Features & Specifications



JL Audio Home Audio D108-GLOSS 8″ Powered Subwoofer – #96282

JL Audio Home Audio D108-GLOSS Powered subwoofer have a reputation for delivering fantastic performance with high-end two-channel audio systems and home theater setups alike. Judging by all of the five-star reviews they receive on our website, our customers completely agree. With the Dominion d108, JL has managed to fit that winning combination into a compact enclosure that takes up less than a square foot of floor space.

Long-excursion driver and serious power pumps out heavy bass

The D108-GLOSS’s excellent performance starts with its beefy 8″ driver. This woofer’s extremely long, peak-to-peak excursions — well in excess of 2-1/2″ — can displace a large amount of air to produce the deepest bass. JL Audio uses sophisticated DMA (Dynamic Motor Analysis) technology which lets them shape, control and stabilize the driver’s magnetic field strength to ensure ultra-linear motor force throughout its long excursion range. This allows the woofer to more faithfully track the input signal for greater bass definition and dynamics.

It also takes a special amp to power the D108-GLOSS’s driver. Fortunately, the 500-watt powerhouse JL employs is more than up to the task. This advanced Class D amplifier uses a tightly regulated switching power supply to provide enormous amounts of unclipped voltage. This design approach allows the amplifier to be more compact, lightweight, and efficient, yet still deliver abundant low-distortion power to extract peak performance from the sub’s driver.

Dominion Series Powered Sub

JL Audio’s Dominion series D108-GLOSS powered subwoofers combine a state-of-the-art subwoofer driver and an advanced Class D amplifier to deliver unmatched performance and value for a wide variety of music and movie applications.

8″ Long-Excursion Woofer

The JL Audio Dominion series D108-GLOSS sub houses an 8″ long-excursion woofer. The woofer has been purpose-built to reproduce powerful low-frequencies with stunning impact and precision. The 8″ driver employs JL Audio’s exclusive DMA (Dynamic Motor Analysis) technology to produce higher output levels with reduced distortion, as well as improved dynamic tracking and resolution. As a result, the 8″ woofer is capable of peak-to-peak excursions well in excess of 2.5″ (63mm), without distress or audible distortion.

500W Class D Amplifier

The JL Audio D108-GLOSS powered subwoofer employs an advanced 500W Class D amplifier in order to extract the most from the long-excursion 8″ driver. This design features a tightly regulated switching power supply, allowing the amplifier to generate prodigious amounts of unclipped output voltages. These technologies ensure that the Dominion series powered sub remains in its comfort zone, which is well beyond the point where most small subwoofers run out of power or driver capability.

Sealed MDF Cabinet

To contain the immense pressures created by the powered sub’s 8″ long-excursion driver, the beautifully crafted cabinet is carefully engineered and constructed using solid, CNC-cut, MDF material with extensive internal bracing and advanced assembly techniques. The cabinet utilizes an acoustic suspension (sealed) design for tight, accurate, natural sound bass.


The JL Audio D108-GLOSS powered subwoofer provides a variety of controls to fine-tune the sub to your room application and source content. The controls are found on the rear-panel of the powered sub.
