Seven-Driver Array for powerful, accurate sound

A three-way, seven-driver system comprising four XTDD 3.5” woofers, two XTDD 3.5” mid/bass drivers, and a 1” aluminum dome tweeter projects robust, full-range sound over a wide area.


XTDD Drivers for spacious, dynamic sound in every seat

Ultra-stiff, 3.5” anodized aluminum dome woofers and midrange drivers eliminate break-up and broaden dispersion for crisp, clear sound and a spacious, enveloping soundstage.


Aluminum Oxide Dome Tweeter for exceptional definition and realism

A rigid, well-damped Dymension™ Series tweeter delivers 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.


Slim Profile and Adjustable Cabinet for a streamlined appearance

Symmetrically adjustable extensions expand up to 3.5” to aesthetically frame 75”-class television displays; an ultra-slim cabinet measures less than 2” deep, for a flush look.


Acoustically Optimized Cabinet for pristine sonic reproduction

A highly rigid, tuned, aircraft-grade aluminum enclosure houses a seven-driver array and ensures 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 horizontal or vertical wall-mount compatibility (mount included); Mythos LCR speakers present a streamlined appearance alongside and 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 and high-resolution music indoors and in covered outdoor areas.


Timbre-Matching for uniform voicing in any configuration

Consistent sound across Definitive Technology speakers 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.


Deep, Visceral Bass Sound you can feel

Add a Descend Series subwoofer to your Mythos LCR-75 speakers to seamlessly extend low-frequency performance.


Streamlined Surround Big sound without bulky speakers

Combine Mythos LCR-75 speakers with Dymension on-wall surrounds and a Descend subwoofer for a sleek surround setup that never interferes with your décor.


Total Atmos Immersion Sound above and around you

Add Dymension CI in-ceiling speakers for ultra-realistic overhead effects.
