About the Definitive Technology DI 8R
Get room-filling, dynamic sound from a speaker that disappears into your décor. Definitive Technology's DI 8R speaker installs flush in your ceiling. With its paintable, low-profile grille and hidden flange, it's practically invisible.
The DI 8R pairs a pivoting 1" aluminum tweeter with a 8" driver for precise highs, full-bodied bass, and impressive dynamic range. The pivoting tweeter allows you to aim the sound directly towards your listening area, so you can fine-tune your system's sound.
Building a system
You can use the DI 8R as part of a multi-room music system, or in a home theater system. It's voice-matched with Definitive Technology's Mythos and Bipolar speaker lines, so you can mix and match.
An optional Definitive Technology DI 6.5R rough-in bracket is recommended for installing this speaker in new construction (brackets sold in pairs).
Did you know?
Your new speakers will probably sound better after several weeks of use than they do right out of the box. That's because the material surrounding the woofers will loosen up, allowing the drivers to move more fully. Definitive Technology estimates a break-in period of 24 to 48 hours of playback before the speakers will deliver optimum sound quality.

Definitive Technology DI 8R reviews
I installed these as replacements for two pairs of generic 6.5 in 2-way speakers in a living room and a kitchen. The Definitive Technology DI8R speakers give a significant improvement in sound quality compared to my older Aton speakers, much better bass performance and much better midrange definition. The older cutouts were 8.75 in, so I needed no enlargement to the ceiling holes; the fit was perfect. The total speaker depth is less than 4 inches, less than the former speakers, and the speakers installed easily with a Phillips screwdriver. The grille design is very low-profile with no bezel and attaches with magnets. The speaker surround is also very low-profile, so the speaker appearance is nearly flush with the ceiling surface. I am driving both pairs easily with a Sonos Amp which at 125WPC has ample power. The DI8Rs have an easy-to-drive 8 Ohm impedance which makes for a manageable demand on the amplifier in a parallel stereo setup.
Pros: -Excellent midrange and bass performance for a ceiling speaker. -Relatively small form factor, an 8-inch woofer unit that fits a cutout typical for smaller 6.5 inch driver units -Low depth requirements for tight ceiling spaces -Switchable bass output for corner installations -Low-profile grille, magnetic mount, paintable to match decor -Adjustable tweeter aiming for desired listening location -8 ohm impedance and good power handling -Works nicely with Sonos
Cons: -Not the cheapest speaker

Excellent sound, it really brought to life the experience of watching a movie at home. A must have if you are serious about having a Dolby Atmos system.
Pros: Great sound, bought to drive the additional ceiling channels for Atmos, however even when when listening to music they are capable of a beautiful sound for a great variety of genres.
Cons: None that I could think of.

The speakers are of excellent build quality, and the sound they produce is second to none. I have owned a number of different in-ceiling speakers in the various houses we've owned through the years, and these are the best I've owned yet. I purchased (6) of the DI 8R's for my theater room. During a recent repainting of the room, I had my painter match the ceiling color to the grilles. He didn't pay attention to my instructions, or those provided by DT and ended up ruining the grilles. I called DT support and they were incredibly helpful, and worked to get me new grilles right away. It's a rarity to see this level of customer service today. Thank you Definitive Technology. You've earned my loyalty not only for a great sounding speaker, but for OUTSTANDING customer service. TJ, thank you.
Pros: Build Quality, Sound Detail, Customer Service
Cons: None. While not the cheapest out there, you get what you pay for

I got these for our kitchen toward the end of our renovation project. With the overall cost of the project I was a bit price sensitive and hesitant to shell out this much money for a product without much name recognition (at least not for me). I have some fairly high-end Paradigms in our bar and wanted the kitchen speakers to compete. These are incredibly solid speakers with a big heavy magnet. The design is terrific. Virtually a flush mount and borderline trivial installation (well, I'd already run the wires during the renovation so I"m sure that helped). The sound is simply stunning. Very full and crystal clear with detailed highs and mids and the bass comes through like a champ when it's called upon. The sound reproduction is better than I ever expected for ceiling speakers. I would also recommend the enclosures mentioned by the other reviewer. I have not built any for them yet and there is a sense of being inside of a large speaker when you are in the bathroom directly above the kitchen (the speakers are in my kitchen ceiling directly below the bathroom floor). Not a real problem but may affect the sound a bit. I am thrilled that I spent the money on these, and I will buy another pair for other rooms as well (dining room, maybe to replace the Paradigm bookshelf speakers in the bar).
Pros: fantastic sound, easy installation, almost invisible appearance
Cons: cost is high (but worth it for me), you will want to buy more

Despite their intimidating price, I bought a pair for our kitchen in Oct 2010, with the goal of obviating the need for a subwoofer. Installation was a breeze. Low profile is amazing...protrudes just 1/8 inch! We listen to them for hours each day. Awesome, crystal-clear sound powered by zone 3 of our Denon AVR-4311 receiver. Their bass is tight and sounds great; but I can't tell if they truly reach the 26 Hz cited in the manufacturer's specs. Of course, they could never really substitute for a subwoofer, but they definitely hold their own. They're rated at 225 watts, so I tried max-ing out the 140 watt receiver's volume; had to stop well short of max because it was just way too loud to stand and the bass caused our ceiling's drywall (not the speakers, mind you) to vibrate too much! Our ceiling adjoins an unfinished attic, so I made an enclosure (to protect our investment from insulation, dust, etc,) by running 2X6's perpendicular to the joists and covering the "box" with 3/4-inch plywood. I'd like to believe this also enhanced sound quality by minimizing its dissipation into the attic. Tremendous speakers produce big sound from their small package. In one word, "Wow."

Overview: The Definitive Technology Disappearing In-Wall loudspeaker (DI Series) offers high-quality sound from a speaker that is barely visible when installed in a wall or ceiling. The Definitive DI Series incorporates a BDSS driver, pivoting tweeter, and integrated flanges behind an unobtrusive grille to provide audiophile-grade sound quality with an almost invisible appearance. The DI 8.5R is a mere 9-3/4" (24.8cm) in total visible diameter, which is noticeably smaller than competing nominal 8" models.
Disappearing In-Wall Design: The DI 8.5R features Definitive Technology's Disappearing In-Wall Design. The mounting flange thickness of the in-wall/in-ceiling loudspeaker is no more than 2.5mm (0.099") and is completely covered by the grille that stands a mere 3.5mm (approx 0.125") from the wall surface. The grille is "micro-perf", that while presenting an opaque appearance, actually has more open area than typical perforated metal grilles allowing the sound to pass through with less interference and better fidelity. Behind the metal grille is an acoustically transparent proprietary cloth scrim that effectively blacks the dark "shadow" of the black speaker parts from showing through the grille.
Pivoting Aluminum Dome Tweeter with Waveguide: The DI Series in-wall/in-ceiling loudspeaker uses Definitive Technology's proprietary ceramic-coated annealed aluminum 1" dome tweeter. The DI 35R tweeter is post mounted, and the tweeter housing is specially smoothed and shaped to use it as an extremely effective low-diffraction waveguide. The aluminum dome tweeter features a pivoting design which allows you to focus the sound toward or away from your listening area depending on the application.
BDSS Drivers: The DI 8.5R uses a 8" BDSS driver for wide-bandwidth accurate frequency response, broad dispersion, low distortion, and maximum detail retrieval. The 8" BDSS driver cone is supported by specially tuned soft rubber surrounds at both the outer and inner edges. The double surrounds allow the cone to have longer excursion without distortion. As bass output is a function of both a cone's diameter and excursion, the higher excursion BDSS system brings the benefit of higher bass output from smaller drivers. The DI 8.5R's 8" BDSS driver has the bass output and dynamic range of a typical 10" driver.
Linkwitz-Riley Crossover Network: The Definitive Technology DI 8.5R's second order (12dB/octave) Linkwitz-Riley crossover offers a smooth frequency and phase transition from driver to tweeter for natural midrange response and excellent off-axis performance. A Zobel network flattens the impedance curve of the speaker making it easier for today's digital amplifiers to drive the speakers. Custom tight-tolerance (+/- 5%) components are used throughout the crossover for superb unit-to-unit performance consistency. Superior metal film capacitors are used in the high-pass section and the Zobel network for extended high frequency response. Oversize inductors (coils) avoid saturation thereby maintaining the wide dynamic range capabilities of the driver.
Environmental EQ: The Environmental EQ switch (on top-frame of speaker) provides a 1dB broad bandwidth tweeter output lift or cut to compensate for highly absorptive or reflective acoustic environments.
AeroRing: The dimpled AeroRing is soft Sanoprene rubber and serves several important functions. First, it damps the basket/flange assembly nearest its thinnest part (the flange) to prevent resonance. Second it prevents the grille from rattling in the unlikely event that it makes contact with the speaker frame. It also provides a smooth transition for the waveform coming off the cone. Similar to the dimples on a golf ball that reduce turbulence to aid in longer flight, the dimples on the AeroRing promote smooth "laminar" air flow over the surface thereby reducing diffraction effects. The DI Series in-wall/in-ceiling loudspeakers sound clear, natural, and disperse their sound over a wide area.
PolyStone Basket: The driver basket, mounting flange, and mounting system of the DI 8.5R is one piece of cast PolyStone; Definitive's exclusive formulation of polymers and minerals that combine the rigidity and strength of metal with the resonance damping properties of plastics. As a result of the one-piece mounting system, the DI 8.5R offers increased strength, a compact size, and maximized cone area. Besides being more space efficient than multi-piece construction, it also contributes to the superior sound quality of the DI Series speakers.
Connections: The DI 8.5R features a pair of heavy-duty, gold-plated, spring-loaded wire terminals that have oversized holes to accept up to 10 gauge wire.
Definitive's GaussGrip System: Definitive's GaussGrip system securely holds the grille of the in-wall/in-ceiling loudspeaker in place with powerful magnets. Simply lay the grille over the speaker and its secure. Taking off the grille is just as easy and fast; no special tools that can chip the grille paint are required. All you need to remove the grille is your fingers.
Paintable Grille The DI Series in-wall/in-ceiling loudspeaker's white "micro-perf" cloth grille can be spray painted to match the color of your wall or ceiling without any loss of sound quality. Simply remove the grille from the speaker and place it on a drop cloth, newspaper, or plastic sheet and spray paint it with canned spray paint that closely matches the desired finish/color; or with indoor latex paint using an airbrush or spray gun (available at home improvement stores). The paint must be diluted to a 6:1 ratio of latex paint to water. Do not remove the backing cloth (scrim). Apply the paint in a series of thin coats sprayed at 45-60 degrees from the grille surface, allowing each coat to fully cure before applying additional coats. To ensure that the paint distribution is evenly applied, each coat should be applied from 4 different directions (N,S,E, & W) to ensure an even coverage on the grille.
Note: The grille must be spray painted detached from the speaker. Do not paint the grille with a brush or roller.
Applications: The DI 8.5R can be used as a pair of stereo speakers for your music or as a pair of front and surround speakers in your home theater system.
Mounting: The DI 8.5R can be mounted in-ceiling using the integrated rotating clamps and four mounting screws, or using an optional pre-construction bracket (7358RRIK, sold separately). A cutout template is supplied to help you cut a 8-3/4" diameter hole. You will need to allow at least 1/2" of space around the cutout and have at least 3-1/4" of clearance for mounting depth (using 1/2" thick mounting surface). You should allow at least 7/8" from the edge of the cutout to nearest obstruction inside the mounting surface.
Optional Pre-Construction (Rough-In) Brackets: The optional DI Series pre-construction rough-in brackets provide a simple way to mount these in-wall/in-ceiling loudspeaker during pre-construction or remodeling of your home. The center rings are fabricated from heavy duty painted stamped steel. There are no sharp metal edges to cut an installer's hands and they are ultra rigid, so that when drywall is laid over and cut the brackets will not bend or break. The two 12" wings are painted perforated metal that snap onto the center ring in a variety of positions to cover almost any installation. The wings can be attached with nails, staples or screws; and can be bent and easily trimmed with tin snips. They are also thin enough to make stud notching simple. The wire tie loop easily breaks away when the speaker is installed. DI Rough-in Brackets are packaged two to a carton.
