Deep impact and musicality from a compact subwoofer
JL Audio powered subs 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'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'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.
To top things off, every d108 powered sub is precision-built in JL Audio's U.S. factory in Miramar, Florida using advanced assembly techniques. Each enclosure is carefully engineered and constructed with solid MDF and extensive internal bracing to give you years of listening enjoyment.
