Compact, versatile speakers deliver rich sound

Enjoy detailed sound from Definitive Technology's most compact multi-purpose speakers — the Mythos Gems. Each speaker houses two 3-1/2" mid/bass drivers that are angled away from each other to create a spacious, lifelike soundstage. They flank a 1" pure aluminum dome tweeter that reveals lots of detail and nuance without adding a trace of edginess.

Slim profile makes it easy to place in your room

The enclosure is made of black hand-polished aluminum for a sleek look that'll go well with most modern décors. A keyhole slot on the back of each speaker allows you to mount them on your walls for out-of-the-way placement, or you can place them on Definitive's matching GemStands. The Gems are voice-matched with the complete Mythos series, so they're perfect for use as compact surround speakers in a system made up of larger Mythos main speakers. Or create a complete Gem home theater system using the Mythos Seven center channel speaker and either the SuperCube 2000 or ProSub 800 subwoofer.

Did you know?
Your new speakers will probably sound better after several weeks of use than they do right out of the box. That's because the material surrounding the woofers will loosen up, allowing the drivers to move more fully. Definitive Technology estimates a break-in period of 24 to 48 hours of playback before the speakers will deliver optimum sound quality. For more information and helpful tips, check out this article from Definitive's website about conditioning your speakers.

Driver Technology

Angled Drivers: Each Mythos Gem contains two 3-1/2 inch long-throw mid/bass drivers that are angled in opposite directions to broaden the midrange dispersion. The bass roll-off of the Mythos Gem is smooth and controlled, allowing it to seamlessly blend with a powered subwoofer, such as Definitive's SuperCubes, for audiophile-grade home theater performance.

Pure Aluminum Dome Tweeter: EachMythos Gem is equipped with a 1-inch ferrofluid-dampened pure aluminum dome tweeter for extended, smooth highs.

Linkwitz-Riley Crossover Network: The Mythos Gem uses a sophisticated Linkwitz-Riley Crossover Network to perfectly blend the drivers into a sonically seamless audio environment.

Break-In Period: The Mythos Gem will sound good right out of the box; however, an extended break-in period of 20-40 hours or more of playing is required to reach full performance capability. The break-in period allows the suspensions to work in and results in full bass, a more open midrange, and smoother high frequency reproduction.

Enclosure Design

Extruded Aluminum Enclosure: The Mythos Gem enclosure is hand-polished gloss back aircraft-grade extruded aluminum with proprietary damping technologies that ensure total rigidity. All components are mounted on a resonance-free PolyStone baffle. These construction technologies along with state-of-the-art drivers and tweeter serve to deliver high quality sound with a wide soundstage, pinpoint imaging, high dynamic impact, and superb realism.

Connections

Binding Posts: Each Mythos Gem is equipped with a pair of gold-plated, 5-way binding posts to attach your receiver's speaker wire.

Mounting Options

Mounting: The Mythos Gem comes with a wall-mount bracket, so you can easily mount the speaker on the wall (mounting screws not included). The Mythos Gem also features a 1/4"-20 threaded insert for using Definitive Technology's optional articulating wall-bracket (ProMount 80) to mount the speaker on the wall. In addition, the Mythos Gem can be placed on a table-top, shelf, or stand.

Crutchfield Customer Review (What's this?)

Crutchfield was great they processed my order and shipped my purchases
quickly and accurately. Wonderful company.

I purchased two sets of the Mythos Gems one set for surround and one set for
rear speakers, I have a set of Mythos 2 for front, Mythos 3 for center and super
cube III for sub. To be fair my previous systems was (4) infinity reference 71
MKII with Infinity center and Infinity 500w, 15" sub. The new system has
substantially less base for listening to music but it rocks for movies. The clarity
with the new system is amazing. I haven't had much time to play with the
system yet, I miss the base hence the 4 stars. I am hopeful that once I get
everything tuned and figure out the settings for the new system the base will be
better. Overall very impressed with the new speakers.

P.S. previous receiver was a Denon AVR4802, new receiver is a Onkyo TX-
NR3008.
