Ultimate In-Wall Reference Series

Featuring the same legendary driver technology as our finest floorstanding speakers, Ultimate In-Wall Reference Series loudspeakers are built to thrill the most demanding home theater and home audio lovers — invisibly.

Invisible Sound, Uncompromised

Breathtaking
Performance

UIW Reference Series loudspeakers deliver uncompromising sound from a high-technology flush-mount enclosure that disappears into the environment. They provide thrilling sound with room-filling bass, stunning detail, and theater-reference volume levels that rival the best freestanding speakers without any of the clutter.

Flagship Definitive Technology Drivers
for reference loudspeaker performance

Ultimate In-Wall Reference Series loudspeakers are designed with the same driver technologies as our flagship floorstanding speakers and deliver the same ultra-realistic theater experience.

1" Aluminum Dome Tweeter

Definitive Technology aluminum dome tweeters deliver a clear, precise high frequency response. Their ultralight, rigid construction enables them to play significantly higher frequencies than we can hear, providing effortless, distortion-free highs.

Wave Launch & Bipolar Technologies
for a reference theater presentation

UIW RCS in-ceiling loudspeakers feature our patented Wave Launch technology, employing precisely angled baffles and drivers to deliver an astonishingly convincing theater-like experience.

UIW RSS bipolar in-wall/in-ceiling loudspeakers fill the room with a perfect combination of direct and reflected sound for stunning surround effects.

In-Wall Subwoofer
for thunderous bass

A seamlessly-voiced complement to our in-wall/in-ceiling speakers, the IW Reference subwoofer plumbs the lowest octaves of music, movies, and games — unleashing massive, thunderous bass.

Fully Enclosed
for powerful sound where you want it

Like high-end freestanding speakers, UIW Reference Series speakers are fully enclosed and sealed with dense, acoustically inert, anti-resonant, anti- vibration Medite® wood. You’ll hear loud, accurate, uncolored midrange and tight, powerful bass with no distortion or buzzing.

Installation Flexibility

Customize
to your home

Whether new or existing construction, walls or ceilings, residential or commercial, UIW Reference Series loudspeakers feature simple, secure installations. From metal pivoting lock arms to paintable grilles and frames to fully sealed enclosures, Definitive Technology engineers designed speakers that put installation simplicity on equal footing with sound quality.

Rotating Arrays
for optimal directivity

When RSS Bipolar models are installed in the ceiling, the driver arrays can be rotated 90° to optimize performance for your listening area.

Fully Sealed
for predictable, intentional integrations

UIW Reference Series loudspeakers are fully enclosed in sealed Medite® wood, a dense, non-resonant cabinet material stronger than MDF. With speaker enclosures, sound will radiate forward into the room precisely as the installer intends. Additionally, we are proud that Medite is a sustainable, environmentally-friendly compressed wood fiber material with more than 90% pre-consumer recycled content and zero formaldehyde.

Custom Flexibility
for any configuration

Whatever your décor, the perfect UIW Series experience awaits you. Choose an RCS model for in-ceiling speakers that convincingly emulate freestanding speakers. Choose an RSS model for a versatile, larger-than-life Bipolar theater performance, either in-wall or in-ceiling. Choose an RLS in-wall model for a true reference direct-radiating floorstanding speaker experience. Match any with the IW Sub Reference or IW Sub 10/10 subwoofers for earth-shaking bass. Create any mix of models for your home, all with matching voicing, the combinations limited only by the imagination.
