CAUTION: REMOVE POWER
You must connect the speaker wires before the speaker is fully
installed. To protect the audio system and yourself from damage
or injury through accidental electrical shorting and surges
during installation, turn all audio system power OFF before
beginning the speaker installation.
Speaker Wire
Use high-quality speaker wire to obtain the best performance from your
Revel in-ceiling speakers.
• For wire lengths of less than 50 ft (15m), use at least 16-gauge
speaker wire.
• For wire lengths between 50 ft and 100 ft (15m – 30m), use at least
12-gauge speaker wire.
• For wire lengths of greater than 100 ft (30m), use at least 10-gauge
speaker wire.
Note: All speaker wires must comply with all local building and
safety codes for use in in-ceiling applications.
Making Connections
Connect each channel’s positive (+) terminal on the back of the amplifier
or receiver to the positive (“+”/red) terminal on the corresponding
speaker; connect each channel’s negative (–) terminal on the back of
the amplifier or receiver to the negative (“–”/black) terminal on the
corresponding speaker. Do not reverse polarities (that is, do not connect
+ to –, or – to +) when making connections. Doing so will cause poor
imaging and diminished bass response.
Negative Terminal
(“–”/Black)
Positive Terminal
(“+”/Red)
Press down on the top of the terminal to open the hole; insert the bare
end of the wire into the hole; and release the terminal to secure the wire.
CAUTION: To avoid short circuits that may damage your
equipment, be certain that positive and negative wire strands do
not touch each other and do not touch metal parts such as the
speaker frame.

For New Construction
If you wish to pre-install a rough-in frame for the speakers before the
drywall is installed in new construction, you will need to purchase
a PCK4C rough-in frame kit from your authorized Revel dealer. For
installations that require one, a fire-rated back box (model FBB4C) is
also available. Detailed instructions are supplied with the rough-in
kit and back box. After the drywall is installed, follow the installation
instructions in For Existing Construction, below.
For Existing Construction
1. Ensure that the drywall, plywood or other ceiling material is 1/2 in –
1 in (13mm – 25mm) thick and capable of withstanding the weight of
the speaker being installed.
Make sure to allow at least 1-1/2” (38mm) between the edge of the
supplied installation template and any rafters or other obstructions
behind the wall, so the speaker’s locking mechanism will have room to
engage fully. Perform an obstruction survey to be sure that there are
no studs, lengths of conduit, pipes, heating ducts or air returns in the
ceiling cavity that will interfere with the speaker.
