About the SI 26 and SI 28 Speakers

The Extron System INTEGRATOR™ SI 26 and SI 28 two-way

surface mount speakers are ideally suited for classrooms,

conference rooms, and boardrooms. With a weather resistant

construction, they are also suitable for outdoor environments.

• SI 26 features a 6.5" long-throw woofer, 1" tweeter, 150 watts

continuous program capacity, and frequency response from 70

Hz to 20 kHz.

• SI 28 features an 8" long-throw woofer, 1" tweeter, 180 watts

continuous program capacity, and frequency response from 50

Hz to 20 kHz.

Figure 1 — Extron SI surface speakers

NExtron recommends that the wiring installation is

performed by a professional audio equipment installer.

CUse cable clamps to hold the cables in place for

strain relief. Trim back/insulate exposed cable

shields with heat shrink to reduce the chance of short

circuits

Installation

Installing the SI 26 or SI 28 Speaker

The SI 26 or SI 28 can be mounted on a surface, such as a wall

or post, or mounted in a bookcase, or under a shelf, and can be

used with any Extron product with power amps.

Surface-mount Speakers

Figure 2 — Surface speaker application

Desk top or bookshelf applications

1. For quick installation on a desk top or bookshelf, simply

place on a desk, shelf or other ﬂat surfaces as desired.

NDo not detach the back cover.

2. Route the speaker wire (Extron recommends using

12-18 AWG) to the speakers.

3. Strip the wire and connect the speakers as described on

page 6.

Wall mounting

1. If mounting to drywall, use a stud locator to locate the

studs in the wall. Mark their position.

2. Remove the wall mount assembly from the box and

loosen the hex cap screw (by turning it counter clockwise)

with the allen hex tool supplied. Rotate the front section

approximately 90 degrees to the rear mounting plate (see

ﬁgure 3) and tighten the hex cap screw, locking the plate in

position. This will make the next steps easier to perform.

Fasten the

wall mount plate

to the vertical

surface.

Rotate This

Section 90°

Figure 3 — Rotating and mounting the wall mount

assembly

3. Mark the location of the wall mount plates three center

holes on the stud line and drill the pilot holes.

NFor some surfaces the four alternative pilot dimples

(see ﬁgure 4) may be used to secure the assembly in place.

Mark and drill as appropriate

Alternative

pilot dimples.

Figure 4 — Alternative pilot dimples on the speaker

bracket

4. Mark the wall where the wire will pass through the plate,

and cut a small access hole large enough for the wire to

pass through without snagging. If the stud is wider than

the plates access hole, then cut the hole in the wall to the

left or right and directly alongside the stud (see ﬁgure 5).

Before cutting it, make sure the plate will cover the hole

when it is ﬁnally installed.

Figure 5 — Install wall mount assembly

NExtron recommends that the wiring installation is

performed by a professional audio equipment installer.

5. Using compatible speaker wire (Extron recommends using

12-18 AWG), route the wire from the audio source to the SI

speaker location by the most convenient and safe route. If

the wiring is to remain hidden behind the wall, follow the

stud to where the small access hole has been cut, and feed

about two feet of wire out through the hole into the room.

If necessary, bend the wire to align with the plate (see

ﬁgure 5). Secure the wire at various places to the stud, but

allow enough freedom of movement near to the hole for

connection to the speaker

6. Pull sufficient wire up through the holes in the rear plate

(see figure 6) to allow ease of connection to the speaker

after installation.

Pass the wires

through the plate

access hole.

Figure 6 — Pass the wire through the plate

7. Place the wall mount assembly against the wall, aligning

the plate holes with those drilled, and secure with

appropriate hardware.

8. When the assembly is securely in place, loosen the hex

cap screw (turn counter-clockwise) and rotate the front

section back into a vertical position with the hex cap screw

at the top. Using the allen hex tool, turn the hex cap screw

clockwise to tighten.

9. Remove the cover from the back of a speaker and carefully

slide the speaker box bracket down into the V lock groove

until it locks into place (see ﬁgure 7).

Slide the speaker onto the

wall mount assembly.

10. To adjust the angle of the speaker, carefully remove the

Extron logo on the front of the speaker to expose the front

locking access (see Figure 1, Item 3, for location). Insert the

allen hex tool into the locking access, and slightly loosen

the hex cap screw. Adjust the speaker to the desired angle

(see ﬁgure 8), and torque the cap screw down clockwise

until snug. The speaker will sit securely in the desired

position. Install the Extron logo.

NThe Extron logo can be ﬁtted either horizontally or

vertically.

Turn clockwise

to tighten.

11. Repeat steps 1-10 for the second speaker.

12. When both speakers are in place, carefully pull enough

wire to reach up to the terminals at the back of the speaker

and strip the ends of the wire approximately 5/8" (15 mm),

for connection. . Twist the bared ends of each separate wire

so that they will hold ﬁrmly in the connector.

Twist the bared wire

Strip approx. 15 mm (5/8”)

Figure 9 — Strip the wire and twist the bared ends

13. Press down on the spring loaded terminals to open the

holes at the top. Observing the correct polarity, (,wire

to , terminal and .wire to . terminal) insert the

twisted wires into the relevant open holes (see ﬁgure 10)

and release the springs to secure. Push any loose wire

through the plate on the wall mount assembly and back

into the wall.

CDo not connect the speaker terminals to one

channel in parallel (together) with those of the other

channel.

Push down on the spring terminals at the

back of the speaker, and insert the wires.

Release the springs to secure.

14. Turn on the audio source and any associated devices.

Follow the manufacturers instructions to adjust the source

and device settings as desired to get the optimum audio

output for your speaker application. If necessary, re-adjust

the angle of the speaker (repeat step 10) to get the best

audio area coverage.
