•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 specification page for the weight of your 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, corners, beams, lighting fixtures and door/window

frames. Your cutout must	Template

•Using the supplied template, trace the installation location with a pencil. 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 a bubble 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 a hole 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 Di 3.5R and Di4.5R 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 — 33/4" for the Di 3.5R and a 41/2" for the Di 4.5R.

• Once you have cut the hole, pull the speaker wire out of the hole and connect the speaker. Strip 1/2" inch (12 mm) of insulation from each of the two conductors of the wire to expose the bare metal and twist each of the conductors into a single 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 11a]. In the case of the Di 6.5STR single speaker stereo model, both left and right channel speaker wires are connected to the speaker [Figure 11b].

•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 12⁄ to 1 turn, 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.
