Greatness in Compact Form
The Mythos Gem XL is the bigger, beefier big brother of the Mythos Gem. The Gem XLs make the distinctive Mythos look — a gorgeous hand-polished, aircraft grade Aluminum enclosure - available in superbly designed high performance compact loudspeakers. Because they are voice-matched with the complete Mythos Series, they're perfect for use as compact, convenient surround speakers in a system made up of larger Mythos main speakers, or as a complete Gem XL-only compact high performance home theater system when combined with a Mythos Three Center Channel Speaker and a SuperCube subwoofer.

Mythos Gem XL Speakers feature an easy-to-use keyhole slot for simple wall mounting that looks amazing next to your wall mounted flat screen television. You can also use popular articulating wall mount brackets (available separately).

State-of-the-art engineering technology delivers the classic level of Definitive Technology sound quality: wide, dynamic soundstage, pinpoint imaging, and superb realism. Packed into these compact enclosures are proprietary damping technologies that ensure total rigidity, angled mid/bass drivers in PolyStone baffles, and sophisticated Linkwitz-Riley Crossover Networks to more perfectly blend the drivers into a sonically seamless audio environment. Nothing complements your high definition flat screen television with more style, versatility and sheer performance than the beautiful Mythos Series models.

Superior Performance Components
Each Mythos® Gem XL contains two 4-1/2 inch 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 fanatics for surround loudspeakers. Use the Mythos Gem XLs for front and 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. The bass roll-off of the Mythos Gem XL is smooth and controlled, allowing it to seamlessly blend with a powered subwoofer, such as Definitive's SuperCubes, for audiophile-grade home theater power and precision.

The array's 1 inch Pure Aluminum dome tweeter produces extended highs that reveal nuance and shimmer without a trace of edginess.

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, pinpoint imaging, high dynamic impact, and superb realism.
