Sleek and Streamlined

Big, Wide Sound

The Mythos 3C-85 three-channel passive sound bar elevates home theater experiences indoors and in covered outdoor areas. Combining the three front channels of a home theater system in a single cabinet, this ultra-slim, on-wall, three-way speaker blends high-performance sound and designer aesthetics in a weather-protected, adjustable-width rigid aluminum enclosure.

Thirteen-Speaker Array
for powerful, accurate sound

A three-way, 13-driver system comprises two XTDD 3.5” mid/bass drivers and one 1” aluminum oxide tweeter for each left/right channel. The center channel features two XTDD 3.5” mid/bass, four XTDD woofers, and a 1” aluminum oxide tweeter. Together they project robust, full-range sound over a wide area.

XTDD Drivers
for spacious, dynamic sound in every seat

Ultra-stiff anodized aluminum dome woofers and midrange drivers eliminate break-up and broaden dispersion for crisp, clear sound and a spacious, enveloping soundstage.

Slim Profile and Adjustable Width
for a streamlined appearance

The 3C-85’s ultra-slim, wall-mount cabinet measures less than 2” deep; symmetrically adjustable extensions expand up to 6.75” to perfectly align with the dimensions of 85-inch and larger-class television displays, for a cohesive look.

Acoustically Optimized Cabinet
for pristine sonic reproduction

A highly rigid, tuned aircraft-grade aluminum enclosure houses a 13-speaker array with each channel in its own acoustic chamber. You’ll experience the truest sound, uncolored by cabinet resonances.

Luxury Finishes and Sharp Styling
for elevating any living space

With clean, modern aesthetics; refined anodized aluminum finishes; and VESA mount compatibility (VESA and wall-mount brackets included); this sleek, wall-mount sound bar presents a streamlined appearance under your TV.

IP66-Rated Protection
for security in the elements

IP66-rated protection against dust and high-pressure water streams means you can enjoy stunning home theater sound indoors and in covered outdoor areas.

Timbre-Matching
for uniform voicing in any configuration

Consistent sound across Definitive Technology models gives you the flexibility to mix and match speakers to build the ultimate system or a starter system that can expand as your needs grow.

Aluminum Oxide Dome Tweeters
for exceptional definition and realism

Rigid, well-damped Dymension™ Series tweeters deliver smooth extended response, crisp transients, and pin-point imaging for cohesive, lifelike sound that draws you inside the action.

Precision Crossovers
for dynamic, balanced response

Meticulously tuned crossovers optimize systems for the most efficient driver performance. You’ll experience richer, fuller, sound—the kind you’d expect from full-sized speakers.

Total System Scalability
for elevating any home cinema

Take a minimalist approach with a simple, all-in-one on-wall system or build the ultimate home theater.

All-In-One Sound Bar
Big sound in an ultra-slim cabinet

Use a Mythos 3C-85 on its own or with a Descend subwoofer for larger-than-life sound in a low-profile, all-in-one system.

Simple Surround
Sound all around you

Combine a Mythos 3C-85 with Dymension on-wall speakers and a Descend subwoofer to fill the room with spacious, enveloping sound without filling the room with bulky speakers.

Total Immersion
A 360-degree soundstage

Add Dymension on-wall speakers, Dymension CI in-ceiling speakers, and a Descend subwoofer to build the ultimate Atmos system.

Mythos three-channel passive sound bars are wall-mountable or compatible with VESA mounts, allowing them to easily attach directly to either a wall or TV for a sleek, cohesive look.
