19 Specifications CM8HD Driver Compliment 8" injection-molded TCC (talc, carbon and ceramic filled) with rubber surround 1" fluid-cooled ultra-wide dispersion tri-laminate Teteron tweeter in.
Recommended A mplifier Power For satisfactory performance, we recom- mend an amplifier with a power rating of 10 to 100 watts for the CM5HD; 10 to 125 watts for the CM6HD and 10 to 150 watts for the CM8HD. Curiously, most speakers are not damaged by large ampli- fiers but by small amplifiers.
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 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 con- trol as a dimmer switch for sound).
18 Specifications Specifications CM5HD Driver Compliment 5-1/4" injection-molded TCC (talc, carbon and ceramic filled) with rubber surround 1" fluid-cooled ultra-wide dispersion tri-laminate.
17 Oper a tions Oper ation 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.
6 Although the CM5HD, CM6HD and CM8HD have extensive ability to compen- sate for unusual placements with their unique pivoting tweeters and acoustic fine- tuning switches; placement is still the pri- mary tool for satisfying your particular lis- tening needs.
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 profession- al installers use in restaurants and bars.
9. Setting the Bass and Treble cut switch- es. Listen to a well-recorded piece of music at the user’s favorite listening position. a) Listen for bass boominess, particularly when the speaker is placed ne ar a c orn er . Use the -2dB Bass cut to correct.
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 speaker. 2 . Check the position of the Impedance Jumper on the crossover PC board.
However, as you move the speaker far- ther away from the listener, both the reflected and the direct sound will dissi- pate, requiring more power from your surround sound amplifier channels.
Inst allation Fundamen tals 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.
Inst allation in Existing Constr uction 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.
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 speak- er.
of your contractor. 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.
allel 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, 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” technique to reach areas your drill bit won’t reach or to turn corners (e.
