Mounting the Speakers
The speakers can easily be wall mounted by using the 
keyhole slots. To prevent the speaker from vibrating 
against the wall, attach four of the supplied spacers to the 
keyhole fins on the rear of each speaker.
To mount the front or surround speakers vertically, use 
the keyhole slot shown to hang each speaker on a screw 
that’s securely screwed into the wall.

Surround speaker (SKM-330XS)
To mount the center speaker horizontally, use the two 
keyhole slots shown to hang each speaker on two screws 
that are securely screwed into the wall.

Caution:
A mounting screw’s ability to support a speaker depends 
on how well it’s anchored to the wall. If you have hollow 
walls, screw each mounting screw into a stud. If there are 
no studs, or the walls are solid, use suitable wall anchors.
Use screws with a head diameter of 9 mm or less and a 
shank diameter of 4 mm or less. With hollow walls, use 
a cable/pipe detector to check for any power cables or 
water pipes before making any holes.
Leave a gap of between 7 mm and 10 mm between the 
wall and the base of the screw head, as shown.
(We recommend that you consult a home installation 
professional.)
Threaded inserts for machine screws are provided on the 
rear of each speaker for wall-mounting with commer-
cially available speaker mounts or brackets. The speak-
ers require M5 (5 mm) screws. Refer to the manual 
supplied with your mounts or brackets for installation 
details.
Note:
The portion of the screw that 
goes into the speaker’s 
threaded insert should be 
between 5–8 mm long.
Connecting the Power 
Cord
Notes:
• Before connecting the power cord, connect all of your 
speakers and AV components.
• Turning on the SKW-150X may cause a momentary 
power surge that might interfere with other electrical 
equipment on the same circuit. If this is a problem, 
plug the SKW-150X into a different branch circuit.
Adjustment
To set the level of the subwoofer, use the OUTPUT 
LEVEL control. Set it so that bass sounds are evenly bal-
anced with the treble sounds from the other speakers.
Because our ears are less sensitive 
to very low bass sounds, there’s a 
temptation to set the level of the 
subwoofer too high. As a rule of 
thumb, set the subwoofer level to 
what you think is the optimal level, 
and then back it off slightly.
