Definitive Technology Mythos Nine
Each Mythos® Nine contains two high-definition Balanced Dual Surround System (BDSS) 4-1/2" drivers (patent pending) that are pressure-coupled to two 4-1/2" x 8" racetrack-shaped planar Low-Bass Radiators for bass extension unheard of in a slim on-wall loudspeaker of this size.
Thanks to the performance advantages of its BDSS drivers and racetrack bass radiators the Mythos Nine significantly outperforms other on-wall speakers in its size and price class. The bass roll-off of the Mythos Nine 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.

About Definitive Technology
Definitive Technology has been committed to building superior sounding home audio and home theater loudspeakers since 1990, when the company was founded by Sandy Gross, Don Givogue and Ed Blais—lifelong audiophiles and experts in speaker design, acoustics and marketing. Definitive Technology loudspeakers are among the most positively reviewed and most often honored high performance loudspeakers on the market as well as being the best-selling premium home loudspeakers in the US.
Since its inception, Definitive has won an astounding number of awards and over-the-top enthusiastic reviews from Consumer Electronics industry associations as well as leading audio/video print magazines and websites. Frankly there are too many to list them all here but the photo on this page gets the point across.
Most recently a speaker system consisting of Definitive Technology Mythos STS SuperTowers, Mythos Nine center and Mythos Gem surrounds was awarded Sound & Vision magazine’s “Audio Product of the Year;” not merely “Speaker of the Year” but “Audio Product of the Year.” The system also won SoundStage!.com’s 2008 Reviewer’s Choice Award for Aesthetics and Sound. Home Theater magazine called the STS system “Crisp, Lush, Focused” and tagged it with a coveted Top Pick award. The STS also took home two Innovations Design and Engineering awards at CES 2009, one for High Performance Audio and the other for Home Theater Speakers. One industry award is an honor, five is a sweep.
