The Sound Quality Is Extraordinary

The UIW RCS IIs have been voiced by Definitive engineers (using the superb facilities of the Definitive Technology Advanced Research Facility) to the same high-end standards as all Definitive loudspeakers. The drivers and baffles are perfectly integrated into the design to minimize the diffraction problems that are inherent with most other in-wall loudspeakers.

Unpacking Your UIW RCS II Loudspeakers

Please Inspect For Shipping Damage

Each loudspeaker leaves our plant in perfect condition. Any visible or concealed damage most likely will have occurred in handling after it left the plant and should be reported at once to your Definitive dealer or the delivery company that delivered your loudspeakers. Please unpack your system carefully. Save all cartons and packing materials in case you move or need to ship your system. Record the serial numbers found on the back of the UIW RCS II Loudspeakers in the appropriate place on your warranty card.

UIW RCS II Applications

The UIW RCS II is designed to be mounted in ceilings and used as a front main left, right or center channel loudspeaker in a stealth home theater system of the highest quality. In addition, they can be used as rear or side surround speakers or as left and right stereo speakers.

UIW RCS II Positioning

Definitive’s UIW RCS II Loudspeakers are designed to be mounted in ceil-ings with excellent results. Because of their wide dispersion characteristics and other aspects of their superb sonic performance, mounting position in your room is very flexible. Due to the different requirements of the wide variety of room shapes and sizes, we recommend that you consult with the custom installation specialist at your Definitive Technology dealer regarding your own particular needs.

Your Complete Definitive Home Theater

For best results, we recommend that you use Definitive speakers in combination with your RCS IIs for the best overall sonic performance.

A popular choice for matching side or rear surround speakers is the Definitive UIW RSS II. In-wall or free-standing subwoofers may be used with the RCS II. Popular choices are the in-wall Definitive UIW Sub 10/10, UIW Sub Reference or our freestanding SuperCube subs.

Painting Your UIW RCS II Loudspeakers

The UIW RCS II Loudspeakers are easily paintable and are shipped with plastic paint masks (which should be retained even if you initially decide not to paint the speakers). The grille and frame must be painted separately, and for best results, prior to installation.

For the grille, spray painting is the recommended method. Follow the paint manufacturer’s directions for ventilation and correct spraying procedure. Be very careful not to clog the speaker grille with too heavy a coat of paint as this will impair system sonic performance.

For the frame, spray painting is preferred but brush or roller will also give good results. The supplied frame masks should be put in place to protect the speaker components for whichever method you choose.

Installation Procedure Overview

The RCS II is designed to be installed inside the ceiling of your home quick- ly and easily. Because of its superb sonic performance, installation location within your room is very flexible. Your room is not like anyone else’s room, and because of its unique size and shape will have its own requirements

for optimal sonic performance. We recommend that you consult with the Custom Installation Specialist at your Definitive Technology dealer regarding your special needs or if you are at all uncertain about the best and safest way to install your RCS II.

  • Installation of this product must follow all local and state building code requirements. We strongly recommend using a qualified, professional installer who is knowledgeable of local building codes.
  • The UIW RCS II is designed for mounting inline or at 90 degrees
  • to 16″ on-center ceiling joists.
  • If ceiling joists are wider than 16″ apart, you will need to shim (or frame in the enclosure) with appropriate framing material.
  • Before starting construction or modification of your ceiling, you should familiarize yourself with any applicable local fire and building codes.
  • Make sure the locations you select do not conceal studs, electrical wiring or plumbing. Prior to installation, hold the speaker in your chosen location to make sure it meets the clearance requirements around obstacles such as studs, corners, beams, lighting fixtures and door/window frames.
  • The speaker enclosure needs to be against joists or framing material on the 2 parallel sides that are to be fastened with the screws.
  • The clearance required on outside ceiling surface is 1″ around the cutout to clear the speaker bezel. On inside surface, 11/4″ of clearance is required to clear lock arms on the sides that will not be fastened to the joists or framing material.
  • Also note that the installation of the RCS II may require some modification of the joist structure in your ceiling. This should only be done by a competent professional who will configure the studs to maintain their structural integrity and make sure that everything is in compliance with all local and state building code requirements.
  • Speaker wire must be run inside your ceiling as part of the installation process of in-wall loudspeakers. Plan the connection before you start your loudspeaker installation.

FREQUENTLY ASKED QUESTIONS

Are definitive speakers any good?

The Definitive Technology BP-9060 Tower Speaker is most likely the best option for you if you have a strong passion for music and want a fresh listening experience. It’s one of the best speakers in the world and offers a once- in-a-lifetime audio experience.

Can you link two different ion speakers together?

Before attempting to connect two speakers, be careful to disconnect any Bluetooth devices. To enter Stereo Link mode, hold down the Link button for a few seconds. The word “LINK” will appear in the display once a link has been formed. Repeat these steps on the second Pathfinder 320 speaker after that.

Does Polk own Definitive Technology?

In 2012, Sound United was established with the straightforward goal of spreading joy through sound. We are one of the biggest audio corporations in the world today and the parent company of many illustrious audio brands, including Denon®, Marantz®, Bowers and Wilkins®, Polk Audio, Classé, Definitive Technology, HEOS, and Boston Acoustics®.

Are ceiling speakers a good idea?

Ceiling speakers may communicate exquisitely detailed music from overhead and even improve the surround sound of your speakers, despite their comparatively small size. Why not add a few to your home? Theaters even employ them to enhance the surround sound experience.

How do ceiling speakers get power?

No, ceiling speakers typically function as passive speakers, which means they lack internal amplifiers and are powered by speaker cables connected to an external amplifier. Each ceiling speaker is connected to the binding posts on the amplifier to do this.

Are speakers better in the ceiling or wall?

In-wall speakers have greater space for additional sound technologies and features because they are larger. In-wall speakers are frequently more potent and of greater quality as a result than in-ceiling speakers.

Do ceiling speakers need an amplifier?

An external amplifier that is wired via speaker cable to each ceiling speaker is required to power all of the ceiling speakers.

Should ceiling speakers be enclosed?

Yes. The sound quality of your in-ceiling speakers will be diluted if a black box is not installed, and this will cause noise pollution in other rooms in your house.

How many watts should my ceiling speakers be?

You need a stereo with at least 25 watts per channel with effective speakers or 40 watts per channel with non-efficient speakers for a space that is 18 feet by 18 feet and has 9-foot ceilings.

Do ceiling speakers need a subwoofer?

Even if ceiling speakers are capable of producing all the bass and low-end frequencies, a subwoofer will be helpful in handling them. Additionally, it significantly improves the overall sound quality of your sound system.

Where should I put my ceiling speakers?

To ensure a balanced sound, your in-ceiling speakers should be distributed evenly across the space. A single ceiling speaker could be adequate in a compact area. For the optimum sound dispersion in this scenario, position the speaker as close to the room’s center as you can.

Can you do a home theater with all ceiling speakers?

The listener-level speakers and above speakers must be separated for the optimal Dolby Atmos experience. It is not advised to install all of the speakers in the ceiling because the experience won’t be as good.

Where should you not put speakers?

At least two to three feet should separate speakers from the closest wall (especially if your speaker is in a corner). Many speakers have bass ports that face the back. A rear bass port that is too close to a wall will reflect sound waves, blurring time.

Are ceiling speakers OK for surround sound?

Of course, “yes.” To add that immersive extra layer of sound, simply point your in-ceiling stereo speakers in the desired location before configuring your system.

How many speakers should I put in my ceiling?

As a general rule, use one pair of ceiling speakers in spaces larger than 3 m2, and two pairs in spaces larger than 5 m2 for a more well-balanced sound.
