In-Ceiling Speakers

Introduction
Congratulations and thank you for purchasing
Knoll in-ceiling speakers. When installed
correctly, these speakers will give years of
enjoyment. Their very flat grill and frame design
will appeal to the most critical eye. The SD652
has two speakers in one chassis for single point
stereo. This is ideal for hallways and other places
that are not suitable for separate stereo
speakers. To obtain the full potential of your new
speakers, please read all instructions before
starting the installation. If you do not have the
necessary skills to install the speakers yourself,
contact your Authorized Knoll Dealer for
installation options.

You'll appreciate Knoll's speakers as they provide top-
of-the line performance and enjoyment value especially
when installed by skilled professionals. Custom
installers can help design the system you've been
looking for by coordinating their efforts with
architects, interior designers, and electricians to
ensure perfect engineering and performance in your
home theater.
In the capable hands of a custom installer, special
devices like those supplied by Knoll can make the most
sophisticated audio/video systems easy-to-use and
practically invisible.

Speaker Placement

The location of the speakers should be determined by
considering your primary listening location and
aesthetic values. For best results, contact your
Authorized Knoll Dealer for advice.
Distributed Audio Placement
Round speakers are able to perform in any orientation
(horizontally or vertically) without effect to the sound
presence of the source signal. The hemispherical
dispersion pattern allows the installer and user to
configure the speaker in any position without
performance penalty. Locate the speakers above the
primary listening area and angle the tweeter(s) toward
the listening area. If there are "hot spots" in the
room, consider adding additional speakers for more
uniform sound dispersion.
Surround Speaker Placement
Your Knoll speakers can be used as surround and front
speakers in your home theater. Surround speakers can
be located in the ceiling of your home theater. The
proper placement of surround speakers is very room
dependent. If you are unsure about where to locate
your surround speakers for best performance, contact
your Knoll Dealer for advice.
When mounting your surround speakers in the ceiling,
locate the speakers 2 to 6 feet behind your listening
position. The speakers should be separated anywhere
from 6 to 10 feet apart center to center. Adjust the
level controls on your receiver or processor so that all
the speakers produce the same SPL reading.
Wire Sizes
We always advise using fire-rated speaker wire when
installing wires inside the wall (check with local
authorities). As a general rule, the wire cable
impedance should never be more than 10 percent of
the speaker impedance. For runs less than 50 feet use
minimum size 18-gauge wire. For runs 50 to 100 feet
use minimum size 16-gauge wire. For longer size runs
use 12 or 14 gauge wire.
In general the larger wire size used will result in
better sound quality. While using insufficient gauge
wire may be acceptable to some people, the resulting
sound will be less dynamic than if better, larger cable
(smaller gauge numbers) is used.
