Get to know this product.

The XTR-20BPs are yet another astonishing breakthrough for Definitive Technology. The XTR-20BP matches the distinctive XTR series look—a gorgeous hand-polished, aircraft grade Aluminum enclosure. Because they use the same active drivers and tweeter as the rest of the XTR series they're perfect for use as surround speakers in a system made up of larger XTR main speakers.

Superior Performance Components
  • Each Mythos® XTR-20BP contains two 3-1/2 inch XTDD mid/bass drivers that are angled in opposite directions to broaden the midrange dispersion for the kind of diffuse soundfield sought after by home theater enthusiasts for surround loudspeakers. Use the XTR-20BPs for surround channel duties and you'll be rewarded with spacious and enveloping surround effects that will make you feel like you're in the cast of the movie.
Rock-Solid Enclosure
  • Mythos Series enclosures are hand-polished gloss Black aircraft-grade extruded aluminum with proprietary damping technologies that ensure total rigidity. All components are mounted on a resonance-free PolyStone baffle. These rock-solid construction technologies along with state-of-the-art drivers and tweeter serve to deliver classic Definitive Technology sound quality: wide soundstage, spacious imaging, high dynamic impact, and superb realism
