3b. Rotate the speaker until the speaker box bracket left edge hooks over the left edge of the V-lock groove (see above).

3c. When the bracket is securely over the V-lock groove, gently slide the speaker down until it locks into place.

4.Repeat steps 3a to 3c for the second SI 28 speaker.

Wiring the SI 26 and 28 speakers

1.When both speakers are in place, carefully pull enough speaker wire to reach up to the terminals at the back of the each speaker and strip the ends of the wire approximately

5/8"(15 mm). Twist the bared

strands so that they hold firmly in the connector.

2. 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 13) and release the springs to secure. Push any loose wire through 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.
