Surround Back
In addition to the left and right surrounds, THX Ultra2 7.1-channel system specifications call
for two forward-radiating surround back loudspeakers behind the listening area, preferably
spaced no more than a few feet apart. These would be KL-650-THX or KL-525-THX LCR’s,

channels due to their smaller size. Their WDST design works very well in this application.

however and in many installations a single KW-120-THX will be completely adequate.
Although the KW-120-THX will perform well in a wide variety of locations, you will get the
most out of it by following some simple guidelines:

wall.
• In most rooms, a subwoofer will deliver smoothest bass response when placed in a
corner away from room openings, such as doors. So if possible, that’s the place to start.
• If you are using more than one subwoofer you usuall
placing them together in the same location rather than by spacing them apart.
Naturally there are exceptions to the general rules, since no two rooms or systems are
exactly alike. Once you have the subwoofer connected to your system and adjusted at
least roughly (see the KA-1000-THX manual for details), you may want to experiment to
see if you can do better

mum, we recommend that you use 16-gauge or heavier stranded copper wire. Use lower
gauge (heavier) wire for long runs to maintain correct frequency response and minimize
power loss.
On the back of each KL-650-THX, KL-525-THX and KS-525-THX speaker are two sets of
binding posts, one feeding the tweeter and the other the woofers. For conventional wiring,
these sets are connected together with gold-plated metal straps, which can be removed for
bi-wiring or biamping. We will explain ordinary single-wiring first and then the alternatives.
All the information regarding single-wiring also applies to bi-wiring.

Pull the two conductors apart for about an inch and strip approximately 1/4-inch
of insulation from the end of each. (A wire stripper will simplify this, but you can use an
ordinary pocket knife to cut around and through the insulation down to the wire.) T

Many pre-made speaker cables are terminated with metal pins. Loosen the nuts on a
pair of binding posts until the holes through the metal posts are exposed, then insert the
pins through the holes. Screw the nuts down finger-tight on the pins — do not overtighten.
KW-120-THX will be completely adequate. The companion KA-1000-THX subwoofer amplifier
can drive either one or two subwoofers. In dual-subwoofer systems, it is usually best to place
them right next to each other rather than spaced apart.
Normally the array would be either all KL-650-THXs or all KL-525-THXs, but the center
speaker can be different from the left and right speakers. (For example, you might combine a
pair of KL-650-THXs for the front left and right with a KL-525-THX for the center
ter-channel speaker should be centered along the width of the

left and right speakers should be placed equal distances out from the edges of the TV screen.
Exactly how far out depends on the size of the screen. A reasonable starting point is to place
the left and right speakers so that they and your listening position form an equilateral triangle.
Since the center speaker helps anchor the sound to the screen, it usually is better to have the
left and right speakers spread a little too wide than to have them too close together The left
and right speakers should be aimed inward towards the listening position as shown in figure
