CMSUB8
Features
The APart CMSUB8 stereo ceiling subwoofer is designed to reproduce a fat and
deep bass.
Featuring dual 8 ohms coils and incorporated passive filter circuitry, the
CMSUB8 can be used in almost any situation where extra bass is needed at low
to medium sound levels.
This subwoofer is the ideal partner for all kinds of satellite speakers: small
to medium APart CM speakers (CM3T, CM4T, and many others) but also small
cabinet speakers, such as the APart MASK4(T).
Due to the aluminum grille, this speaker is also suitable for use in humid
conditions.
Ideally, you should use the CMSUB8 in an active configuration, for example
using our Champ-4 amplifier with integrated active low- and highpass filters.
In case you use the CMSUB8 in passive speaker systems, make sure the satellite
speakers have their own highpass filters, for optimum blending with the CMSUB8
speaker.
Furthermore, due to its discrete design, looking exactly the same as many of
our CM speakers, you can enjoy high-quality background music with plenty of
basses. If you need more bass, or when the room is acoustically troublesome,
you should add more CMSUB-8 speakers and spread them across the area. The
speaker is designed for infinite baffle use (e.g. into a ceiling), meaning
that you don’t need to build a back box! When built into an enclosure (e.g.
furniture), then we recommend a closed box with a minimum of 20 liters of
volume.
This speaker is NOT magnetically shielded, so if you have a CRT screen, place
the speaker at a sufficient distance from the screen. Modern plasma, LCD, TFT,
or LED screens are insensitive to magnetic interference, so you can install
this speaker close to such devices without limitations.
For possible and supported speaker/amp combinations, ask your dealer or take a
look at our speaker sets on our website: www.apart-audio.com
Unpacking
This speaker has been carefully packed at the factory. Open the carton box and remove the speaker from the packing. Do not use sharp objects to remove the protective bag from the speaker. When the product shows signs of damage caused by transportation, contact your dealer immediately. Damage due to transport and rough handling is not covered by the manufacturer’s warranty.
Mounting
We recommend using the subwoofer mounted in a ceiling. The speaker is designed
for infinite baffle use (e.g. into a ceiling), meaning that you don’t need to
build a back box!
When built into an enclosure (e.g. furniture), then we recommend a closed box
with a minimum of 20 liters of volume.
The loudspeaker is easy to install, due to its simple, quick mounting system :
3 screws are hidden behind the loudspeaker grille, which gives the loudspeaker
a modern and striking design.
Cutout Ø: 226 mm
Remove the grille before mounting. Behind the grille, you see three Philips
screws.
Use these screws to tighten the dog ears (mounting clamps).
Caution: SAFETY FIRST !!! Some ceiling materials are very soft and might break
under the constant stress of a low-frequency loudspeaker. In case of doubt,
reinforce the ceiling around the speaker!
