Enjoy rich sound from this sleek, on-wall speaker

Definitive Technology's Mythos Ten is the best on-wall model in their Mythos lineup. It uses many of the same technologies found in Definitive's Mythos floor-standing speakers to provide a wide soundstage, pinpoint imaging, and superb realism in a slim, wall-mountable speaker cabinet. This versatile speaker can be used as a left, right, or center channel speaker in a home theater setup, and it's designed to match 50" or larger flat-panel TVs.

Grille off shot

High-tech drivers for exceptionally detailed sound


At the center of the cabinet are two 5-1/4" midrange drivers surrounding a 1" dome tweeter. Definitive's Balanced Dual Surround System (BDSS) driver technology helps increase the tiny speakers' output without increasing the size of the enclosure. The pure aluminum dome tweeter produces extended highs that reveal nuance and shimmer without a trace of edginess. Flanking the midranges are two 5" x 8" racetrack-shaped low bass radiators, which give the Mythos Ten better bass performance than you might expect from a slim, on-wall speaker. Die-cast aluminum baskets, a resonance-free PolyStone baffle, and proprietary damping technologies built into the cabinet ensure clean sound.

Gorgeous aircraft-grade aluminum cabinet

The enclosure is made of black hand-polished aluminum for a sleek look that'll go well with most modern décors. The Mythos Ten comes with a wall-mounting bracket that will adapt to most swing out, arm-style TV wall mounts, so the speaker moves along with your TV when you reposition it.

Building a system

Put together a complete home theater system using Mythos Tens for your front three channels. Add on Definitive's Mythos Gem XL surround speakers for wraparound sound and SuperCube II subwoofer for high-impact bass. The Mythos Ten also makes a great center channel complement to Definitive's powerful Mythos ST SuperTower floor-standing speakers.

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.

Product Research

Overview: The Definitive Technology Mythos Ten loudspeaker offers maximum versatility for your home theater and flat-panel entertainment system; it can be used as an on-wall Front, Center, or Surround speaker, or as a shelf-mounted center speaker. The Mythos Ten features a high-gloss aircraft-grade extruded aluminum enclosure with proprietary damping technologies to ensure total rigidity and perfectly accurate sound. It also features two high-definition BDSS 5-1/4 inch drivers pressure-coupled to two 5 x 8 inch (racetrack-shaped) planar low-bass radiators for a total bass radiating surface greater than a that of a 12 inch woofer , and a 1 inch (25mm) ceramic-coated pure aluminum dome tweeter with an acoustically contoured faceplate for excellent high frequency extension, detail and smoothness.

Driver Technology

Speaker Array: Each Mythos Ten contains a D'Appolito array consisting of two high-definition 5-1/4 inch drivers that are pressure-coupled to two 5 x 8 inch (racetrack-shaped) planar low-bass radiators for a total bass radiating surface greater than that of a 12 inch conventional woofer, surrounding a 1-inch dome tweeter housed in an acoustically isolated sealed enclosure.  The driver baskets are die cast aluminum. The bass roll-off of the Mythos Ten is smooth and controlled, allowing it to seamlessly blend with a powered subwoofer, such as Definitive's SuperCubes, for audiophile-grade home theater performance. The tweeter's dome is heat-treated to relax the crystal structure and then coated with a ceramic to produce extended highs.

BDSS Technology: The Mythos Ten drivers feature Definitive's patent-pending Balanced Double Surround System (BDSS) technology that supports the speaker cone at both the inner and outer edges for longer, more linear excursion, greater clarity and finely textured inner detail. Definitive Technology's Balanced Double Surround System (BDSS) driver offers a wide-bandwidth accurate frequency response, broad dispersion, low distortion, and detail retrieval; so you hear more the music with greater accuracy and enjoyment. BDSS drivers incorporate the following design features.

  • Balanced Double Surrounds: The speaker's balanced double surrounds support the cone at two points to provide better mechanical stability for longer, more linear excursion, and improved damping to suppress parasitic cone resonance.
  • Mineral-Filled Polymer Cone: The loudspeaker features a deeply drawn mineral-filled polymer cone engineered using sophisticated 3D modeling techniques for wide range performance.
  • Waveguide: The cone's integrated waveguide smoothes off-axis response for broad, even dispersion and better imaging.
  • High Temperature Voice Coil: The driver's high temperature, oversized, lightweight vented voice coil offers improved power handling and quick transient response. The voice coil is also lengthened to increase linearity and lower distortion.
  • Magnet Structure: The driver's magnetic system is optimized by finite element analysis to maximize magnetic flux in the gap for high efficiency and linear excursion.
  • Die-Cast Alloy Basket: The die-cast alloy basket minimizes ringing and vibration while the open area minimizes back wave reflection.

Break-In Period: The Mythos Ten 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 Ten enclosure is 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 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.


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

Mounting Options

Applications: The Mythos Ten can be used as left & right main, center, and surround speakers in your home theater audio system. The Mythos Ten can be mounted on the wall vertically or horizontally as a left & right main speaker or surround speaker. The Mythos Ten can also be use as a center channel speaker and wall-mounted horizontally or placed horizontally on a table-top or shelf.

Mounting: The Mythos Ten comes with easy-to-install mounting hardware that allows you to hang the speaker on the wall below, above, or beside your flat-panel television in a vertical or horizontal orientation. The Mythos Ten is engineered to be placed flush with the wall and close to the edge of your television while delivering realistic sound that is accurate, with lifelike imaging and clarity. The Mythos Ten's wall mount bracket allows direct mounting to a wall and also adapts to flat-panel TV swing out arm-style wall-mounts so that the speaker angle changes with the TV angle. A supplied adjustable foot and two self-adhesive rubber feet permit easy shelf mounting when the speaker is used in the horizontal center-channel format.

Angle Adjustment: The Mythos Ten has a bracket with foot which screws into the speaker's wall-bracket to stabilize the speaker and allows you to adjust the vertical angle when the system is placed on a flat horizontal surface. When you set the speaker down, the speaker will lean back and rest on this foot. By varying how far you screw in-and-out the foot, you can adjust the vertical angle of the speaker. It is recommended that you aim the center-speaker so that it aims directly towards the height of the listeners' ears.

Crutchfield Customer Review (What's this?)

The Mythos Ten is major improvement over the old Polk Center Channel Speaker that it replaced. It blends in well and is solid. Dialogue is clear and crisp. Even my wife approves!

Crutchfield Customer Review (What's this?)

I'll apologize in advance for not being expansively audio-phile in my review. I'm running this speaker through a Marantz 7005 in association with 2 Mythos St speakers and a new Panasonic 65 inch plasma. The sound is clear and precise. Understand, it was replacing the speakers that came with an analog set at least 10 years old that were not being run through any amplifier. So in essence, it would be tough NOT to be much better than what i had.

Pros: Crisp highs with very good conversational projection

Cons: none

Awesome center channel speaker

Pros: Sounds great

Cons: None

Mythos 10

Written By Blayne C., Charleston, SC on Sunday, January 22, 2012

Crutchfield Customer Review (What's this?)

Excellent! This speaker has a presence and clarity that is leaps and bounds above the old JBL center I had been using. I have a pair of B&W 803s that I use as fronts sometimes and the Mythos 10, although not quite in the same league, holds its own well as the center when used in the home theater configuration. You will want to match it with a good subwoofer in order to round out the bottom of the spectrum but the result is extremely rewarding. Center is definately where it should be now. Voices are crystal clear and all dialogs come thru without being forward. Overall midrange is very smooth with no brassiness and the upper registers are clean and extended without any enhanced 'sizzle'. Overall great audio balance. Efficient.

Pros: Clarity, efficiency.

Cons: None noted

Crutchfield Customer Review (What's this?)

You have never heard a great center channel speaker until you try the Mythos 10. I was using Klipsch's top of the line and the Mythos 10 blows it away. The voices are significantly clearer!
