[. . . ] An out-of-phase pair of speakers work against each other and the sound of the two speakers playing together will be lacking in bass and be "phasey" sounding. If you suspect the sound is not right and you cannot see any markings on the wire, try this simple test: 1. Play some music with the amplifier or radio set to Mono. Listen to the richness of the bass and the loudness of the sound. Turn off the amplifier and reverse the connections on one amplifier channel only. Repeat the listening test with the same setting of the volume control. When the sound has a richer bass and is slightly louder the speakers are working together or "in-phase".

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 near a corner. b) Listen for treble harshness or ringing, particularly when the speakers are placed in a room without carpet/ Use the -2dB Treble cut switch to correct. If you have difficulty fitting them in, try loosening the mounting dog screws (excessive tightening can distort the shape of the frame holding the grille in place). Painting the Speakers All models may be painted. The plastic will readily accept most paints. The speakers must be masked prior to painting them. The inside circular portion of the hole template can be used as a paint mask. Remove the outside portion of the template by gently pulling along the perforation. Affix the mask to the front of the speaker using a piece of tape. Fold the tape onto itself to form a double-sided loop. Affix the tape to the tweeter and place the mask onto the speaker. The grilles should be painted before they are installed. For all models, the best 16 Final Installation in New or Existing Construction 1. [. . . ] In some areas of the country the exterior walls are constructed 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 stereo. Use a stud sensor or other device to locate the internal structure of the wall. A typical route would be: from the speaker location in the ceiling, across the attic, then down through a top plate (the horizontal 2x4 or 2x6 laid across the vertical studs) to the volume control location, back up to the attic, across the attic, and finally down another wall plate to a J-Box in the wall behind the stereo system itself (See Figure 8).
