Definitive Technology Mythos 3C-65 Ultra-Slim On-Wall Passive Sound Bar Review – Experience next-level cinematic audio with the diva of ultra-slim sound bars. The Mythos 3C-65 elevates 65"-class TVs with premium acoustics, designer aesthetics and weather-resistant robustness, striking the perfect balance between form and function.

Design and Build Quality

The Mythos 3C-65 impresses with an ultra-slim aluminium cabinet measuring less than 2" deep, effortlessly blending beneath any 65"-class display. Symmetrical, adjustable-width extensions (up to 6.75") ensure a seamless aesthetic match. Its micro-perforated, powder-coated steel grille exudes minimalist elegance, while the IP66-rated enclosure guarantees worry-free performance in covered outdoor environments.

Precision Acoustic Engineering

Underneath its refined exterior lies a meticulously tuned three-way, 13-driver array. Eight 3.5" XTDD aluminium dome woofers and midranges deliver expansive dispersion, crisp clarity and low distortion. Three 1" aluminium oxide dome tweeters housed in Dymension™ Series chambers provide smooth extended response, pin-point imaging and lifelike transients. Advanced precision crossovers calibrate each driver for optimal sonic coherence, producing a neutral, balanced soundstage that belies the bar’s slim profile.
