Review Summary

Rated 4 out of 5

Ceiling mounted for Atmos

I held off for a while on an Atmos setup. I finally gave in and chose the DI 8R (2 pair) after reading recommendations on a forum. Installation is very easy. Sound quality is very good for surround (Atmos) setup. Power handling is great (separate power amp each pair). They also do an excellent job using DTS-X and Auro 3D modes blending very well with my speakers; ST-L, Mythos Ten, Mythos Gem XL (F Height, Side and Rear).

About Definitive Technology Disappearing DI

Take your audio experience to new heights with the Disappearing Series DI 5.5R Round 5.25" 2-Way In-Ceiling/In-Wall Speaker. This modern, sleek, and stylish speaker, designed by the reputable brand Definitive Technology, seamlessly integrates into your home's decor with its hidden flange design and low-profile white grille.

Despite its compact size, this high-quality speaker delivers a full, accurate audio experience that belies its size. It features a 5.25" BDSS Woofer that ensures room-filling fidelity, and a Pure Aluminum Dome Tweeter that provides clear, clean, and detailed sound.

The DI 5.5R speaker is tailored to your space with its Environmental EQ and pivotable tweeter. The Environmental EQ switch allows you to customize the tweeter output for your listening environment, while the pivotable tweeter ensures controlled directivity for clean, sparkling, distortion-free highs.

This elegant speaker is powered by our exclusive Balanced Double Surround System (BDSS) driver technology, which provides superior midrange/bass dynamics and detail. The rigid PolyStone basket ensures a sturdy launching pad for the powerful excursion, delivering more bass in less space while keeping the midrange detailed and responsive.

The DI 5.5R also features a sophisticated adjustable crossover network with custom, high-precision components for superior sonic purity. The specially-contoured AeroRing surrounding the BDSS driver precisely distributes natural, well-balanced sound by minimizing diffraction.

Installation is a breeze, whether it's new or existing construction, walls or ceilings, residential or commercial. The speaker's hidden flange design is as easy to install as traditional flanged flush-mount speakers, and the paintable grilles and frames allow for the final custom touch.

Experience the magic of invisible audio and astonishing performance with the Disappearing Series DI 5.5R Round 5.25" 2-Way In-Ceiling/In-Wall Speaker. It's not just a speaker; it's a disappearing act ready to entertain you.
