PRO LX7 Bookshelf Speaker  
produces high sound quality with very  
low distortion, and actually delivers de-  
creasing distortion as the sound  
moves to the higher frequency ranges.  
Its features include:  
Optimus True Line Source Driver  
uses a pliable diaphragm to reduce or  
eliminate distortion caused by excess  
vibration. It also can reproduce higher  
frequencies (over 20 kHz) without be-  
ing limited by its physical construction.  
OPTIMUS  
Your PRO LX7 Bookshelf Speaker’s  
internal elements were exclusively de-  
signed to maintain shape through all  
phases of operation, move diaphragm  
elements with efficient speed, and  
faithfully reproduce high frequencies.  
— accu-  
High-Compliance Woofer  
rately tracks signals to provide out-  
standing bass.  
The 7-inch driver is specially designed  
to accurately produce all sonic infor-  
mation from 45 Hz to 2 kHz. The pli-  
— provides broad,  
smooth frequency response.  
Acoustic Design  
1
able diaphragm in the 3-inch ¥ 3 /2-inch  
driver can accurately produce sonic in-  
formation from 2 kHz to 25 kHz with  
extraordinarily low distortion. The  
tweeter’s unique design means there  
is virtually no physical limitation to its  
production of high-frequency sound.  
SPEAKER PLACEMENT  
For the best stereo image, place a pair  
of speakers so the distance between  
them is about the same as the distance  
between the listening area and the  
point halfway between the speakers.  
The speaker cabinet is finished in  
black woodgrain vinyl. The black cloth  
grille is acoustically transparent, and  
you can remove it for safe and easy  
cleaning.  
If you must place the speakers farther  
apart, turn them slightly inward. If you  
must place them closer to each other,  
turn them slightly outward. Experiment  
with your speakers’ placement to dis-  
cover the best location for them.  
This speaker gives you amazing music  
reproduction in a small enclosure. It

CARE AND MAINTENANCE  
Your Optimus PRO LX7 Bookshelf Speaker is an example of superior design and  
craftsmanship. The following suggestions will help you care for your speaker so you  
can enjoy it for years.  
Keep the speaker dry. If it gets wet, wipe it dry immediately. Liquids  
might contain minerals that can corrode the electronic circuits.  
Use and store the speaker only in normal temperature environments.  
Temperature extremes can shorten the life of electronic devices and  
distort or melt plastic parts.  
Keep the speaker away from dust and dirt, which can cause prema-  
ture wear of parts.  
Handle the speaker gently and carefully. Dropping it can damage cir-  
cuit boards and cases and can cause the speaker to work improperly.  
Wipe the speaker with a damp cloth occasionally to keep it looking  
CLEANER  
new. Do not use harsh chemicals, cleaning solvents, or strong deter-  
gents to clean the speaker.  
Caution: You might permanently damage your speaker by cleaning it with a vacuum  
cleaner. Instead, use a feather duster or a soft cloth.  
Modifying or tampering with the speaker’s internal components can cause a mal-  
function and might invalidate your speaker’s warranty. If your speaker is not per-  
forming as it should, take it to your local Radio Shack store for assistance.
