Page 3: Introduction
Monolith. So, in January of 1990 we introduced the MONOLITH III to the marketplace. With the MONOLITH III, we have ad- vanced the current state of the art in Monolith III User's Manual many areas of loudspeaker design. -
Page 4: Installation In Brief
Be consistent when connecting speaker leads to the terminals on the back of the MONOLITH III: take great care to assign the same color to the (+) terminal on both the left and right channels. If bass is nonexistent and you cannot discern a tight, coherent image, reverse the (+) and (-) leads on one side to bring the system into proper polarity. -

Reflective Surfaces Reflective Surfaces your speaker system, will reflect those waves back into the room over and over again, confusing the clarity and imaging of your system. The smaller sound waves are mostly affected here and occur in the mid and high frequencies. - Page 19 Vertical Dispersion Vertical Dispersion Vertical Dispersion As you can see from the illustrations, your Monolith III speakers project a controlled dipersion pattern. Each Monolith is a four foot line source beginning two feet above floor level. This vertical dispersion profile minimizes interactions with the floor and the ceiling.
