Niles new DS Directed Soundfield loudspeakers feature a fully adjustable, independently pivoting, woofer and tweeter that enables the loudspeakers to accurately recreate high fidelity sound regardless of where they are located in the ceiling — preserving interior design integrity and delivering life-like sonic quality that is not available from conventional ceiling speakers.
Features and Benefits 3 Easy Installation The DS6.3, DS6.5 and DS6.7 employ a bracketless mounting system in existing ceilings. Simply cut a hole in the mounting surface, install the frame by tighten the four mounting “dogs” via the front panel screws. The dogs first swivel 90°, then clamp the speaker frame to the drywall as you tighten the screws. Twist & Lock Baffle Patent-pending two-piece twist and lock baffle and frame mechanism facilitates quick installations.
Recommended Amplifier Power For satisfactory performance, we recommend an amplifier with a power rating of 10 to 100 watts for the DS6.3; 10 to 150 watts for the DS6.5 and the DS6.7. 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 large amplifier will play at the same volume without distorting.
Installation Considerations Incorporating a Local Volume Control In a multiroom system there is one indispensible device for true convenience—a local volume control. It enables you to adjust the volume of the speakers without leaving the room. Plan to wire the system so that each pair of speakers has its own volume control built into the wall (think of a volume control as a dimmer switch for sound). Niles makes a wide range of high performance indoor and outdoor volume controls.
Introduction Although the DS6.3, DS6.5 and DS6.7 have extensive ability to compensate for unusual placements with their unique pivoting woofers, tweeters and acoustic finetuning switches, placement is still the primary tool for satisfying your particular listening needs. In this section, we discuss how speakers should be placed and how woofers and tweeters should be directed and how the acoustic fine-tuning switches should be set for different purposes.
Speaker Placement Placement for Varying Listening Positions If you want the freedom to sit anywhere in a room facing any direction, and/or find that you prefer the “all around you” sound of some car stereos to a conventional “sound stage” facing you, consider the speaker placement techniques professional installers use in restaurants and bars. They place speakers in an array around the listening area, so that the music is always surrounding you, regardless of the direction you face.
In large or unusually shaped rooms this might be the only way to achieve a good effect. If you like to listen to music surround modes which emulate concert hall acoustics, more than two surround speakers will prove extraordinarily effective (See Figure 6). With Niles DS6.3, DS6.5 and DS6.7 loudspeakers it is easy to add another pair without affecting the decor of the room.
Installation Fundamentals Installation Fundamentals Running the Speaker Wire in New Construction If you have doubts about whether you are capable of installing a Niles ceiling mount loudspeakers, consult a Niles dealer or professional installer. They have special tools, techniques, and experience to make the impossible possible. The installer can provide you with an estimate before any work is done. Scheduling and Preparation Plan to schedule the speaker wiring after the electrical wiring is finished.
Pulling the Cable Pull the cable in sections (from the stereo to the volume control, from the volume control to the speaker). Start with the longest sections and use left over wire to complete the short sections. If you plan to pull many rooms at the same time through a central route, walk off the distance to each destination, add a generous fudge factor for turns and other obstacles, then cut off each section so that you have a bundle of wires you can pull at once.

To find exactly where an electrical cable is routed, try inspecting the inside of the wall by turning off the breaker for a particular power outlet or switch, removing the cover plate and switch or receptacle, and shining a penlight into the wall.
Figure 10 Installation Fundamentals In traditional wood stud/drywall construction you should first cut the hole for the speaker and utilize the large hole to auger across the (through the ceiling joists) for as far as your drill bit will take you. Sometimes, you will need to use the “notching” technique to reach areas your drill bit won’t reach or to turn corners (e.g. to go down the wall when there is not an accessible attic). Don’t make an irregular hole in the drywall.
Installation in New Construction Installation in New Construction Insulating the Ceiling Cavity If feasible, fill the ceiling cavity with insulation at this point. Mounting the New Construction Bracket The hole saving bracket enables a faster and cleaner final installation of the speaker. It forces the drywall installer to cut out the speaker hole for you and provides wire ties for the speaker wire, reducing the risks of accidental loss or movement of the wire.
Figure 14 IMPORTANT: Before you cut into any wall, review the sections on running wire and speaker placement. 1. When determining the location of the speaker cutout keep in mind that the mounting dogs will extend 3/4" beyond the cutout. make sure that you do not place the edge of the cutout directly next to a ceiling joist. Locate the joists using a stud sensor or hand-knocking. 2.
Final Installation in New or Existing Construction Final Installation in New or Existing Construction 1. If it is possible to lay a batt of insulation into the ceiling cavity do so. Remember to use equal amounts of insulation for each speaker. 2. Check the position of the Impedance jumper on the crossover PC board. Choose the 4 ohm position if you are using an amplifier capable of driving a 4 ohm load and you have only one pair of speakers connected. Otherwise, use the 8 ohm position (See Figure 15). 3.
Installing the speaker 8. Holding the speaker in the palm of your hand, insert the speaker into the frame, twist clockwise to lock. (See Figure 18). 9. Direct the Tweeter. The tweeter is directed by gently pushing on the edge of the tweeter housing. (See Figure 19). It will move 17° in any direction. For critical listening point the tweeter to the user’s favorite listening position minimizing reflections from the side walls.
Operations Operation Listening at Higher Volumes It requires more power to achieve a reasonable volume of sound in a large room than it does in a small room. It is possible (even if you are not a teenager) to turn the volume so high that the amplifier runs out of power. This creates “clipping” distortion. Clipping distortion makes treble sound very harsh and unmusical.
