Definitive Technology DI 5.5LCR In-Wall Speakers

Definitive Technology designed this unobtrusive in-wall speaker specifically for premium sound quality in home theater environments. Install a pair on either side of your TV and use one below or above your TV as a center channel. Each speaker installs flush in your wall. With its paintable, low-profile grille and hidden flange, it practically disappears in your room.

Disappearing In-Wall Design:

The DI 5.5LCR features Definitive Technology’s Disappearing In-Wall Design. The mounting flange thickness of the in-wall loudspeaker is no more than 2.5mm (0.099″) and is completely covered by the grille that stands a mere 3.5mm (approx 0.145″) from the wall surface. Pivoting Aluminum Dome

Tweeter with Waveguide:

The DI Series in-wall loudspeaker uses Definitive Technology’s proprietary ceramic-coated annealed aluminum 1″ dome tweeter. The DI 5.5LCR 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 5.5LCR uses two 5.25″ BDSS drivers for wide-bandwidth accurate frequency response, broad dispersion, low distortion, and maximum detail retrieval. Each 5.25″ 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.

Linkwitz-Riley Crossover Network:

The Definitive Technology DI 5.5LCR’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.

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.


AeroRings around the 5.25″ drivers are 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.

PolyStone Basket:

The driver basket, mounting flange, and mounting system of the DI 5.5LCR 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.


The DI 5.5LCR 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 Gauss Grip System:

Definitive’s GaussGrip system securely holds the grille of the in-wall 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 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.


Definitive Technology DI 5.5LCR Rough – In Brackets

The mounting brackets 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 mounting bracket requires rectangular cutout that measures 6.5″ (w) x 14.375″ (h) x 0.375″ (d). The outer dimensions of the mounting bracket are 8.625″ (w) x 15.8125″ x 0.8125″ (d).

Mounting Arms:

The metal mesh mounting arms 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. The mounting arms measure 12.4375″ (w) x 1.9375″ (h) x 0.5625″ (d).
