2 F ea t ur es and Benefits Intr oduction Fea tur es and Benefit s Carbon/Glass Fiber with Butyl Rubber Surround Th e CM5AT, CM6AT and CM8AT lo ud - speakers employ an advanced cone material that combines carbon and fiber glass in a special weave that maximizes stiffness and minimizes cone break up.
4 or 8 ohm Selectable Impedance The dual voice coil feature of the CM5AT, CM6AT and CM8AT gives the installer flexibility to select the speaker’s imped- ance — 4 ohms for systems where maxi- mum current transfer and output level is desired; 8 ohms for systems utilizing mul- tiple speaker pairs where amplifier loading is a consideration.
Recommended A mplifier Power For satisfactory performance, we recom- mend an amplifier with a power rating of 10 to 100 watts for the CM5AT; 10 to 125 watts for the CM6AT and 10 to 150 watts for the CM8AT. Curiously, most speakers are not damaged by large amplifiers 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).
6 Introduction Altho ugh the CM5AT, CM6AT and CM8AT have extensive ability to compensate for unusual placements with their unique piv- oting tweeters and acoustic fine-tuning switches, placement is still the primary tool for satisfying your particular listening needs.
sight with the front of the speaker . T o determine the best position, measure the “listening” distance between the ideal lis- tening position (your favorite chair or couch) and the location in which you plan to install the speakers.
array in a commercial theater. Here, it is not uncommon to see twenty or thirty speakers around the audience. This huge array of speakers assures that you will feel completely surrounded by the ambient soundtrack of the movie. Film makers try to use the “surround” soundtrack to enve- lope you in the environment on screen.

tection when drilling . Avoid nails, they ruin bits and they can create injury. Pay particu- lar care when using “hole-hogs” and other powerful electric drills; the torque of the drill when suddenly stopped by a nail can break the wrist of a strong man.
of solid masonry , and have no hollow space for speakers or wires. Start by examining all the possible routes you might take to run the speaker wire from the speaker to the volume control and back to the stere o . Use a stud sensor or other device to locate the internal struc - ture of the wall.
When you don’t have access above or below the wall, try to estimate the existing wire and pipe locations from the positions of electrical outlets and plumbed fixtures on both sides of the wall. T ake a look at the outside of your house too, sometimes conduit, vents or drain pipe will be visible that give useful information.
plenum rated wire (check your local building codes, some municipalities require conduit). 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.
Screw one side of the assembled bracket with wings to the joist using one of the supplied screws. Level the bracket. Screw the other side of the bracket/wing assem- bly to the joist. Two screws on each side make for a very secure installation. Secure the wire to the bracket using bracket’s wire tie.

If you are cutting into a plaster ceiling, use masking tape to outline your pen- ciled circle and use a razor to score the plaster down to the lath beneath.
install the speaker, first rotate the dogs inward. Insert the speaker into the cutout and tighten the dogs by turning the screws clockwise. DO NOT OVER- TIGHTEN THESE SCREWS. Over-tight- ening the clamps may make the grille difficult to install. (See Figure 17) .
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 .
