Surround Back Speakers
With the advent of Surround EX, you now have the ability to create an even more realistic soundstage
by adding one or two surround back speakers that should be located behind the listening position. As
with the surround speakers, the surround channels aren’t meant to be localized but to substantially add
to the envelopment of the surround sound experience. This additional channel can be either discrete or
matrixed depending on the source material. Although most media encoded in Surround EX or EX has
a single Surround Back channel, there is some material can be encoded with up to two discrete surround
back channels.
Subwoofer
Because of their long wavelengths, low bass frequencies are critically dependent on room placement to
avoid bass-robbing standing waves or null points. Sometimes moving a subwoofer a few inches makes
the difference between thin, weak bass and room shaking, foundation-rattling bass. One of the most
reliable methods to correctly position your subwoofer is to first hook it up and place it next to your
favorite listening position. While it is playing music or a movie with strong bass in it, slowly walk
around the various room locations where the sub could be located. You should be able to find a place
where you hear balanced bass without excessive boominess. Once you have found this optimum location,
simply move the subwoofer there. If you change your listening position, you should repeat this procedure.
If you are unable to place the sub where it sounds best, you might improve its sound by turning the
sub’s cabinet to one side or the other. The Suite 7.1 has two subwoofer outputs, in case you prefer two
smaller subs in place of one large sub, or if you have an insatiable (but certainly understandable) desire
for intense bass. However note that positioning two subs for ideal response is more challenging than
positioning one, because they will interact with each other as well as with your room.
