PLACING LOUSPEA d ERS k FOR TE h BEST SOUNd qUALITY (continued) When using more than one pair, it is usually best to alternate a left channel and then a right channel, so that you have the best possible stereo coverage possible. The position of the loudspeakers and their surroundings play a very important role in how a stereo image is created. You should experiment to find the very best position for your loudspeakers. Here are some guidelines to make the process quick and easy. Speaker Plac

You can control the loudspeaker’s bass output by placement. This is called the boundary effect. You will get more bass response by mounting the loudspeaker directly to a wall or other flat surface (any boundary close to the loudspeaker will reinforce the bass frequencies). You can increase the bass output even more by mounting the loudspeaker in a corner or under an eave (see Figure 6) This type of placement gives the loudspeaker two boundaries, thus reinforcing the bass sounds even more.

PAINTING ThE GRILLE The grille is important to the sound of the loudspeaker. Do not fill the holes of the grille with paint. The grille is constructed of aluminum with a perfectly-even powder coat overall. This powder coat is an ideal primer. If you are using a spray paint, use two thin coats without any primer. If you are using a compressor and a spray gun, use the finest, most diffuse setting. Practice on paper if you are not experienced in painting with spray paint. If you are using an ap
