Definitive Technology DI 5.5S In-Wall Speakers

Definitive Technology’s DI 5.5S speaker installs flush in your wall. With its paintable, low-profile grille and hidden flange, it’s practically invisible.

Disappearing In-Wall Design

The DI 5.5S 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 0.145″) from the wall surface. 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 5.5S 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 5.5S uses a 5.25″ BDSS driver for wide-bandwidth accurate frequency response, broad dispersion, low distortion, and maximum detail retrieval. The 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 5.5S’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.

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 5.5S 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 5.5S offers increased strength, a compact size, and maximized cone area.

Definitive Technology RBAF DI 5.5S Rough-In Brackets

Definitive Technology DI 5.5S in-wall speakers. Use the adjustable arms to attach the bracket to studs or joists before the drywall goes up.

Metal 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 a 6.375″ x 6.375″ square cutout.

Mounting Arms

The metal mesh mounting arms snap onto the metal bracket 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.
