WHAT YOU'LL LOVE
CLASS-D DESIGN
The amplifier utilizes an advanced Class-D design to extract the most from the long-excursion driver platform. This design features a tightly regulated switching power supply, allowing the amplifier to generate a remarkable amount of unclipped output voltage.
ADVANCED SIGNAL PROCESSING
Low-pass signals are precisely filtered, thanks to the onboard crossover's 24-decibel/octave Linkwitz-Riley alignment. Phase and polarity controls are on board for the optimal acoustic transition between the subwoofer(s) and main speakers. Flexible input options can accept either line-level or speaker-level signals.
CAREFULLY CRAFTED
To contain the immense pressures created by the Dominion driver, each beautiful cabinet is carefully engineered and constructed by using solid, CNC-cut MDF material with extensive internal bracing and advanced assembly techniques.
PRECISION-BUILT DRIVER
These compact drivers feature massive cast-alloy frames and several unique JL Audio technologies to deliver premium audio quality.
DIRECT CONNECT TO JLINK™ SYSTEM
This subwoofer is compatible with the wireless JLink connection system and has a direct connection port for the JLink receiver.
DOMINION TECHNOLOGIES
DMA-OPTIMIZED WOOFER
Proprietary motor, suspension and cone modeling systems are used to achieve long, linear excursion capabilities with low distortion and powerful sound output.
VENTED REINFORCEMENT COLLAR (VRC™)
The VRC collar design from JL Audio improves the rigidity and stability of the cone/spider/voice coil junction and directs airflow over the voice coil windings for improved thermal performance.
FCAM™ TECHNOLOGY
This “floating cone attach method” of bonding the surround/cone assembly to the voice coil former/spider structure 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.
