Definitive Technology UIW RSS II In-ceiling/in-wall surround speaker with built-in back-box

Ultra-immersive surround effects

Designing your dream home theater? If you’re going in-wall or in-ceiling for your surround channels, check out Definitive Technology’s UIW RSS II. This unique bipolar speaker fires sound in multiple directions at the same time — ideal for immersive sound effects with movies and video games.

Pair the UIW RSS II with Reference Line Source speakers for seamless, voice-matched sound throughout your room.

Dual passive radiators help deliver extra punch

The UIW RSS II pairs two 4-1/2″ polypropylene midrange/bass drivers with two 1″ aluminum dome tweeters to produce the natural, revealing sound Def Tech is known for.

Dual 4-1/2″ pressure-coupled passive radiators help reinforce this speaker’s impressive bass output.

A built-in enclosure elevates performance

One of my favorite features of the UIW RSS II is the back-box that’s built onto the speaker.

This carefully designed enclosure helps the speaker deliver consistently focused, well-balanced sound no matter what kind of space is behind it in your ceiling. It also keeps dust and dirt out.

DIY installation

You can paint the included grille to have your speaker blend in with your room’s décor.
