Additional Information
Speaker layout
To obtain the best possible sound from your unit:
–Place a subwoofer wherever you like since bass sound is nondirectional. Normally place it in front of you.
–Place all the main speakers at the same distance from the listening position.
–Be sure to place the powered subwoofer to the TV’s right. If you place the powered subwoofer to the TV’s left, keep sufficient distance between them to prevent the TV from appearing mottled.
