Paradigm Defiance X15 15 powered subwoofer with mobile app control and room correction mic

About the Paradigm Defiance X15

Top-tier performance from Paradigm

The Defiance X15 subwoofer is one of Paradigm’s biggest and loudest.  It’s a no-holds-barred heavyweight that was built to give your home system superior bass. This 92-pound sub features a 15-inch woofer powered by a built-in 900-watt amp to deliver room-shaking, perfectly balanced bass for just about any size of room. It’s also app-controllable, letting you make adjustments on the fly with your phone or tablet. Better yet, it can also tune its sound to your room using the included calibrated mic, ensuring you’re getting the best sound possible.

What creates the thunder?

Paradigm’s pursuit of ultimate sound is deeply rooted in research. In studying how woofer cones and surrounds interact, they found that the spot where the two meet can cause some unwanted distortion, particularly at high excursion points. Paradigm found that by “overmolding” the woofer cone to the surround, they could drastically reduce distortion, while at the same time increasing the output of the subwoofer. Thus, their Active Ridge Technology (ART™) surround was born.

The Defiance X15 uses a lightweight, high-rigidity carbon-loaded polypropylene cone plus the ART surround. The bass remains tight and punctual, accentuating all the low-end nuances your music and movies might have with ease. It boasts solid low-frequency extension down to 18 Hz, so even if there’s a deep, rumbling explosion or a room-shaking kick drum sample playing, the X15 can hit it deeply and with authority.

Easy control and room correction

Through the Paradigm Subwoofer Control App (free for iOS® and Android™) you’ll be able to adjust the sub’s volume, low-pass filter, phase, more without having to mess with the controls on the back. The app includes three listening preset modes, Music, Movie, and Night, for dialing in the right bass for the occasion. It also has a nifty shortcut to the Anthem Room Correction (ARC™) app.

Running Anthem Room Correction is an easy way to get bass that’s perfectly tailored to your room and furnishings. It works by playing a few test tones and measuring sound reflections in your listening space. Then it compares the results to lab standards and adjusts the sound accordingly by using a proprietary DSP algorithm. The final product is naturally blended, accurate bass.

If you have an iOS® device, you can use your phone’s built-in microphone to handle the calibration. However, if you use an Android device, you’ll need to use the included Anthem Room Correction microphone. For the best results in either case, using the calibration mic lets you use the latest, most powerful iteration of the ARC software on your computer.

No more cables

Cables can be an additional hassle when you’re getting your subwoofer set up in just the right position. Luckily, Paradigm’s Defiance WT wireless subwoofer kit (sold separately) lets you cut the cord. Just plug the transmitter into your receiver or amp and insert the kit’s wireless receiver module into the custom-designed port on the back of the subwoofer. The transmitter can send a signal to the subwoofer from up to 50 feet away.

Partnered with Canada’s National Research Center

Paradigm is partnered with Canada’s largest federal research and development organization, the National Research Center (NRC). The two research the nature of sound and human hearing together, and their findings influence the design and performance of Paradigm’s loudspeakers and subwoofers. The result is a uniquely realistic sound that’s backed by ample scientific research.
