The Leader in High-Performance Loudspeakers®
Thank You
Thank you for choosing the Definitive Technology Disappearing In-Wall loud
speaker. The
Di Series products offer extraordinary sound quality from speakers that
are barely visible when installed in awall or ceiling. Our engineers spent many
years developing this product. In order to ensure that you experience the finest per
formance possible, we encourage you
to take a moment to fully read this owner's
manual and familiarize yourself with the proper installation
and set-up procedures
for your
Di Series speaker.
Unpacking Your Disappearing In-Wall Speakers
Please Inspect For Shipping Damage
Each loudspeaker leaves our plant in perfect condition. Any visible or concealed
damage most likely occurred in handling after it left our plant
and should be reported
at once to your Definitive dealer or
the delivery company that delivered your loud-
speaker. Please unpack your system carefully. Save all cartons
and packing materials
in case you move or need to ship your system. Record the serial number found on
the back of the speakers, and on the carton, in this manual and save it for future
reference should your speaker need service. For your best protection, register your
Di Series products on-line at http://registration.definitivetech.com.

Painting Di Series Speakers
Your Di Series speakers may be painted to match the color of the wall
or ceiling in which they are installed. Failure
to follow the following
painting instructions may result in seriously degraded sound quality.
It is your responsibility to make sure your painting contractor sees and
follows these instructions.
1. DO NOT PAINr THE GRILLE WITH A BRUSH OR ROllER -
they will
dog the fine mesh of the grille and doth scrim and result
in poor sound quality.
2. Remove the grille from the speaker and place it on adrop doth,
newspaper or plastic sheet.
3. The grille MUST be spray painted with one ofthe following:
•Spray paint
that closely matches the desired finish/color
• A custom spray bomb, color matched to your paint finish
•Indoor latex paint using aspray gun (paint must be diluted
to the paint manufacturer's specifications)
4. Removing the backing doth (scrim) is not required.
S. Paint should be applied in aseries of thin coats sprayed at
approximately 60 degrees from
the grille surface, allowing each
coat
to fully cure before applying additional coats.
6. To ensure that the paint distribution is evenly applied, each coat
should be applied from at least 4different directions
to the grille.
(N, S, E&W) This will ensure an even coverage on the grille.
7. Once the grille has been painted and the paint has fully cured, you
may use abrush, or small roller
to touch-up the outer edge of the
grille frame -being VERY careful not to get any additional paint
on the grille mesh surface.
Optional Fire-Rated Enclosures
Definitive Di Series speakers have been designed to meet UL 1480 and
2043 standards when used with the appropriate optional Definitive
fire-rated enclosures.
All plastic parts used in the speakers are VO flame
rated as per
UL 94.
While these enclosures are necessary in most countries for commerdal
and multi-family dwelling installations, residential customers may want
to use them for added safety and/or to reduce the sound from "leaking"
into adjacent rooms.
Recommended speaker
distance from side walls
is 2 feet (60cm).

Placement Options o o
Definitive Technology Di Series Loudspeakers give you nearly endless
placement options. But remember
that placement choice for your in-wall
speakers bears careful consideration,
as installation requires that you cut a
hole in your wall or ceiling!
Fill aroom with sound by installing in-wall
speakers in nearly any wall or ceiling location although it
is best to keep
the speakers at least 2feet (60 em) from side walls [Figure 1]. When using
Di Series models in home theater applications follow the guidelines
[illustrated
in Figures 2,3 and 4]. Definitive Di Series In-Wall Loudspeakers
have aimable tweeters
that allow you to focus their sound toward or
away from your listening area depending
on the application.

Figure 6b
Aiming the Tweeter
Atweeter aimed toward your listening position improves imaging and
detail.
To aim the tweeter, first install the speaker in the desired location.
Rotate the tweeter
so that the arrow on the tweeter faceplate is pointing
in the direction you wish to aim the tweeter
[Figure 5] then gently push
the tweeter in
that direction [Figure 6]. When using Di Series In-Wall
Loudspeakers
as front/main home theater speakers or as stereo speakers
in adistributed audio system aim the tweeter toward
the main listening
position.
For rear/surround speakers installed in walls or ceilings, aim
the tweeter toward the nearest reflecting surface (an adjacent wall or
ceiling)
for amore diffuse sound field (if you so desire; for more direct
sound, aim
the tweeters at your listening position).
Environmental EQ·
(not included on Di 3.5R and Di 4.5R models)
If your listening room is very reflective, with smooth sheetrock walls,
hardwood floors,
and non-cushioned furniture, the sound will be overly
"bright"
and unnatural. Engaging the Environmental EQ feature
[Figure 7] (by selecting the "-" setting) compensates for the effect of
overly loud treble.
If your room is has alot of absorbing surfaces such as
over-stuffed furniture, heavy drapes
and rugs such that the speakers
sound "dull," engage
the "+" setting to boost treble response. Leave the
switch in the center position in rooms with abalance of reflecting and
absorbing surfaces (most rooms fall into this category). Note: the Di 6.5STR
has atwo position switch; the minus symbol "." represents normal treble
output
and the plus symbol "+" represents treble boost.

Installation
Installation Cautions
Installation of Disappearing Series Loudspeakers requires skills in
using tools such
as adrill, screwdriver, saws and power tools. Installation
also entails running wires through walls.
You should have athorough
understanding of local building
and fire codes and afamiliarity with
the area behind the wall or ceiling into which
you plan to install
your speakers.
When cutting holes in and running wires through walls/ceilings you run
the risk of cutting electrical wires
or water pipes thereby causing safety
hazards and property damage. If you are in
any doubt that you possess
the necessary skills or tools, contact your Definitive Technology dealer,
general contractor or aprofessional installer.
Required Tools
•Pencil for marking the location of installation.
•Bubble level (for
Di 5.5S and Di 6.5S models only)
•Keyhole
saw, utility knife or material- appropriate incising
implement
for cutting drywall or other wall material.
•Phillips head screwdriver.
•Power drill with appropriate bit (optional, for starting wall cut).
Installation Procedure
• You must first install speaker wires that meet appropriate building and
fire codes before installing the speakers. Use at least 18 gauge wire or
heavier to ensure optimum sound quality.

Left channel wires
Figure 12
Figure llb
•Once you have cut the hole, pull the speaker wire
out of
the hole and connect the speaker. Strip '/z"
inch (12 mrn) of insulation from each ofthe two
conductors of the wire to expose the bare metal
.
and twist each of the conductors into asingle
unfrayed strand. Note that one of
the terminals
on the rear of each speaker is marked red (+) and
the other black (-). Make certain that you connect
the wire from the red terminal (+) of your amplifi-
er or receiver to the
red terminal (+) on your
speaker
and the wire from the black terminal (-)
of your amplifier or receiver to the black terminal
(-) on your speaker. Most wire has some indicator
(such
as color-coding, ribbing or writing) on one
of the two conductors to help you maintain
consistency
[Figure lla). In the case of the Oi
6.SSTR single speaker stereo model, both left
and right channel speaker wires are connected
to the speaker [Figure llb) ..
•Push down on the top of the terminal to reveal
the wire hole in the side of the terminal post and
insert the wire into the hole
[Figure 12]. Release
the pressure on the terminal to secure the wire.
•Loosen the rotating lock arms by turning the lock
arm screws
on the front of the speaker counter
clockwise
Ji to 1tum, just enough to allow the lock
arm to move
freely. [Figure 13). Make sure that the
rotating lock arms are flipped inwards
[Figure 14)
so that your speaker fits into your cutout.

Figure 10
Template

•Make sure the material into which you plan to mount the speakers
(plaster, drywall, paneling, stone, etc.) can support the weight of
the speakers
(see spedfication page for the weight ofyour model).
•Make sure the locations you select do not conceal studs, electrical
wiring or plumbing. Prior
to installation, hold the speaker with
grille
on in your chosen
location to make sure it safely
clears obstacles such
as studs,
comers, beams, lighting
fixtures
and door/window
frames.
Your cutout must
be at least
2" (50 mrn) from
adjoining walls or ceiling,
internal studs or plumbing.
•Using the supplied template,
trace the installation location
with apencil.
You can do
this by holding the template
in your preferred location
and tracing around it. In the
case of the rectangular
models (Di 5.5S
and Di 6.5S)
use abubble level to square
and level the template.
[Figures 8& 9]
•Carefully cut the hole
with the appropriate cutting
tool for your wall or ceiling
material. Start the hole by
drilling ahole
on the inside
of the tracing (with the drill
bit just inside the line). Use
this hole to insert the saw
or knife
and begin cutting
[Figure 10). The holes for the
Oi 3.5R and Oi4.SR must be
cut very precisely as their
flanges are only
3/
8
"
(9.5 mm)
wide.
We recommend using
hole saws to cut the holes
for these models - 33 /." for
the Di 3.SR and a 4'/z" for
the Oi 4.SR.

•Place the speaker carefully into the cutout. If you have alevel, use it
to help you correctly align rectangular speaker models. Tighten the
lock arm screws with ascrewdriver [Figure 15). TIJ.is will rotate the
lock arms [Figure 16] and secure the speaker to the wall/ceiling.
