Installation Considerations

Features and Benefits

DSFG Defeat (HD•CTR) Main/Surround Configuration (HD•LRS)

Both the HD•CTR and HD•LRS feature crossover mounted switches which cus- tomize the response of the speaker. In the HD•CTR, the switch controls whether the Directed Sound Field Geometry feature is On or Off. (It is useful to switch it Off when the speaker is installed at ear level, for exam- ple, behind a perforated screen). In the HD•LRS, the switch sets the speaker’s response for Main (front) or Surround. The Surround setting manipulates the response of the speaker to provide a diffuse sound field.

BumpBack™ Woofer Magnet(s)

Niles engineers have utilized a unique magnet construction allowing far greater “throw” or voice coil excursion. This allows a new level of deep bass perfor- mance to be achieved.

X-Matrix™Reinforced Baffle

The X-Matrix Baffle design uses specially molded ribs to add rigidity to the baffle assembly. The end result is better bass and improved midrange detail.

Absolutely Flush to the Wall

tions simple and fast. A supplied template assures fast and accurate hole cutting. The bracket slips behind the drywall and the screws secure the bracket to the frame, sandwiching the drywall between them. The speaker baffle attaches to the frame, and the grille mounts over the speaker.

Three Stage Installation System for Remodels or New Construction

You install only the parts you need for a particular stage of construction. When the framing and wiring are finished, you install the bracket. After the drywall is up, but before the painter begins to paint, you install the frame and provide the rustproof aluminum grilles to the painter so that they can be painted to match the sur- roundings. Only when construction is completely finished do you put the valu- able speaker in the wall. You don’t have to mask or prep the speaker for painting, and worries about theft during the final phases of construction are never an issue!

Appearance

The unique mounting system of the HD loudspeakers powerfully clamps the frame to the bracket, sandwiching the wall mate- rial between them. Because the clamping action is totally uniform around the frame, there are no shadows or gaps between the wall and the frame. Additionally, the Niles mounting system is carefully optimized to stiffen the surrounding drywall and pre- vent it from resonating. You hear only the music, not the drywall.

Easy Retrofit Installation in your Existing Home

Designed for ease of installation, the Niles mounting system makes retrofit installa-

installs discreetly behind the aluminum grille and therefore minimizes wall clut- ter in your home. When you want to control your equipment, you simply point your remote control at the speaker from up to 15 feet away.

Low Diffraction, Paintable

Aluminum Grilles

HD speakers come standard with alu- minum grilles. The grille has hundreds of precisely sized perforations, creating an acoustically transparent grille. The alu- minum construction is 100% rustproof.

Recommended Amplifier Power

For satisfactory performance, we recom- mend an amplifier with a power rating of ten to one hundred fifty watts. Curiously, most speakers are not damaged by large amplifiers but by small amplifiers. If your system is playing loudly, a small amplifier will run out of power very quickly. When an amplifier runs out of power it creates damaging “clipping” distortion. A more powerful amplifier will play at the same volume without distorting. See the section on operating the speakers for more infor- mation about clipping distortion.

Speaker Wire

Use 2-conductor speaker wire when con- necting HD speakers to your receiver or amplifier. For most applications, we rec- ommend you use 16 or 18 gauge wire. For wiring runs longer than 80 feet we recommend 14 gauge wire. The spring loaded terminals of the HD speakers will accommodate up to 12 gauge wire directly. Larger sizes can be accommodat- ed via pin connectors.

When you run wire inside walls, special jacketing (CL-2 or CL-3) is required to both protect the wire and for fire preven- tion. In some areas conduit is required. For a trouble-free installation, low voltage wire such as speaker wire must be run in accordance with the National Electrical

HDCTR, HDLRS specifications

Niles Audio has a longstanding reputation in the realm of home audio solutions, and its HDCTR and HDLRS models are exemplary representations of the brand's commitment to high-performance audio technology. These models cater to enthusiasts looking for comprehensive audio experiences with cutting-edge features and advanced engineering.

The Niles HDCTR, a center channel speaker, is designed to provide clarity and depth for dialogue and soundtracks in home theater setups. One of its main features is the use of advanced, high-efficiency drivers that reproduce a wide frequency range, ensuring that every nuance in sound is captured. The speaker is engineered with a high-performance 6.5-inch woofer coupled with dual 1-inch soft dome tweeters, allowing it to deliver an impressive audio performance whether you’re watching movies or listening to music.

On the other hand, the HDLRS model stands out as a pair of surround speakers that enhance the immersive experience whether in a stereo or surround sound configuration. Each speaker utilizes a 6.5-inch woofer and dual 1-inch tweeters for a balanced sound stage. The design of the HDLRS also allows for flexible placement options, making it easy to integrate into diverse home environments.

Both models feature Niles' proprietary technologies that minimize distortion and improve dynamic range, enhancing overall listening pleasure. The HDCTR is equipped for wall-mounting, allowing for seamless integration into your home theater system. Meanwhile, the HDLRS includes adjustable mounting brackets which enable precise angling to optimize sound directionality.

In terms of build quality, both speakers boast a robust design with attractive aesthetics that can complement any room decor. The cabinets are crafted from durable materials that not only withstand the test of time but also help to reduce unwanted resonance, thereby improving audio fidelity.

Furthermore, the low impedance design of the HDCTR and HDLRS models ensures compatibility with a wide range of AV receivers, making them accessible for both professional installers and casual users alike. This level of flexibility makes them excellent choices for those looking to elevate their audio experience, whether for casual listening or serious home theater setups.

Overall, Niles Audio's HDCTR and HDLRS speakers embody a perfect blend of style, performance, and technological innovation, catering to audiophiles who seek unmatched sound quality and versatile solutions for their audio needs.
