Definitive Technology DI 3.5R In-Wall Speakers

The New Definitive Technology DI 3.5R can give you rich, dynamic sound throughout your home without sacrificing an inch of floor space. The DI 3.5R 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.

Pivoting Aluminum Dome Tweeter with Waveguide

The DI Series in-wall/in-ceiling loudspeaker uses Definitive Technology’s proprietary ceramic-coated annealed aluminum 3/4″ dome tweeter. The DI 3.5R 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 3.5R uses a 3.5″ BDSS driver for wide-bandwidth accurate frequency response, broad dispersion, low distortion, and maximum detail retrieval. The 3.5″ BDSS driver cone is supported by specially tuned soft rubber surrounds at both the outer and inner edges.

Linkwitz-Riley Crossover Network

The Definitive Technology DI 3.5R’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.


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.

Definitive Technology DI 3.5R Rough-In Bracket – Pair

The DI Series rough-in brackets were custom designed from the ground up to be easy to install. The “arms” are metal mesh and can easily be attached to wood or metal studs using nails, dry-wall screws, or construction staples. The arms easily detach and can be positioned at various points around the bracket to accommodate unusual stud/joist locations. The center ring is heavy gauge steel that will not bend or break with rough handling and sloppy drywall cutting by subcontractors. The convenient wire tie loop is scored to allow easy snap off once the speaker is installed.

Metal Rings

The center rings are fabricated from heavy duty painted stamped steel. There are no sharp metal edges to cut an installer’s handsre and they are ultra rigid, so that when drywall is laid over and cut the brackets will not bend or break. The center ring quires a 3.8125″ diameter cutout.

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.
