This Subwoofer has been called the "best damn 8-inch subwoofer ever made" for its remarkable performance capabilities and design attributes.

JL Audio® 8" Subwoofer Driver

10th Anniversary Edition - W7 8-inch Subwoofer (500 W, 3 O)

This Subwoofer has been called the "best damn 8-inch subwoofer ever made" for its remarkable performance capabilities and design attributes. An impressive linear excursion envelope that exceeds 0.75 in. (19 mm) one-way allows it to deliver impact well beyond the range of other 8-inch Subwoofers.

The 8W7AE is best used with amplifier power in the 200W - 500W range and is optimized to operate in a 0.875 cu. ft. (24.8 l) sealed enclosure, or a 1.0 cu. ft. (28.3 l) ported enclosure. Detailed enclosure recommendations can be found in the "Specifications" tab.

W7AE (Anniversary Edition) Subwoofers celebrate the 10th Anniversary of the launch of the W7 subwoofers. Functionally, they are identical to the original W7's, but are they distinguished by the following cosmetic differences:

Sensitivity:

With MicroSub+™ systems, the power is built right into the subwoofer system. Housing a proprietary Class D amplifier, this incredible subwoofer system utilizes our exclusive DCD™ amplifier technology to extract maximum output from its specially engineered

JL Audio® Single 8W3v3 MicroSub+™ Subwoofer System

By combining direct power conversion with an ultra-high current output section, DCD™ amplifiers are free of conventional switching power supplies, enabling them to generate remarkable power with unprecedented efficiency.

Key to the enclosure’s performance is its efficient slot-ported design and precise tuning of its 8Wv3 subwoofer driver. Extensive interior bracing permits the use of thinner wall material that maximizes the enclosure's internal volume relative to its exterior volume. The port wraps around two walls of the enclosure to produce the necessary low tuning frequency that ensures excellent extension and response smoothness. The flared port entry and exit further enhance sound quality by minimizing air-flow noises through the port.

Integration to OEM and aftermarket head units is a snap thanks to a variety of input options and automatic turn-on capability (via signal sensing or DC offset sensing). Also included is a variable frequency low-pass filter (50-200 Hz), along with output polarity control switch. Adding an optional RBC-1 remote level control (sold separately) lets you control subwoofer levels directly from the driver’s seat. A quick-disconnect power connector makes it easy to remove the subwoofer when you need the extra space. As with all MicroSub™ systems, these amplified versions produce the kind of output and extension normally associated with much larger systems.

Note: DCD™ amplified systems use very specific components. Never use a DCD™ amplifier or its companion subwoofer(s) with incompatible, non-DCD™ products. Doing so will void the warranty and may cause severe damage.

Finish: Black, high-grade automotive carpet with silver "JL AUDIO" embroidery on front baffle. A steel mesh grille is included to protect the subwoofer driver.

JL Audio® Dual 8W3v3 MicroSub+™ Subwoofer System

Key to the enclosure’s performance is its efficient slot-ported design and precise tuning of its dual 8Wv3 subwoofer drivers, each in its separate airspace. Extensive interior bracing permits the use of thinner wall material that maximizes the enclosure's internal volume relative to its exterior volume. The port for each driver wraps around two walls of the enclosure to produce the necessary low tuning frequency that ensures excellent extension and response smoothness. The two flared port entries/exits, one on each end of the enclosure, further enhance sound quality by minimizing air-flow noises through each port.

HVT stands for Horizontal Vertical Transforming technology which transforms horizontal movement into vertical movement of a woofer diaphragm to produce true, powerful and wide-range bass.

Pioneer 8.25" HVT Sealed Active Subwoofer

Proprietary New Speaker Design Technology

The TS-WH500A amplified subwoofer system is a truly groundbreaking approach in loudspeaker design. HVT technology uses a unique linkage mechanism, which allows the magnet and voice coil of the dual motor structure to be positioned horizontally to the left and the right side of vertically moving dual speaker diaphragms. Combined, the two diaphragms have an effective surface area equal to a conventional 8" subwoofer and fire in a bipolar arrangement, increasing output while also canceling destructive vibrations within the enclosure. The result of this innovative technology is a subwoofer system with significantly reduced physical depth, while maintaining greater excursion and linearity for superior bass reproduction, natural sound quality and higher output.

The result of this innovative technology is a uniquely compact speaker with the most compact enclosure in the industry that combines woofer surface area equal to most other compact active subwoofer systems with greater maximum excursion for superior performance and sound quality. The HVT subwoofer will fit easily in a wide range of vehicle applications (compact and subcompact vehicles, hybrid vehicles, trucks and SUVs, etc.) without sacrificing performance or sound quality.

Compared to a traditional subwoofer, the TS-WH500A produces less vibration and less noise. The subwoofer offers wider low range frequency reproduction for well-balanced bass from various musical instruments. The voice coil and diaphragm work in symmetry to cancel unnecessary vibrations and reduce noise which instead would travel through the vehicle’s body.
