  • Product Description

    Born from JL Audio’s vast collection of advanced technologies, Dominion 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 compact applications.

    Purpose-built to reproduce powerful low-frequency events with stunning impact and precision, the Dominion 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, Dominion subwoofers are capable of peak-to-peak excursions well in excess of 2.5-inches (63 mm - d108), and 2.7 inches (68 mm – d110), without distress or audible distortion.

    Dominion amplifiers utilize an advanced Class D design in order to extract the most from the long-excursion driver platform. 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 powered subwoofers remain in their comfort zone, which is well beyond the point where most small subwoofers run out of power or driver capability.

    With a host of signal processing features included, Dominion powered subwoofers can be integrated into most systems with ease. Low-pass signals are precisely guided, thanks to the onboard crossover’s 24 dB/octave Linkwitz-Riley alignment. Phase and polarity controls are onboard to aid in achieving the optimal acoustic transition between the subwoofer(s) and main speakers. Flexible input options are on-hand to accept either line-level or speaker-level signals. Connect a JLINK TRX system (sold separately) to the onboard Wireless Link port and enjoy the freedom to position your Dominion almost anywhere, up to 100 feet (30 meters) away from your source unit.

    To contain the immense pressures created by the Dominion driver, each beautiful cabinet is carefully engineered and constructed using solid, CNC-cut, MDF material with extensive internal bracing and advanced assembly techniques. All Dominion powered subwoofers are built with pride and precision in JL Audio’s U.S. factory to deliver years of listening enjoyment.

    Dynamic Motor Analysis - DMA Optimized Motor
    JL Audio's proprietary Dynamic Motor Analysis system is a powerful suite of FEA-based modeling systems, first developed by JL Audio in 1997 and refined over the years to scientifically address the issue of speaker motor linearity. This leads to vastly reduced distortion and faithfully reproduced transients... or put simply: tight, clean, articulate bass.

    Vented Reinforcement Collar
    JL Audio's Vented Reinforcement Collar (VRC®) improves the rigidity and stability of the cone/spider/voice coil junction and directs airflow over the voice coil windings for improved thermal performance.

    Floating Cone Attach Method - FCAM™
    This assembly technique, conceived by JL Audio, ensures proper surround geometry in the assembled speaker for better excursion control and dynamic voice coil alignment.

    Engineered Lead-Wire System
    Carefully engineered lead-wire design and attachments ensure controlled, quiet lead-wire behavior under the most extreme excursion demands.
