INSTALATION GUIDE

Rectangular In-Wall Loudspeakers
Congratulations! You have purchased a high quality
stereo loudspeaker. When matched to comparable
electronic equipment, expect years of quality high fidelity
sound. Our belief is that music matters and we are
focused on delivering superlative music reproduction
everywhere in your home.
The following manual is designed to give you, the
installer or owner, basic information as to the speaker’s
installation and operation. It is beyond the scope of this
manual to go into all the details that must be taken into
consideration in a sophisticated high fidelity system.
If you have any questions regarding this speaker which
are not answered by this manual, contact your local
dealer for assistance. For the most current information
please visit www.ditopro.com.
GENERAL DESCRIPTION
These two-way speakers have specially designed
woofers with linear long throw butyl rubber surrounds for
long life and superior damping. Dome tweeters are
utilized for excellent high frequency dispension through-
out your entire listening environment. The frame and
grille can be custom painted to match the room decor.
SHIPPING DAMAGE
Each speaker is throughly tested before it leaves the
factory. However, in shipment, accidents may occur.
Please inspect your speakers carefully when you receive
them to make sure there is no damage. If there is,
please notify your dealer or supplier inmediately for
assistance. If you received your speakers by public
transportation, report the damage inmediately to the
shipping company.
AMPLIFIER OPERATION
These speakers will perform well with amplifiers from 5
to 125 Watts RMS. However, damage to the speakers
can be done by amplifiers of nearly any power rating if
the amplifier is overdriven into clipping. “Amplifier
clipping” is a phrase used to describe a condition when,
because of the volume demand, an amplifier is being
asked for more power than it can give. Clipping cause
distortion of the audio signal. If you should hear an
unusual amount of distortion at high listening levels then
consider reducing the volume. DAMAGE TO A
SPEAKER BY CLIPPING IS NOT COVERED UNDER
THE WARRANTY.
SPEAKER PLACEMENT
Placement of Wall Mounted Speakers should be
carefully considered. Ideally, the speakers should be
located where they will provide the best possible sound
and ease of installation. It is beyond the scopre of this
publication to discuss all of the various aspects of
speaker placement. Please contact a professional for
assistance if you are uncomfortable with the planning or
installation process.
Note: Though these speakers are referred to as “wall
mount”, they are also suitable for installations in ceilings
and custom cabinetry.
WIRING
To achieve maximum performance we strongly suggest
the use of good quality stereo cable. There are many
good brands available. We recommend that the cable
be at least 16 gauge or larger for runs of over 50 feet
and that the wire be double insulated. This is often
referred to as “jacketed” speaker cable. “Zip cord”,
which is single insulated and is often made with clear
insulation, should be avoided as it is not as durable. It is
important when installing the wiring and speakers that
you adhere to all local codes and regulations. We
suggest that a professional be consulted in order to
maximize your system’s performance. The following,
however, are some useful suggestions.

Try to keep the wire length
to a minimum. However,
allow about 2½ feet of free
wire at the speaker cut-out
and sufficient length at the
electronics to aid in the
ease of installation. Adding
extra wire later is tedious
and time consuming.
Avoid bundling speaker
cables parallel to electrical
cables for extended lengths.
Though the impedance is
low and likelihood of inter-
ference low, this may help
reduce hum and RF inter-
ference. When securing
the wire, use care not to
staple or nail the electrical
conductors. Doing so could
result in a short that might
damage the electronics.
More than two pair of these speakers can be connected to one
amplifier. However, we suggest that you consult a professional if you
are installing more than two pair.
When connecting you speakers, make sure proper polarity (phasing) is
maintained. Simply put, this means being sure the same wire which is
hooked to the positive terminal of the amplifier has its other end
hooked to the positive terminal of the speaker. It is important to check
this on all speakers. If the connections on one of the speakers are
reversed, (out of phase) the quality of your bass will be seriously
impaired.
INSTALLATION
As the diagram show, the speakers utilize a metal mounting ring which,
after tightening with the screws provided, act as a clamp to hold the
speakers in place.
To aid in speaker performance, a fibrous material, such as fiberglass
or polyester fiber, may be placed behind the speaker. This may also
help to reduce unwanted sound from being transmitted into adjoining
rooms.
Once you determine where you
wish the speakers to be placed,
do the following:
Using the paper template provided,
mark the speaker cut-out location
making sure that where you wish
the speakers to be placed will not
be obstructed by a stud or other
material hidden in the wall. Proper
use of an electronic stud-finder is
invaluable for this operation. Using
the proper equipment, cut the
appopriate sized hole in the wall.

On drywall, the cleanest cuts will be made with a drywall saw.
Next, verify that the speaker fits properly into the cut-out by
passing the black mounting ring through the cut-out as illustrated.
(See figure 1) The speakers should fit comfortably in the cut-out
hole. If the hole should have been cut a little too large the flange
on the frame should cover this. Remove the speaker from the
hole.
If the wire has not yet been run, do so, now that you have access
to the wall´s interior. Once the speaker wire has been run, pull the
end of the wire out of the wall, strip back a section of the jacket as
needed, and then expose ½" of each conductor. Connect the wire to
the terminals on the back of the speaker assembly, observing polarity
(+ & -).
Install the speaker in the wall and gently tighten all of the screws so
that the mounting ring clamps against the back side of the wall board.
(See figure 2) If your speaker has six screws begin with the middle
pair. Avoid over-tightening the screws or it may later become difficult to
install the grille.
Install the grilles after testing the operation of the speakers. The grilles
are installedd by gently working the edge of the grille into the frame of
the speaker beginning at one corner and working one or both
directions around to an adjacent or opposite corner.
