Operating the device
The Onyx subwoofers can be used for different purposes, but it's important to be aware of the following
information beforehand in order to achieve optimal performance.
Warning before use
Devine's Onyx subwoofers are capable of producing volume levels that can cause temporary or permanent
hearing damage. Use these units with care and keep the volume at a reasonable level when possible. The
volume should ideally be set to a comfortable level when listening to music.
Devine cannot be held liable for any injuries or damage resulting from the use of this product.
General use
Housing
The Onyx subwoofer has a robust housing with a wooden frame and internal bracing to give it added
strength. The exterior has been given a special coating to protect it from light impacts and help prevent
scratches.
During use, storage and transport, ensure that the subwoofer cannot fall or be damaged by nearby objects
that could fall or move.
Handles
The Onyx subwoofers are equipped with handles on the side. With the exception of the 18-inch model, they
have one handle on each side. Due to its size and weight, the 18-inch subwoofer is equipped with two
handles on each side.
The handles make it easier to pick up and move the subwoofer. It's possible to stack up to two subwoofers
on top of another one for a maximum stack of 3. It's possible to use harnesses or tension straps when
moving the subwoofer but please be aware that this may damage the finish on the handles.
Wheels
The 15-inch and 18-inch subwoofers are equipped with screw threads and bolts for mounting wheels.
Standard 80 or 100 mm wheels from any reputable supplier can be used so long as they have bolt holes
measuring 80 x 60 mm. Fixed or swivel castors are both suitable, with or without brakes. We recommend the
use of wheels with brakes so that the wheels are fixated during use and won’t make unnecessary noise
during use.
Whenever the subwoofer is transported in a vehicle like a car, bus or truck, we recommend placing it on its
feet to prevent it from moving.
If you do not want to attach wheels to the subwoofer (because it will be placed in a permanent location, for
instance), we recommend leaving the bolts in place to prevent holes in the housing which will cause
additional air displacement.
Protection during transport
While the Onyx subwoofers can be transported, they are not waterproof and caution is therefore advised if
they taken outside during rain or in adverse weather conditions. If they are exposed to moisture in any form,
ensure that they are completely dry again before use. Failure to do so may result in a short circuit which
could cause permanent damage or injury. Exposure to moisture can also cause visible or invisible corrosion
which may cause damage in the long term.
Grille
The Onyx subwoofers are equipped with a metal grille on the front to protect the speaker components
behind. There is also acoustic foam behind the grille to prevent any unwanted matter from getting inside the
speaker. The grille should therefore not be removed.
