Our take on the Definitive Technology Mythos XTR-SSA3

by Marshall Chase
Definitive Technology

Sound bar speakers: room-filling sound with less clutter

Add big sound to your TV without a roomful of speakers. Sound bars require minimal space and wiring, and their sleek designs complement today's flat-panel TVs. Most sound bars have their own built-in amplification, so you won't need to use a home theater receiver. Some models use advanced surround processing and carefully aimed speaker drivers to simulate the effects of a full home theater audio system.

A stylish upgrade to TV sound

Definitive Technology's Mythos XTR-SSA3 gives you serious audio performance in an elegant sound bar design that cuts down on room-clutter. This three-channel speaker connects to your home theater receiver and takes the place of the left-, center-, and right-channel speakers of a traditional surround sound system. Six mid-bass drivers and three 1" tweeters elevate movie and TV dialogue to the forefront, where it belongs. And at just over 1-1/2" deep, the aircraft-grade aluminum enclosure makes an outstanding decorative match for your TV, so your eyes and ears will be equally happy.


Thin never sounded so good

The 'SSA3 uses patented Solo Surround Array (SSA) technology to vastly widen the stereo image to lifelike proportions. For complete surround sound enjoyment, mate the XTR-SSA3 with matching Mythos XTR-20BP surround speakers or any of Definitive's in-wall or in-ceiling speakers. For more bass punch add a powered subwoofer.

Flexible placement

The 'SSA3 speaker comes with everything you need to locate it where you like. It can be wall mounted simply using the rear keyhole slots. Plus the 'SSA3 comes with adjustable shelf support feet so you can place it on your A/V cabinet below your TV.


Got wire?

Most speakers don't include any. Learn about choosing and installing speaker wire at the Crutchfield Learning Center.

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.

XTR-SSA3 Soundbar: The Definitive Technology Mythos XTR-SSA3 Soundbar provides three channels (Front left/Center/Front right) from one ultra-slim loudspeaker. The XTR-SSA3 Soundbar is the perfect audio solution when you are unable or unwilling to use three discrete front speakers in your home theater. The XTR-SSA3 provides dynamic punch, wide frequency range, and broad dispersion. The Soundbar's ultra-slim design is a perfect match for today's ultra-thin flat-panel TVs. It comes with a table-top stand and is wall-mountable.

Note: For complete surround sound enjoyment, mate the XTR-SSA3 with matching Mythos XTR-20BP surround speakers (735XTR20BP, sold separately) or any of Definitive's in-wall or in-ceiling speaker solutions.

Driver Technology

SSA (Solo Surround Array) Technology: The Mythos XTR-SSA3 Soundbar's left & right channel arrays utilize patented SSA technology to vastly widen the stereo image to lifelike proportions. You'll enjoy a sonic image that is as wide as the wall with incredible three-dimensionality.

Pure Aluminum Dome Tweeters: The XTR-SSA3 Soundbar's three 1" hyper-definition aluminum dome tweeters are the same tweeters found in Definitive's award-winning state-of-the-art Mythos ST SuperTower. The pure aluminum dome tweeters provide clarity, dynamic range, and extended high-frequency response.

XTDD Technology Drivers: The Definitive Technology Mythos XTR-SSA3 Soundbar utilizes six 3.5" Definitive XTDD technology anodized Aluminum dome drivers for extraordinary performance. Using state-of-the-art computer modeling and decades of speaker design experience, Definitive engineers eliminated every inch of wasted space, optimized every part, and maximized the moving surface area of a dynamic driver to shrink it down to a very compact dimension without giving up ultra high performance audio fidelity. The XTDD drivers provide dynamic punch, a wide frequency range, and broad dispersion that flat vibrating membrane panel-type speakers simply cannot match.

Enclosure Design

Ultra-Thin Aluminum Enclosure: The Definitive Technology Mythos XTR-SSA3 Soundbar features an ultra-thin aircraft-grade aluminum cabinet that fits today's flat-panel televisions perfectly. By specially shaping the enclosure and incorporating stiffing ribs and channels, Definitive made the space-efficient extruded aluminum enclosure ultra-rigid and resonance-free. The magnets of the XTDD drivers protrude through the rear wall of the enclosure to further minimize depth. A thermally conductive gasket seals the enclosure/magnet interface and transfers heat from the driver's rare-earth magnet to the enclosure, making the whole enclosure a giant heat dissipater.

Magnetic Grille: The Mythos XTR-SSA3 Soundbar features a black cloth magnetic grille which easily attaches and detaches from the speaker.

Connections

Speaker Terminals: The Mythos XTR-SSA3 is equipped with a plug-in C-clamp speaker terminal to attach your receiver's speaker wire (up to 12 AWG).

Color-Coded: The speaker terminals are color-coded and labeled (+/-) to distinguish between Front Left, Center, and Front Right speaker channels.

Mounting Options

Placement: The Mythos XTR-SSA3 is designed for horizontal use only. The Soundbar can be positioned below, above, or in front of your flat-panel television. The XTR-SSA3 matches perfectly with 46" to 65" flat-panel televisions.

Table-Top Mount: For shelf-mounting in front of or below the TV, the XTR-SSA3 comes with two different sets of adjustable feet. For shelf-mounting in front of or below the TV, the XTR-SSA3 comes with clever adjustable feet that can raise the speaker over the TV's protruding shelf stand. It can also be placed on a shelf below the TV and angled up towards your ears via the supplied shelf supports

  • Adjustable Height Feet: Use these adjustable feet when placing the Soundbar on the same shelf as the TV. They allow you to raise the speaker over the TV's pedestal base.
  • Adjustable-Angled Feet: Use these adjustable supports when placing the Soundbar on a shelf below your flat-panel TV. They allow you to angle the speaker up towards ear level.

Note: The adjustable feet attach to the Soundbar speaker using the supplied hardware (1/4"-20 x 12mm screws).

Wall-Mount: The Definitive Technology XTR-SSA3 can be mounted to the wall, above or below your flat-panel television. The Soundbar includes a wall-mount bracket and hardware, along with dual keyhole slots.

  • Wall-Mount Bracket: The Mythos XTR-SSA3 comes with a wall mount bracket that allows direct mounting to a wall (wall-mount screws not supplied). The wall-mount bracket attaches to the Soundbar speaker using the supplied hardware (1/4"-20 x 12mm screws).
  • Dual Keyhole Slots: The XTR-SSA3 Soundbar also features dual rear-panel keyhole slots which allow you to easily hang the speaker on the wall without any bracket by simply using two screws (not supplied). The two keyhole slots are spaced 32.75" apart.

Definitive Quality

Written By Max Power, Champaign, IL on Friday, August 16, 2013
Crutchfield Customer Review (What's this?)
 
Very well made. It looks & feels like a quality product. Sound quality is quite good. And the fact that it's no thicker than my TV is just great.
Pros:
Overall size and thinness of the speaker.
Cons:
Haven't seen any yet.

Great sound bar except for one design flaw.

Written By Art, Pebble Beach, CA on Tuesday, September 25, 2012
Crutchfield Customer Review (What's this?)
 
This sound bar exudes quality. The audio is great, it's truly beautiful, and solidly constructed. I disagree with another reviewer about the logo. IMO, it's fine; not obtrusive at all.

But it has a big design flaw: the connector. There is plenty of room on the back for proper connectors. Instead, this speaker has a single piece that you remove and feed all the speaker wires into. The problem is that the wires (and their bare ends) are WAY too close to each other and the whole thing is just far too compact than necessary. OK, maybe banana plugs would be overkill, but this is not a smart phone that requires ever-smaller components. It's a speaker that's almost 3 feet wide.

Worse still, I am trying to mount this to swivel with the TV. The little connector does not have a positive mechanical lock, so it can too easily just pop out.

Definitive, rethink this connection! If this part had been done right, this speaker would easily be 5 stars.

Excellent product

Written By JayG, Arlington, VA on Monday, February 13, 2012
 
I recently purchased this item along with the Def Tech Mythos 20BP surrounds. I also have a Def Tech Supercube 2000 Sub and a Denon AVR 1912 Reveiver. I have a non-ideal set up as my couch is against the back wall. I mounted the soundbar under my TV on the wall and installed the surrounds near the the ceiling angling down towards the couch. After some tinkering with the different settings on my receiver, I am extremely happy with the sound quality coming from the speakers. The voices are clear, the left and right channel sounds are also clear and expansive, and the surrounds make you feel like you are in the middle of the action. Music sounds very good as well. I highly recommend this soundbar if you are looking to a L/R/C option that is sleek looking and sounds great.
Pros:
Great sound in an attractive looking speaker.
Cons:
None

Beautiful, but some minor annoyances

Written By ggr, Philadelphia, PA on Wednesday, February 01, 2012
Crutchfield Customer Review (What's this?)
 
It's gorgeous, obviously, and the pictures don't actually do it justice. It is NOT a replacement for properly-configured floorstanders, bookshelves or rotating-baffle in-walls. But it IS a fantastic replacement for the tiny, tinny speakers that are probably insider your beautiful flat panel.

Now, for the tough part:

1. Why, why why did they put the whole model number on the front? This is supposed to be a beautiful piece of wall-hanging gorgeousness and it says "Definitive XTR-SSA3" on the front? Why not just "Definitive" like all their other stuff???

2. It came with the wrong mounting plate (ostensibly, the one for it's big brother 5-driver model). Not a huge deal as it hangs perfectly fine using the 2 keyhole slots on the back.
Pros:
Beautiful, except for the label. Nice speaker jack design. Solid, well-built. Sounds great, exactly as should be expected of something this shape and size.
Cons:
The front label is a horrible design aesthetic. Poor quality control (shipped wrong bracket in box).
