Definitive Technology DI 5.5LCR
You want great sound everywhere in your home, but you may not always have room for or want the visual intrusion of free-standing speakers. Built-in flushmount speakers seem to be the answer but in practice they don't exactly disappear in the room, in fact many "in-wall" speakers call attention to themselves and create friction between your decorator and your audiophile sensibilities. Worse yet, most built-in speakers fall short on the performance end as well. Would Definitive allow you to suffer with bad sound? Oh no, no, no!
The Disappearing In-Wall models feature Definitive's most advanced technologies such as Balanced Dual Surround System (BDSS) mid/woofer drivers and pivoting pure aluminum dome tweeters for spectacular audio performance far beyond traditional flush-mount speakers.
Definitive's exclusive Balanced Dual Surround System (BDSS) driver technology permits these new flush mount speakers to deliver more bass output and dynamic range than larger drivers. For example, the DI 5.5LCR's two 6-1/2" drivers have the output, bass, and dynamics of a 10" traditional speaker.
With a pivoting 1" pure aluminum dome tweeter featuring a specially shaped housing that avoids the diffraction distortions of traditional post-mounted tweeters, and a sophisticated adjustable crossover network, the Disappearing In-Wall models deliver the kind of lifelike sonic performance and broad even dispersion that have made Definitive Technology the most highly reviewed speaker brand in the USA.
The DI 5.5LCR has been optimized for use as stereo Left/Right/Center front stage speakers while the matching DI 5.5BPS is a Bipolar technology speaker ideal for surround channel use. Together these models realize the dream of premium performance in a practically undetectable built-in home theater system. All models in the DI Series share the same accurate sonic signature so you can mix and match any combination of models to meet your exact application.

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.
