Safety Instructions
• Please read the instructions carefully before installation and use. Keep the manual safe for future reference.
• Prior to installing the speakers into any ceiling/wall, check the structure for weight bearing ability and avoid contact with any
wiring or plumbing that might be behind the surface area. Installing on soft materials or in areas incapable of supporting the
speakers’ weight may cause personal injury or damage to the speaker.
• Make sure the speaker is properly secured to the ceiling/wall. Please use the proper screws, bolts, or anchors. Failure to do
so may cause the speaker to become unsecured and cause potential damages/injuries.
• Damage to the woofer and tweeter may occur if the speaker is dropped or hit-resulting in no sound or distorted sound.
• Never overdrive your speakers to the point of distortion and always reduce volume prior to switching input sources.
• Use only approved and certied wiring in your installation, do not stretch or place the wire in contact with sharp objects.
• Prior to removing cables ensure all power to your amplier and other components is turned o󰀨.

Installation
1. Cut the Speaker Hole
Use a stud nder to locate an area that is free of obstructions or studs. Position the cutout template where you are installing
the speaker. Trace the template to mark out the speaker location with a pencil. Drill a pilot hole and cut all of the way around
the circular outline with a cutting saw.
2. Wire the Speaker
Pull the speaker wire out of the hole which you have cut and connect it to the speaker as shown.
3. Install the Speaker
Place the speaker into the ceiling and tighten all the clamp screws with a Philips screwdriver.
4. Attach the Grill
As several magnets are on the speaker frame, attach the grill to the rim of the speaker directly. Ensure the grill is attached to
the speaker securely to keep the grill from falling.
Connection
Ensure that the speaker is unplugged from the mains before making any connections.
Stereo Connection of L/R Pair Speaker
Connect the input terminals of the speakers to the speaker output terminals of the amplier. Always check to ensure polarity
is correct:
L(left) to L, R(right) to R, “+” to “+”, and “-” to “-”.

Note: Anytime you note distortion, reduce the volume to a lower setting. Never allow your amplier to be driven into “clipping”.
Otherwise the speakers may be damaged. Damage caused by operating the speakers at distorted volume levels is not cov-
ered by the warranty.
Care and Maintenance
• Turn o󰀨 the power to the speaker when unused for long periods of time.
• Ensure all equipment is turned o󰀨 prior to cleaning. Surfaces need only occasional dusting/cleaning. Never use chemicals
or solvents as they may damage the surface. Always clean using a dry cloth.
• Never touch the speaker drivers.
