Mythos Series

The Mythos® Series blends high-performance Definitive Technology sound and designer aesthetics to elevate your home theater experience.

Look for the arrival of the Mythos Series in October 2023.


Modern, Streamlined Design

Sound Quality

Mythos Series passive, on-wall sound bars and on-wall LCR speakers deliver iconic Definitive Technology sound with the power, clarity, dynamic range, and extended response you’d expect from full-size systems, in sleek, ultra-slim designer cabinets. Their IP66-rating makes them ideal for indoor and covered outdoor home theater applications as well as whole-home sound systems and light commercial applications.

Multiple Driver Arrays
for powerful, accurate sound

XTDD Drivers
for spacious dynamic sound in every seat

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


Slim, Adjustable Cabinet with a Luxury Finish
for sharp styling and a streamlined appearance

Mythos speakers measure less than 2” deep, with all models featuring symmetrically adjustable extensions that expand to match the dimensions of 65–90-inch displays. Speakers feature clean, modern styling, with a refined anodized aluminum finish and acoustically transparent, micro-perforated metal grilles for a sleek, streamlined look to elevate any living space.


Acoustically Optimized Cabinet
for pristine sonic reproduction

A highly rigid, tuned aircraft-grade aluminum enclosure houses the speaker array, with each channel in its own acoustic chamber on three-channel models, and ensures the truest sound, uncolored by cabinet resonances.


IP66-Rated Weather Protection
for security in the elements

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


Design Your Dream System
for a personalized home theater or music system

With timbre-matching across the Definitive Technology line, you can mix and match Mythos models with Dymension or Dymension CI Series speakers and Descend Series subwoofers to build the ultimate system, or a starter system that can expand as your needs grow.

Flexible Configuration
for home or commercial applications

With three-channel passive sound bars and LCR models, IP66-rating, and timbre-matching to other Definitive Technology speakers, Mythos Series provides the flexibility for indoor and outdoor home theater, whole-home sound systems, and light commercial applications.
