UIW Reference Series Speakers

Definitive UIW Reference Architectural Speakers are perfect for bringing spectacular-sounding, high-performance "invisible" home theater systems into every room in your house.

Build a serious "stealth" home theater system by matching any combination of our Reference Series in-wall speakers, such as the in-ceiling UIW RCS II, UIW RCS III, UIW RSS II, UIW RSS III, UIW RLS II or UIW RLS III across the front stage as left, center and right channel speakers. This sleek system will deliver excellent bass without a separate subwoofer. But we would be remiss if we failed to encourage you to add an IWSub In-Wall Subwoofer (IWSub Reference, IWSub 10/10 and SubAmp 600) System, or even a couple SuperCube Subwoofers for even more dynamic bass performance!

IWSub Reference
Fully Enclosed Reference In-Wall Powered Sub with 13" Woofer

The IWSub Reference In-Wall is a booming bass-driven powerhouse that will disappear in your room. It has a non-resonate sealed medite enclosure and an eye-catching paintable bezel and grille. Inside the completely self-enclosed in-wall sub is the technical brainpower derived from the SuperCube Subwoofers. It includes a special shallow-depth, long excursion active13" driver tied with a 13" pressure driven infrasonic radiator. Combined, these features result in tight musical excellence. The IWSub Reference In-Wall installation is straightforward and favors both newly constructed and existing walls.

“Sound so solid and clean you’ll think it’s coming from a higher power”
—Peter Pachal, Sound & Vision

Ceiling Speaker (RCS II) is intended for use as an in-ceiling front main left, center or right channel speaker, as well as a rear or side surround speaker in custom installed home theater systems of the highest quality. In addition, it can be used as a superb left or right speaker in a high quality stereo music system.

“[The RCS II is] destined to shift every paradigm there is regarding ceiling speakers.”
—Chris Martens, The Perfect Vision

Like our other Reference Architectural Series speakers (IWSub 10/10, IWSub Reference, RLS II and RLS III), the RCS II is a totally non-resonant sealed medite enclosure, which in this case easily and attractively installs flush into the ceiling in either new or existing construction. It features a D’Appolito driver array angled down and aimed at the listening area (two 5-1/4" cast-basket bass/midrange drivers and a 1" pure aluminum tweeter) as well as two 6-1/2" pressure-coupled planar low bass radiators. The precisely configured dual angled baffles incorporate a uniquely effective acoustic treatment which combines a computer-optimized ribbed surface with special dampening panels in order to achieve a linear uncolored sound combined with boxless three-dimensional imaging in which acoustic events seem to effortlessly float in space. In fact, the overall sonic performance of the RCS II is truly remarkable, combining breath-taking dynamics, engrossing musical subtlety and amazingly spacious imaging that totally belies its in-ceiling configuration.

“sounded great...I was tremendously impressed”
—Fred Manteghian, Ultimate AV

In addition, the RCS II with its active driver/bass radiator combination achieves an extended low-frequency response, which is deep and dynamic with a smooth and controlled roll-off that allows it to seamlessly blend with a subwoofer with a quality that has never been previously achieved in an in-ceiling system. Of course, our in-wall IWSub 10/10 or UIW Sub Reference are a perfect complement to the RCS II for unmatched performance in a stealth home theater.

“Think of the RCS IIs as jaw-droppingly good home theater speakers that just happen to live in the ceiling”
—Chris Martens, The Perfect Vision

They feature two 4-1/2" cast basket active drivers and a Pure Aluminum tweeter on an angled baffle aimed at the listening area. Proprietary Wave Length (patent pending) baffle geometry and acoustic treatment materials serve to create the illusion that the speakers are directly in front of the listener rather than up in the ceiling. The active drivers are pressure-coupled to two 5-1/4" race-track Low-Bass Radiators for exceptional bass and perfect blending with free-standing or built-in subwoofers.

The UIW RSS II is another important new addition to Definitive’s Reference Architectural Series. The RSS II is intended for rear or side surround use in 5, 6, 7, 8, 9 or more channel custom-install systems of the highest quality. Like the other Reference Architectural Series speakers, the RSS II is a totally non-resonant sealed medite enclosure, which easily installs flush into walls or ceilings in either new or existing construction. It features a curved angle bipolar array, which is perfect for movie and music surround use because it provides an ideal combination of direct sound for specificity and localization and ambient sound for enhanced spaciousness.

The RSS II delivers uniquely enveloping surround performance totally immersing the listeners in a complete 360-degree soundstage. Walls seem to disappear and the listening room will be almost magically transformed into the location of the original sonic event. The curved aspect of the bipolar array further improves dispersion into the room. When installed in the ceiling, the direction in which the driver arrays face can be rotated 90 degrees in order to optimize the performance depending on the specific location of the speakers in relation to the seating area.

Each RSS II bipolar surround speaker contains two complete 3-way full-range systems for a total of 6 driver/radiators in each speaker. The RSS II’s dynamic, spacious and uncolored sonic signature has been specifically engineered to blend perfectly with any of Definitive’s loudspeakers whether freestanding, in-wall or in-ceiling for an amazing lifelike sonic experience.
