equipped with a unique cooling system that includes an intelligently designed vent that directs air through the voice coil, effectively dissipating heat. This feature not only extends the longevity of the subwoofer but also maintains consistent performance even during prolonged periods of heavy use.

In terms of power handling, the 13W7D15 impressively manages up to 1000 watts of RMS power with a peak power handling capacity that goes even higher. This robust power handling ensures that the subwoofer can reproduce the most demanding bass tracks with authority, bringing an immersive auditory experience to the listener.

Constructed with attention to detail, the subwoofer features an advanced mounting system, including a durable rubber surround, ensuring that it can handle the vibrations without compromising sound integrity. The robust cast aluminum frame enhances durability while providing a stable foundation for the driver.

In summary, the JL Audio 13W7D15 is a testament to engineering excellence and high-fidelity sound reproduction. With its cutting-edge technologies, impressive power handling, and meticulous design, it stands out as a top choice for audiophiles who seek to elevate their sound experience in both car audio systems and home theater environments.
