Connection
NOTES:
• Pair the 8-ohm subwoofer with an amplifier that outputs up to 800 watts at
8 ohms.
• Consider the distance between the subwoofer and the amplifier and whether
doubling up the speaker cable (see
figure 12 on page 18) is necessary to
reduce the power losses through the wires.
• Avoid audio clipping:
•
Ensure that the audio source does not clip the input stage of the amplifier
(check the specifications of the amplifier)
• Ensure that the audio signal does not clip the output stage of the amplifier
(check the limiter or protection indicators on the amplifier).
•
Apply a limiter to the amplifier channel that drives the SF 10C SUB.
• No crossover is needed when the subwoofer is used with SF 26CT, SF 3C LP, or
SF 3CT LP ceiling speakers.
Configure the cable conduit access plate and captive screw connector as follows
:
1. Loosen the cable conduit access plate screw and remove the plate before wiring the

2. Configure the cable conduit access plate, using either of the following methods:
• When not using flexible conduit : Route the speaker wires through the cable
clamp (see figure 11 ,
1
, on the next page).
•
When using flexible conduit : Remove the cable clamp and install the flexible
conduit into the plate opening. Secure the flexible conduit to the plate with the
locking nut and pull the speaker wires out through the flexible conduit (
