-
Avoid using amplifiers that have significantly lower RMS output values than the RMS
input rating of the subwoofer. This can result in the amplifier producing distortion as
it is being worked very hard. This means that the audio is distorted before it reaches
the subwoofer and can damage the subwoofer permanently.
Mounting Instructions
As illustrated to the right of this text, the TL-1121 subwoofer
can be mounted either inside the enclosure facing outwards
(top diagram) or outside the enclosure facing inwards
(bottom diagram).
Position the woofer in place and mark the position of the
mounting 8 points onto the enclosure. It is advisable to use a
1 or 2 mm drill bit to make “pilot holes” before replacing the
woofer and using self-tapping screws (not supplied) to secure
the woofer in place. If mounting the woofer inside the box, it
is important to ensure the audio leads are connected to the
woofer before securing it in place.
