!
Ensure your receiver or multichannel amplifier is switched off before connecting speakers
Before powering the subwoofer make sure the local operating voltage is the same as that specified for your unit
Turn subwoofer off before connecting the input cable
Be sure to connect plus (+) and minus (-) terminals of the speakers' binding posts to the corresponding plus (+)
and minus (-) terminals of the receiver or multichannel amplifier
Make sure that all connections are secure, especially if using bare speaker wires
Contact between stray bare wires between plus (+) and minus (-) terminals may cause a damaging short-circuit
Avoid using equalizers that may add distortion
Your THX Select Certified speakers are built to tightly controlled tolerances and specifications so dispersion
and frequency response are optimized by design, even at high output levels
There is risk of damaging your speaker drivers with low-power amplifiers operating at or near their power limits
Clipping can destroy individual drivers, usually the tweeter
That's why all Crystal Acoustics speakers feature Electronic Tweeter Protection
Receivers and multichannel power amplifiers of at least 80 WRMS are recommended
Do not drive speakers with continuous power exceeding the maximum indicated in the instruction manual
for each speaker model (See Specifications Section 6.)
Use the best quality speaker cables and interconnect possible
Connect speakers cables to the upper pair of binding posts when single-wiring and let the jumper links take
the signal to the lower frequency drivers
Do not place loudspeakers in dusty or humid environments
Avoid exposure to direct sunlight
