Easy Installation The DS8.3 and DS8.5 employ a bracket- less mounting system in existing ceilings. Simply cut a hole in the mounting surface, install the frame by tightening the four mounting “dogs” via the front panel screws. The dogs first swivel 90°, then clamp the lo udsp eak ers frame to the dry- wall as you tighten the screws. Twist &[...]

Recommended A mplifier Power For satisfactory performance, we recom- mend an amplifier with a power rating of 10 to 150 watts for the DS8.3; 10 to 175 watts for the DS8.5. 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[...]

Incorporating a Local Volume Control In a multiroom system there is one indis- pensible device for true convenience — a local volume control. It enables you to adjust the volume of the lo udsp eak ers without leaving the room. Plan to wire the system so that each pair of lo udsp eak ers has its own volume con- trol built into the wall (think of a[...]

more “surround sound” effect. However, as you move the loudspeaker farther away from the listener, both the reflected and the direct sound will dissipate, requiring more power from your surround sound amplifier channels. If the surround sound system you are using has a small five or ten watt amplifier for the rear loudspeak- ers, stay within fi[...]

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 spe[...]

6 Introduction Although the DS8.3 and DS8.5 have extensive ability to compensate for unusual placements with their unique pivoting woofers, tweeters and acoustic fine-tuning switches, placement is still the primary tool for satisfying your particular listening needs. In this section, we discuss how loudspeakers should be placed and how woofers and [...]

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. Paying careful attention to this will save you a lot of time later on![...]

beside electrical wire for more than a few feet. T ry to keep speaker wire running parallel to power cables at least three feet away. T o 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, [...]

In traditional wood stud / drywall construc- tion you should first cut the hole for the loudspeaker 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. [...]

Inst allation in Ne w Constr uction 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 lou d- spe ake r. It forces the drywall installer to cut out the loudspeaker hole for you and pr[...]

Inst allation in Existing Constr uction IMPORTANT: Before you cut into any wall, review the sections on running wire and loudspeaker placement. 1. When determining the location of the loudspeaker 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 t[...]

Final Ins talla tion in Ne w or Existing Constr uction 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 loudspeaker. 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 [...]

the user’s favorite listening position minimizing reflections from the side walls. For surround sound or low volume background listening create more reflections and thus more ambi- ence by directing the tweeter towards the side walls. 8. Direct the Woofer. The woofer is direct - ed by gently pushing on the outer edge of the grille face. (See Figu[...]
