Vertical position

In this position, the subwoofer 

stands upright with its weight 

supported by the floor, with one 

foot bracket mounted at the 

bottom, and two rubber snap 

mounts at the top to prevent it 

tipping forward.

The vertical mounting procedure is as 

follows:

1.  With the help of an assistant, gently 

hold the subwoofer vertically.

.  Secure the two rubber 

plugs to the topmost pair 

of holes, 

2

 and 

3

. Use 

the supplied screws with 

threaded holes in the top of 

the head.

3.  Add a foot bracket to 

the bottom hole 

6

.

4.  Screw a conical striker 

into the threaded holes 

in the heads of the 

screws holding the plugs 

onto the subwoofer. 

5.  Move the subwoofer with its back to 

the wall, with the weight resting on 

the foot bracket on the floor. Make 

sure it is vertical. Do not let go of 

it, or it will tip over and may cause 

damage or injury.

6.  Gently press the subwoofer back 

against the wall, just enough to 

leave two marks with the conical 

strikers. These marks are used as 

guides to fitting the corresponding 

rubber cups to the wall.

7.  Move the subwoofer to one side, 

and remove the two conical strik-

ers. They are no longer needed, 

but keep them in a safe place.

8.  Drill two holes into the drywall at 

the marks, and gently tap in the two 

drywall anchors until they are flush. 

(Do not use anchors if the holes fall 

on a stud location.)

9.  Secure the two 

rubber cups to the 

drywall anchors 

using the supplied 

screws. (Or use the 

supplied lag bolts if the holes fall on 

a stud location)

10.  Connect your speaker wire to the 

subwoofer terminals.

11.  Move the subwoofer back to this 

position, up against the wall, and 

press it backwards until each rub-

ber plug on the subwoofer fits into a 

rubber cup on the wall.

1.  Check that the subwoofer is 

standing vertical, parallel to the 

wall, i.e. not tipped out or in from 

the wall, and check that the plugs 

are securely pressed into the wall 

mounted cups. 

Do not allow children or anyone 

to pull on the subwoofer, as it may 

pop out and tip over.

Note: If you have masonry walls then 

contact your local hardware store 

for suitable hardware to hold the 

rubber cups securely onto the wall.
