PC board mounted bass jumper (flat, -1dB, and -2dB). 4 or 8 ohm Selectable Impedance The DS6.3, DS6.5 and DS6.7 give the installer flexibility to select the speaker’s impedance — 4 ohms for systems where maximum current transfer and output level is desired;...

Easy Installation The DS6.3, DS6.5 and DS6.7 employ a bracketless mounting system in existing ceilings. Simply cut a hole in the mount- ing 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.
For satisfactory performance, we recom- mend 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.

Speaker Wire Use 2-conductor speaker wire when con- necting DS6.3, DS6.5 and DS6.7 speakers to your receiver or amplifier. For most applications, we recommend you use 16 or 18 gauge stranded wire. For wiring runs longer than 80 feet we recommend 14 gauge stranded wire.
Speaker Placement Introduction Although the DS6.3, DS6.5 and DS6.7 have extensive ability to compensate for unusual placements with their unique piv- oting woofers, tweeters and acoustic fine- tuning switches, placement is still the pri- mary tool for satisfying your particular lis- tening needs.

“in the middle of your head” just like headphones! Systems Integration A single pair of DS6.3, DS6.5 and DS6.7 Loudspeakers, properly placed, can create a very convincing simulation of an array of speakers. If you place them near a hard reflecting surface you can make one pair of speakers sound like several.

(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. However, you will need to use...
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.

Try to line the holes up perfectly, because it makes pulling the wire much easier. A good technique is to snap a chalk line across the face of the studs or against the bottom of the ceiling joists. Then work backward so that you can always see the holes you have already drilled.

Speaker Location Figure 8 allel to power cables at least three feet away. 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, remov- ing the cover plate and switch or recepta- cle, and shining a penlight into the wall.

In traditional wood stud/drywall construc- tion 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”...
Installation in New Construction Insulating the Ceiling Cavity If feasible, fill the ceiling cavity with insu- lation at this point. Mounting the New Construction Bracket The hole saving bracket enables a faster and cleaner final installation of the speak- er. 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...
Installation in Existing Construction 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.

Figure 18 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.
Operation Listening at Higher Volumes It requires more power to achieve a reason- able 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.
