Definitive Technology DI 6.5R In-Ceiling Speaker/In-Wall Speaker

Let your surround system blend into your décor with the disappearing Series Definitive Technology DI 6.5R In-Ceiling Speaker/In-Wall Speaker. Get great sound from your favorite movie or movies with these Definitive DI 6.5R In-Ceiling Speaker/In-Wall Speaker. Experience smooth, dynamic sound without giving up an inch of floor space. Definitive Technology's DI 6.5R speaker installs flush in your ceiling. With its paintable, low-profile grille and hidden flange, it's practically invisible. The DI 6.5R pairs a pivoting 1" aluminum tweeter with a 6-1/2" 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. While other In-Ceiling Speaker/In-Wall Speaker fall short on sound quality and stealth, the Definitive DI 6.5R sets an impossibly high standard.

Building a Definitive Technology Home Theater Surround Sound System or a Multi-Room Music System
You can use the Definitive Technology DI 6.5R as part of a multi-room music system, or in a home theater system surround sound system. It's voice-matched with Definitive Technology's Mythos, BP, ProMonitor, Disappearing Series, DI Series and Bipolar speaker lines, so you can mix and match and build your system the way you like it.

Disappearing In-Ceiling Speaker/In-Wall Design
The DI 6.5R 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 6.5R 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 6.5R uses a 6.5" BDSS driver for wide-bandwidth accurate frequency response, broad dispersion, low distortion, and maximum detail retrieval. The 6.5" 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 6.5R's 6.5" BDSS driver has the bass output and dynamic range of a typical 8" driver.

Linkwitz-Riley Crossover Network
The Definitive Technology DI 6.5R'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 6.5R 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 6.5R 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.
