The 6 things you want most in a subwoofer

1) Tight, fast resonance free bass. JL Audio's sealed design loads the driver against a cushion of air, and allows it to start and stop on  a dime. You will hear proper impact on movie affects, and musical percussion instruments. 

2) Extended lows. JL Audio is designed to have an even bass response, bringing visceral, body moving bass into your room - enough to put you on a magical air pressure carpet ride

3) Stereo amplifier speaker level connections. Use your Receiver's dedicated RCA subwoofer output (if you have one), or the optional speaker level input that allows you to run cables from any stereo amplifier's speaker terminals directly. Some say the speaker level hook-up provides good coherence with  the main speakers.

4) Purpose Built Driver.  A thing of beauty

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.

5) Effortless Power

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.

5) Go wireless  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.

6) Built like a rock 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.

"If you are looking for the last missing piece for your system -- the sense of lifelike weight and scale -- and don't want to break the bank, I can’t possibly recommend the JL Audio Dominion subwoofer series highly enough."
