Definitive Technology DI 5.5LCR In-Wall Speaker Reviewed


When I decided to install a home theater system, I opted for in-wall and in-ceiling speakers. There are many advantages to using in-wall speakers for a surround sound system, including a clean, nearly invisible aesthetic for both the speakers and...

The DI 5.5LCR is nearly invisible. For the slightly higher cost of installation, you get a clean look with no visible wires and nothing to have knocked over ; These in-wall speakers deliver great sound ; The speaker is a great value, since the speaker...

Installation often requires cutting through walls and snaking wires through studs, which can be costly ; These in-wall and in-ceiling speakers are not enclosed, so sound may leak into adjacent rooms ; In-wall subwoofers, even the fully enclosed subs...

If you're building an home theater system from scratch (even in an existing, older room) and a nearly invisible, zero-floor-space design is your goal--but you don't want to sacrifice sound quality and aural impact--I highly recommend the DI Series from...

Awesome sound


Truly great sound for the small size speakers. Great for larger rooms. DI35R is enough for smaller rooms but DI55R has a much better sound.

Product Specifications

You want great sound everywhere in your home, but you may not always have room for or want the visual intrusion of free-standing speakers. Built-in flush mount speakers seem to be the answer but in practice they don't exactly disappear in the room, in fact many "in-wall" speakers call attention to themselves and create friction between your decorator and your audiophile sensibilities. Worse yet, most built-in speakers fall short on the performance end as well. Would Definitive allow you to suffer with bad sound? Oh no, no, no! Definitive's Disappearing In-Wall series speakers feature near-invisibility thanks to their small diameters, hidden flange design, and low profile micro-perf grilles. They are as easy to install as traditional flanged flush-mount speakers, and don't require custom sheetrock/spackle skills to install yet they are practically invisible. The DI 5.5R grille is a mere 7-3/8" in diameter, about the same visible size as competitive nominal 4-1/2" in-ceiling speakers. With Definitive's DI Series you get more sound per square inch of visible speaker.
