Driver Technology

Spatial Array: 

  • The Definitive Technology Mythos SSA-42 incorporates Spatial Array, a unique patented technology that optimizes the spatial presentation of five-channels to create the illusion that you are surrounded by five separate high-performance speakers.
  • Spatial Array Surround technology uses subtle, but complex directional cues to completely free the sound from the speaker enclosure and convince your ear/brain listening mechanism that you are surrounded multiple speakers.
  • Since Spatial Array technology does not depend on bouncing sound off walls, it works in virtually any room and set-up configuration.
  • The SSA-42 uses Spatial Array technology on the front left and right speakers as well as the surround channels, so that you get big three-dimensional imaging from both stereo and multi-channel sources.

BDSS Driver Technology: 

  • The Front left, Front right, and Center channel drivers of the SSA-42 utilize Definitive's exclusive and patent-pending Balanced Dual Surround System (BDSS) technology.
  • Speaker cones usually have one support point at the circumference of the cone (called the surround), but BDSS drivers have two support points or surrounds.
  • This design suppresses cone resonance and promotes a longer, more linear cone motion for higher output, lower distortion and more accurate frequency response.
  • As a result you will enjoy perfectly natural and lifelike timbre with crystalline clarity on voices, musical instruments ,and movie sound effects, even at high-volume levels.

Pure Aluminum Dome Tweeter: 

  • The Definitive Technology SSA-42's tweeter is a pure aluminum dome, which has been heat-treated to relax the crystal structure and then coated with a ceramic to produce extended highs.
  • In order to keep the enclosure from being longer than popular sized video displays, Definitive engineers positioned the front channel tweeters in front of the drivers.
  • While this is a commonly used space-saving technique, a tweeter placed in front of the driver usually interferes with the driver's sound waves.
  • Using computer and physical modeling, Definitive engineers developed unique tweeter-housing geometry and venting that eliminates interference effects for audiophile-grade clarity, precision, and accuracy.


  • The Definitive Technology Solo Surround Array 42 features three 3-1/4" BDSS drivers with axially-aligned 3/4" pure aluminum dome tweeters; two 3-1/4" BDSS high-output full-range drivers, and four 3" full-range high-output surround drivers.

Break-In Period: 

  • The Mythos SSA-42 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 SSA-42's enclosure is fabricated from aircraft-grade, hand-polished gloss black extruded aluminum, styled to perfectly match today's flat panel plasma and LCD TVs.
  • Internal baffles and braces inside the enclosure eliminate interference effects between drivers and channels for true audiophile purity and maximum channel separation.


5-Way Binding Posts: 

  • The SSA-42  is equipped with 5 pairs (Front left, Front right, Center, Rear right, Rear left) of gold-plated, 5-way binding posts to attach your 5.1-channel home theater receiver's speaker wire.

Mounting Options


  • The Mythos Solo Surround Array 42 is designed for horizontal use only. The 5-channel loudspeaker can be positioned below or above your flat-panel television.
  • The SSA-42 matches perfectly with 42-inch and larger flat-panel televisions.


  • The Definitive Technology SSA-42 comes with easy-to-install mounting hardware that allow it to mount on the wall above or below your television.
  • The Mythos SSA-42 comes with a wall mount bracket that allows direct mounting to a wall.
  • The SSA-42 can also be mounted directly to select flat-panel TV swing out arm-style wall mounts, so that the speaker angle changes with the TV angle.
  • It also includes hardware that allows you to place the speaker on the TV, on a shelf , or on a table-top (surface must be at least 5-inches deep).

Angle Adjustment: 

  • The Mythos Solo Surround Array 42 comes with two brackets and two feet which screw into the speaker's wall-mount 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 these feet.
  • By varying how far you screw in-and-out the feet, 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.
