The CELO series is AUDAC‘s high-end, slim ceiling speaker
series, comprising different models which can guarantee an
optimal experience for every situation and application. The
ultra-compact size enables the CELO2 to smoothly integrate
into any interior like no other loudspeaker. The outer diameter
only measures 118 mm, which is as compact as a standard
down lighter and the built-in depth of 95 mm allows installation
in any ceiling while being unobtrusive.
CELO2
High-end ceiling speaker 2"
The sound originates from a 2” aluminum cone driver which
provides a full-range, warm and detailed sound with an
improved response in the low frequencies due to a ported
enclosure with closed back can. This way, a smooth sound
reproduction with clear and crisp sound is guaranteed. An
internal self-resetting network provides an optimal overload
protection. All these details share their part to the quality of the
CELO2, resulting in a highly reliable loudspeaker producing a
pure sound with a maximum power handling of 20 Watt and an
RMS power handling of 10 Watt.
An elegant look with minimal visual impact is created by the slim
grill with very thin border of only 1 mm. To make them blend in
even more, the grill can be painted in the same color as the
surrounding surface or an optional black grill (GLC02/B) will
provide seamless integration in dark environments. The elegant
and unobtrusive grill is held in place by means of powerful
neodymium magnets, making assembly and disassembly very
simple but still reliable enough to keep the grill in place during
the complete lifetime of the loudspeaker.
Secure mounting and easy installation is guaranteed using the
quick-fix mechanism which can be tightened by two screws and
the Gold-Con™ spring clamp connectors. The grill is held in
place using neodymium magnets, providing a quick and reliable
assembly. stable assembly.

Architects’ and Engineers’ Specifications:
The ceiling mount loudspeaker shall be a full range type fitted in a closed ported enclosure and equipped with a 2'' aluminium cone
driver with neodymium magnet. It shall have an RMS power handling of 10 Watt with a maximum power handling of 20 Watt and the
frequency response (±3 dB) shall range from 120 Hz to 20 kHz. The sensitivity shall be 83 dB when measuring with an input signal of
1 Watt at a distance of 1 meter, while the maximum continuous sound pressure level shall be 93 dB. The nominal dispersion shall be
a 165° conical coverage pattern at -6dB (average 100 Hz - 10 kHz). The loudspeaker shall have an impedance of 8 Ohm and shall
contain an internal self-resetting network which provides an optimal overload protection. The speakers construction shall be made
out of high-quality ABS with a black colour and textured matt surface finishing. A 2-screw quick-fixing mechanism shall allow
assembly of the speaker into a ceiling in a fast and productive way while the connectivities are performed using Gold-Con™ spring
clamp connectors. To make the loudspeaker nearly invisible when mounted, the speaker shall have a white (RAL9003) grill with a very
thin border of 1 mm which extrudes the ceiling surface by only 3.2 mm. This grill shall be constructed of steel which can be painted
to make it blend-in with any environment. The assembly and disassembly of the grill shall be very simple thanks to the neodymium
magnets holding it in place. The speaker shall have a diameter of 118 mm, a depth of 98 mm and shall not exceed 0.35 kg. The
speaker shall fit in a mounting hole with a cutout diameter of 100 mm and a build-in depth of 95 mm.
