introduction
Thank you for purchasing an a/d/s/ L series mini-speaker system. The L210 and L310 are the latest
descendants of the original ADS mini-speaker which first introduced the concept of big sound from a
small box. The L210 and L310 produce superior sound with classic a/d/s/ drivers and advanced crossover
technology. The sonic realism, bass response, and output capabilities are remarkable for such compact
loudspeakers. The L210 and L310 are magnetically shielded and are supplied with mounting brackets.
This edition of a/d/s/ mini-speakers features new cast aluminum housings that are weather resistant,
allowing the L210 and the L310 to be permanently mounted outdoors. In addition, the L210 and L310
drivers are magnetically shielded so that they may be used indoors near television screens or computer
monitors. The L series mini-speaker systems will not only provide excellent performance when used
alone, but may also be combined with an a/d/s/ powered subwoofer to provide stunning full range high
output Audio/Video system performance. Clearly the L210 and L310 are two of the most versatile
speakers available. Any type of system, ranging from outdoor applications, to home theater systems,
to multimedia computers can take advantage of their exceptional performance.
Installing the L210 or L310 is not difficult. However, correct wiring and proper placement play a vital
role in optimizing sound quality. This manual provides information on the placement, connection and
operation of your loudspeakers. Please read it thoroughly and save it for future reference.
speaker placement
Where speakers are placed significantly affects their sound. Some general placement guidelines are
given below. However, since all situations are different you should experiment with various locations
to determine where they sound best.
Outdoor use
Although the L210 and L310 are “all weather” loudspeakers, when using them outdoors you will
extend their life and improve reliability if you avoid mounting them where they will be exposed to
direct sunlight for extended periods of time. The L210 and L310 will stand up to moderate amounts of
moisture. However, they should not be mounted will be directly exposed to heavy rain. In colder
climates, bringing your loudspeakers inside for the winter when they are not being used is advised.
Boundaries
In general, the L210 and L310 will produce the smoothest response and best stereo image when located
at least two feet from the room boundaries - that is, the floor, ceiling and walls. Moving the speaker
closer to one or more boundaries will increase the bass output. In some rooms, the extra bass will
enhance the sound. In others the extra bass will be too much, making the sound “boomy” or “tubby”.
Experimenting with speaker placement is the most important thing you can do to achieve the best
possible sound.
“Hard” surfaces near a speaker can affect the distribution of high frequency sound in the room. As a
result, the accuracy of the stereo image. If the speakers are near the corners, point the speakers
towards the center of the room. If the floor in front of the speakers is not carpeted, place a small area
rug in front of the speaker to reduce high frequency reflections and improve the stereo image. When
a speaker is on a shelf or tabletop, keep the front of the speaker flush with the edge of the supporting
surface if possible.
