SETTING UP YOUR PRIME SPEAKERS
ROOM PLACEMENT (cont’d)
Surround Speakers
In a 5-channel system, the side surround speakers should be located 90-110
degrees off-axis. For the best sense of spaciousness, the tweeter height
should be about 2 feet above ear level.
In a 7.1 system, dedicated rear surround speakers are placed behind the
primary seating position for enhanced rear panning effects.
Place the rear surround speakers at 135-150 degrees off-axis, relative to the
primary seating position. As with the side surround speakers, position the
rear surround tweeters about 2 feet above head level when seated.
9.1 and 11.1 Systems
The recent development of 9 and 11 channel surround sound processors
brings Wide and Height ‘presence’ channels into the system to even further
enhance sound stage spaciousness and immersion.
Since native Blu-ray formats are currently only available in 7.1, the use of
Wide or Height speakers requires the use of an upconverting algorithm in the
surround sound processor - like Audyssey DSX, DTS Neo:X and Dolby
ProLogic IIz.
