A WORD FROM MATTHEW POLK
PLEASE READ THIS SECTION FIRST
Dear Music Lover,
If you intend to do the installation yourself we assume that you possess
some skill in the proper use of hand and power tools. You should have a
thorough understanding of local building and fire codes and a familiarity
with the area behind the wall or ceiling where the speakers will be
installed.
Thank you for purchasing Polk Audio speakers. Designing and building
speakers is more than just a business for the people of Polk Audio –
it is our passion. We are all dedicated to your complete satisfaction
and delight.
Wiring inside your walls or ceiling should be done before or in conjunc-
tion with installation of your in-wall speakers. Wire meeting appropriate
building and fire codes must be used. Use at least 18 gauge wire or
heavier. Wiring is best performed by a licensed professional.
Your new Polk speakers include the latest loudspeaker technology to
assure outstanding performance and unmatched quality. Please take a
moment to read through this manual for information on getting the
greatest enjoyment from these fine instruments.
We make a wide variety of main, center, rear channel, powered sub-
woofer, and accessory speakers so you can assemble a complete and
well matched high-performance surround sound system. If you would
like more information on building the Polk system of your dreams, con-
sult your Polk Audio dealer or call our Customer Service Department. In
North America call (800) 377-7655, Monday through Friday, 9:00am
through 6:00pm Eastern time.
OPTIONS
1.Your in-wall loudspeakers have been packaged with stylish metal
grilles. However, if a softer or warmer appearance is desired, white
cloth grilles are available for the AB555, AB755 and AB855 loud-
speakers. In some installations you may find cloth grilles to be less
obtrusive on the design of your living space than paintable metal
grilles. Of course cloth grilles should be used with indoor installa-
tions only.
Sincerely,
2.Outdoor all-weather grilles are available and required for outdoor
installations. Since the components and hardware used in the AB
Series of loudspeakers can withstand the elements for many years,
the purchase of outdoor grilles will allow the AB Series of loudspeak-
ers to perform reliably in outdoor installations. The AB Loudspeakers
have 1) high efficiency to insure that the higher volumes necessary
for outdoor use can be achieved with even modest amplifiers, and 2)
high power handling to insure that they will perform reliably at the
high levels dictated by outdoor use. The AB loudspeakers are truly at
home indoors as well as out.
Matthew S. Polk
Chairman and Co-Founder

4.Follow the hook-up directions included with your receiver. Strip
1/2 inch of insulation from each of the two conductors of the wire
to expose the bare metal and twist each into a single unfrayed
strand. Note that one of the terminals on the rear of each speaker
is red ( + ) and the other is black ( - ). Make certain that you con-
nect the wire from the red terminal of your amplifier to the red
terminal on your speaker and the wire from the black terminal of
the amplifier to the black terminal on your speaker. Most wire
has some indication (such as color coding, ribbing, or writing) on
one of the two conductors to help you maintain consistency.

TECHNICAL ASSISTANCE OR SERVICE
If, after following the hook-up directions, you experience difficulty,
please double check all wire connections. Make sure that your electron-
ic equipment is operating correctly by hooking up another speaker to the
speaker output. For example, if you are not getting sound from the left
channel speaker, connect the right channel speaker to the left output. If
you still get no sound from that side, the problem is in your amp, receiv-
er or source electronics. Should you isolate the problem to the speaker,
contact the authorized Polk Audio dealer where you made your pur-
chase. Authorized Polk Audio dealers are the best source for advice
and assistance.

5.After insuring that the rotating wall clamps (4 in the case of the
AB555, 6 in the case of the AB755 and 8 in the case of the AB855)
are flipped inwards, place the speaker into the cutout. If you have a
level it can help you in correctly aligning the speaker to the wall.
Tighten the mounting screws using a power screwdriver. This will
rotate the wall clamps, securing the speaker to the wall (see Fig 6).
Hint – on the AB755 and AB855 tighten the center mounting screws
before the corners for the most flush fit to the wall.
Do Not Overtighten!
6.Install the grille on the speaker. (You should have already painted
both the grille and frame.) Should you ever need to remove the
grille do not use a knife to pry between the grille and speaker
frame. Instead, insert a pointed metal tool into one of the grille per-
forations near a corner and lift the grille free.
