Definitive Technology SuperCube® Reference
If you are assembling a reference home theater system with a high definition video projector or monitor along with an audio system that exceeds the sound quality and sheer visceral impact of premiere movie theaters, then this is absolutely the subwoofer for you.
The Reference incorporates a 14 inch SuperCube® Technology driver pressure coupled to two 14" Ultra Low Bass Radiators. The total piston area of this complement is an astonishing 460 square inches; equivalent to a 24-inch diameter woofer but with far greater speed, musicality and control than a single large diameter woofer could ever deliver.
With that much moving driver area, you can fill any domestic living space with loud, visceral, deep and musical bass.
We make buying audio entertainment easy - inquire to see if your purchase qualifies for discounts, upgraded shipping, and price matching.

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.
