Operating the device
The Onyx speakers 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
The Devine Onyx passive subwoofers are not equipped with a built-in filter or crossover. These subwoofers
are not suitable for full-frequency (20 - 20,000 Hz) reproduction.
Always use an external signal processor or crossover to ensure that only low frequencies are sent to these
subwoofers.
Devine Onyx passive subwoofers perform best with frequencies between 30 and 350 Hz approximately.
Because each setup is likely to be slightly different, it's worth experimenting a little with various crossover
settings to see which one gives best results.
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 subwoofer won't move and possibly 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 speakers 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.
The information in this user manual is subject to change at any time without notice.
