Page3 Monolith III User's Manual Introduction Congratulations, you have invested in one of the world’s premier loudspeaker systems! The Martin-Logan MONOLITH III repre- sents the culmination of an intensive, dedicated group research program directed toward establishing a world class reference monitor utilizing leading-edge technology, withou[...]

Page4 Monolith III User's Manual We know you are eager to hear your new MONOLITH III loudspeak- ers, so this section is provided to allow fast and easy set up. Once you have them operational, please take the time to read, in depth, the rest of the information in this manual. It will give you perspective on how to obtain the best possible perfo[...]

Page5 Monolith III User's Manual Monolith III Specifications The MONOLITH III hybrid speaker system consists of a broad-range single element electrostatic transducer integrated with a quick-response woofer. This approach takes maximum advantage of the positive aspects that both technologies have to offer. Dispersion is a controlled 30 degrees.[...]

Page6 Monolith III User's Manual In the late 1800’s, any loudspeaker was considered exotic. Today, most of us take the wonders of sound reproduction for granted. It was 1880 before Thomas Edison had invented the first phonograph. This was a horn-loaded diaphragm that was excited by a playback stylus. In 1898, Sir Oliver Lodge invented a cone[...]

Page7 Monolith III User's Manual extremely accurate speaker, but Janszen found that the cone speakers of the period were too nonlinear in phase and amplitude response to meet his criteria. Janszen believed that electrostats were inherently more linear than cones, so he built a model using a thin plastic diaphragm treated with a conductive coat[...]

As such, they must be connected to an AC wall outlet. For this reason we have provi[...]

Page17 Monolith III User's Manual To prevent subsonic energy from taxing the listener, room, and driver, a sub- sonic high-pass filter is necessary. A third filter is reserved for low-pass filter operation. The characteristics of frequency and “Q” of each filter is affected by component value selection within each filter section. The woofe[...]

Since the diaphragm of an electrostatic speaker is uniformly driven over its entire area, it can be extremely light and flexible. This allows it to be very responsive to transients, thus perf[...]
