PRO LX8 Bookshelf Speaker  
Important: Be sure you remove the  
protective packing materials before  
using the speaker (see the separate  
“Special Precautions” included with  
your speaker).  
The 8-inch driver is specially designed  
to accurately produce all sounds from  
50 to 2,200 Hz.  
The pliable diaphragm in the 2 × 4-  
inch wide-dispersion tweeter can ac-  
curately produce sounds from 2,200 to  
25,000 Hz with extraordinarily low dis-  
tortion. The tweeter’s unique design  
means there is virtually no physical  
limitation to its high-frequency sound  
production.  
The speaker cabinet is finished in  
black woodgrain vinyl. The black cloth  
grilles are acoustically transparent,  
and you can remove them for safe and  
easy cleaning.  
The LX8’s features include:  
Acoustic Design — provides broad,  
smooth frequency response.  
360° Wide-Dispersion Tweeter —  
reproduces frequencies over 20 kHz  
and uses a pliable diaphragm to re-  
duce or eliminate distortion caused by  
excess vibration.  
OPTIMUS  
Your PRO LX8 Bookshelf Speaker’s  
internal elements were exclusively de-  
signed to give you amazing music re-  
production in a small enclosure. It  
produces high sound quality with very  
low distortion, and actually delivers  
decreasing distortion as the sound  
moves to the higher frequency ranges.  
High-Compliance Woofer — accu-  
rately tracks signals to provide out-  
standing bass.
