important installation, operation, and service instructions in this manual.
The lightning flash with arrowhead symbol within an equilateral triangle is intended to alert the user to the

Please read this manual thoroughly before attempting to install, configure, or operate the Emotiva Airmotiv 

S8 Flex Subwoofer. After successful installation and configuration of the Flex Sub, be sure to retain this 

manual in a safe place for future reference. 
Safety is a key component to a long lasting and trouble free installation. Please read and follow all 

instructions and heed all warnings on the Flex Sub and in this manual. The vast majority of the subsequent 

safety precautions are common sense. If you are not comfortable with the installation of audio/video 

entertainment equipment, you should seek the services of a qualified installation professional or call us for 

help.

on a bed, sofa, rug, or similar surface that may block vents. The unit should not be installed in an enclosed 

location such as a bookcase, cabinet, or closed equipment rack unless sufficient forced-air ventilation is

drapes that may reduce ventilation.

accessories specified by the manufacturer.
Do not install the Flex Sub on any stand, shelf, or other piece of furniture that is unable to support its 

weight. If a cart is used to move the unit, use caution to avoid injury from tip-over.
Connect the Flex Sub only to power sources of the correct voltage (as shown in this manual and on the Flex 

Sub unit). 
Protect power supply cables from being pinched, walked on, or otherwise damaged. Be especially careful 

where the power cable enters the power outlet and the unit. 
Only connect the Flex Sub to an electrical outlet or extension cord of appropriate type and rating.
