Stylish, flat-panel friendly center speaker

Get top-notch center channel sound from Definitive's wall-mountable, high-performance Mythos Three. It uses many of the same technologies found in Definitive's Mythos floor-standing speakers to provide a wide soundstage with pinpoint imaging, crystal-clear dialogue, and superb realism. And at just under 4-1/2" deep, this center channel speaker looks right at home below today's slim TVs.

High-tech drivers for exceptionally detailed sound


Close-up of the pure aluminum dome tweeter.

At the center of the cabinet are two 4-1/2" midrange drivers surrounding a 1" dome tweeter. The pure aluminum dome tweeter produces extended highs that reveal nuance and shimmer without a trace of edginess. Flanking the midranges are two 4-1/2" bass radiators, which give the Mythos Three better bass performance than you might expect from such a slim 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 Three 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. And a rubber-tipped adjustable foot on the bottom of the cabinet allows you to aim the speaker upwards towards your listening position when placed on a low shelf.

Building a system

Team up the Mythos Three with two Mythos Two on-wall speakers for the left and right channels, and using the Mythos Gems as surround speakers. Add Definitive's SuperCube III subwoofer for hard-hitting bass.

Your home theater's most important speaker

The center channel speaker is the workhorse in a home theater system. It has to reproduce clear dialogue and special effects that keep your eyes and ears glued to the movie action. A high-quality center speaker is a great investment for any surround sound setup. Try to choose one that's as closely matched as possible to your front right and left speakers, so that as sound moves across the front stage, it stays seamlessly realistic.

Met Expectations

Crutchfield Customer Review (What's this?)

The Definitive Mythos 3 replaced a PSB center channel due to space limitations in our new house. Very impressed with the range and clarity of this speaker considering it's a much smaller enclosure than the PSB. A little pricey but worth it.

Crutchfield Customer Review (What's this?)

This center speaker was larger than expected, and well worth it. The sound coming from the center speaker is crisp, solid, and full. The frequency range as spec'ed seems quite true, and I'm impressed by the bass I'm getting out of it, along with my Mythos One tower speakers. As with the rest of the Mythos line, top sound and build quality.



Outstanding Center Channel Speaker

Written by: Wayne from St. Charles, IL on January 23, 2011

Crutchfield Customer Review (What's this?)

Dialogue is exceptionally clear and accurate -- even in a large room with high ceilings. I paired this speaker with the Definitive Mythos Fours (and a subwoofer and rear satellites); the combination of speakers provides a very satisfactory home theater experience. Highly recommended.

Driver Technology

Speaker Array: The Definitive Technology Mythos Three contains a D'Appolito array consisting of two high-definition 4-1/2 inch drivers housed in a air-tight enclosure. The drivers feature die cast Aluminum baskets, mono-polymer cones and finite element analysis optimized magnet structures for clear low distortion life-like sound. The drivers are pressure-coupled to two 4-1/2 inch planar low-bass radiators for exceptional bass extension not normally found in slim on-wall loudspeakers of this size. The bass roll-off of the Mythos Three 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. A 1-inch Pure Aluminum dome tweeter produces extended highs that reveal nuance and shimmer without a trace of edginess.

Break-In Period: The Mythos Three 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 Three enclosure is hand-polished gloss black aircraft-grade extruded aluminum with proprietary damping technologies that ensure total rigidity. All of its components are mounted on a resonance-free PolyStone baffle. All of 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 Three is equipped with a pair of gold-plated, 5-way binding posts to attach your receiver's speaker wire.

Mounting Options

Placement: The Mythos Three is designed for horizontal use and can be used as either a front or rear center-channels speaker. As a center-channel speaker, the Definitive Technology Mythos Three can be placed above or below your television.

Mounting: The Mythos Three is a table/shelf-mount and on-wall center-channel speaker. The Mythos Three come with easy-to-install mounting hardware that allows it to mount on the wall above or below your television. The Mythos Three comes with a wall mount bracket that 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. 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 Three has a simple built-in device which allows you to adjust the vertical angle of the speaker. There is an adjustable rubber-foot on the bottom-rear of the speaker cabinet. when you set the center-channel 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.
