Definitive Technology DI 8R
Definitive’s Disappearing™ In-Wall series speakers feature near-invisibility thanks to their small diameters, hidden flange design, and low profile micro-perf grilles.
They are as easy to install as traditional flanged flush-mount speakers, and don’t require custom sheetrock/spackle skills to install yet they are practically invisible.
The DI 8R grille is a mere 9-3/4" (24.8 cm)in diameter,noticebaly smaller than competing 8" in-ceiling speaker. With Definitive's DI Series you get more sound per square inch of visible speaker.
Buying from an authorized dealer has many benefits such as valid warranty coverage on your purchase and peace of mind.

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.
