Definitive Technology DI 5.5BPS In-Wall Speakers

Definitive Technology’s DI 5.5BPS bipolar speaker. This speaker installs flush in your wall, and can blend seamlessly into almost any decor. With its paintable, low-profile grille and hidden flange, it’s practically invisible.

Bipolar Surround In-Wall Loudspeaker

The Definitive Technology DI 5.5BPS offers Bipolar sound dispersion which is ideal for side or rear surround channel applications, or anywhere extremely broad sound coverage is desired.

Disappearing In-Wall Design

The DI 5.5BPS 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 4.0mm (approx 0.165″) from the wall surface.

Pivoting Aluminum Dome Tweeter with Waveguide

The DI Series in-wall loudspeaker uses two Definitive Technology’s proprietary ceramic-coated annealed aluminum 1″ dome tweeters. The DI 5.5BPS tweeters are post mounted, and the tweeter housing is specially smoothed and shaped to use it as an extremely effective low-diffraction waveguide.

BDSS Drivers

The DI 5.5BPS uses dual 5.25″ BDSS drivers for wide-bandwidth accurate frequency response, broad dispersion, low distortion, and maximum detail retrieval. The 5.25″ BDSS driver cones are 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 5.5BPS’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.


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. “laminar” air flow over the surface thereby reducing diffraction effects. The DI Series in-wall 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 5.5BPS 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 5.5BPS features a pair of heavy-duty, gold-plated, spring-loaded wire terminals that have oversized holes to accept up to 10 gauge wire.


 Definitive Technology DI 5.5BPS Rough – In Brackets – Pair

Definitive Technology DI 5.5BPS 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 6.9375″ (W) x 12.6875″ (H) rectangular 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.
