Wall Clamp Mechanism
The clamping mechanism has been designed to provide an acoustically-optimum
bond to the wall surface without risk of distortion to the loudspeaker baffle.
As these screws are tightened, the immensely strong polycarbonate clamping
arms will automatically swing round into the locking position, locating the
subwoofer frame securely to the inside of the back can or wall surface (Fig. 12).
The design also allows for simple removal of the subwoofer frame.
The clamp mechanism ensures that as the screws are loosened
(turned anti-clockwise) the clamp arm travels along its guide before turning
itself into the rest position. The captive locking system ensures that the clamp
arm cannot drop off the end of the screw to be lost in the back can or wall cavity.
CAUTION: Move all the clamps in the rest position by loosening all screws before
attempting to remove the frame assembly from the wall.
Painting
Before proceeding with the installation of the subwoofer assembly into the
installed frame, the grille and frame trim edges can be painted to blend with the
surrounding decor.
It is strongly recommended that the metal perforated grille is sprayed, as this
will avoid clogging of the holes. If painting with a brush is the only option, then
several thin coats of paint will provide a superior finish to that achieved by one
applied too thickly.
The subwoofer is supplied with a paint mask.
1. Press the painting mask into the installed frame. This is left in place while the
wall and frame surround is painted (Fig. 13).
2. The painting mask can also be left in place to prevent dust and dirt
entering the back can or wall cavity, until the subwoofer assembly is ready
to be installed.
Subwoofer Installation into the Frame
With the subwoofer frame installed and the wall and frame finished and painted,
the subwoofer assembly can now be wired and installed into the frame.
Wiring
WARNING: To avoid potential damage to your loudspeaker, ensure that the
amplifier is switched OFF prior to connecting or disconnecting any cables.
WARNING: Before switching the amplifier ON, double check that all connections
are secure and that the polarity is correct.
We recommend the use of insulated speaker wiring of between 12 and 18 AWG.
1. Remove the paint mask from the frame and pull out the end of the speaker
cable. Strip o approximately 8 mm (¼ ") of the outer protective layer from
each conductor.
2. Hold the subwoofer assembly up close to the installed speaker frame.
3. Insert the speaker wires into the correct speaker terminals and secure the
connections with a small screwdriver. The positive wire from your ampli er
should go to the positive terminal marked (+). The negative wire from your
ampli er should connect to the negative terminal marked (-) (Fig.14).
4. Make sure that the speaker cable is secured so that it will not move and touch
the subwoofer cones in operation.
Subwoofer Installation
1. The subwoofer assembly can now be added into the frame, taking care not
to trap or pinch the speaker wiring, or your  ngers (Fig. 15). The subwoofer
assembly only  ts into the frame in one way. The Tannoy brand badge is at the
bottom and the top of the frame is marked "TOP" on the rear.
2. Secure the subwoofer assembly to the frame with the 6 hex screws. To remove
the subwoofer, undo these screws and make sure to support the weight of the
subwoofer assembly as it comes undone.
Grille Installation
1. The grille should be carefully  tted by lining up the edges of the grille with the
ba e and frame inside edges (Fig. 16). To avoid indentation damage, do not
press the centre of the grille; apply even pressure to each corner as it is pressed
 rmly into position.
2. To remove the grille, loop an opened paper clip or similar length of firm wire,
through two holes near a corner and pull gently. The grille is intended to be
a tight fit, so insert the wire at each corner in turn, pulling carefully to avoid
distortion of the mesh.
System Testing
1. Switch on the ampli er with the volume control at its lowest setting. Select
a suitable low frequency signal source and slowly turn up the volume to a
low level. Check that both subwoofer drivers are working correctly - if not,
switch o the ampli er and recheck the connections.
2. Carefully check the area surrounding the installation and listen carefully
to ensure that there are no buzzes or rattles that could potentially impair
enjoyment of the system. If there are, then locate and silence the causes using
cable ties, suitable packing material, or extra adhesive in areas.
