Paradigm Defiance X12 12" powered subwoofer

High performance bass to elevate your listening experience Paradigm brings a no-compromise approach to audio, and that approach led them to create their mighty Defiance-X subwoofer lineup. The Defiance X12 gives your home system a clean bass foundation with a low noise floor, using a hefty 12" woofer with a powerful magnet. It's also app controllable, and it includes an advanced self-calibration system for tuning the bass to your room. A scientifically optimized driver and surround Paradigm's pursuit of ultimate sound is deeply rooted in research. In studying how woofer cones and surrounds interact, [t]hey 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(tm)) surround was born. The Defiance X12 uses a lightweight, high-rigidity carbon-loaded polypropylene cone plus the ART surround. The bass remains tight and well-timed, accentuating all the low-end nuances your music and movies might have with ease. This sub boasts surprisingly low bass extension down to 20 Hz, so even if there's a deep, rumbling explosion or a room-shaking kick drum sample playing, the X12 can hit it deeply and with authority.

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(tm)) app. Running Anthem Room Correction is an easy way to get bass that's perfectly tailored to your room and furnishings. The app lets you use your smartphone's mic or the included cali
