Product Overview
The KEF Ci160.2CS is a high performance shallow mount
speaker designed for ush mount in-ceiling installations. It’s
a coincident point source design featuring KEF’s proprietary
Uni-Q® technology with a driver array that includes a 16mm
high frequency aluminium dome tweeter mounted in the
acoustic centre of the 160mm low frequency woofer. The
tweeter features KEF’s Tangerine Waveguide engineered to
enhance high frequency dispersion and when combined with
the Uni-Q array, creates a speaker that delivers exceptionally
smooth and consistent sound across a wide listening area.
The KEF Ci160.2CS is constructed using weather resistant
components and the Ultra-Thin Bezel and grille are treated
with a UV protective coating making this speaker ideal for
background, foreground, and anouncement applications in
indoor and outdoor venues such as hotel rooms, corridors and
school hallways.
Key Features
KEF Uni-Q® Technology – This proprietary driver array places
the tweeter in the acoustic centre of the woofer delivering wide
dispersion with consistent sound characteristics throughout the
space. Because the high and low frequencies originate from the
same point, acoustic lobing problems common to other speaker
designs are virtually eliminated allowing fewer speakers to
deliver smooth coverage across a wider listening area.
Tangerine Waveguide – In addition to protecting the driver, the
Tangerine Waveguide further enhances dispersion allowing for
120 degrees of coverage.
Weather Resistant – Manufactured using a proprietary plating
and powder coating process, the KEF Ci160.2CS is UV
protected and designed to withstand the harshest operating
environments.
Ultra-Thin Bezel (UTB) – To maintain a premium aesthetic
appearance, the ABS bezel was carefully engineered to be as
thin as possible while maintaining the necessary structural
rigidity.
Magnetic Grille – For security and ease of installation the grille
attaches by a powerful magnetic circuit and can be painted to
match any décor.
Covered Crossover Circuit – The cover adds structural rigidity
to the speaker assembly while protecting the electrical
crossover components from potential damage.
IP64 Certication – The speaker passed ocial IEC testing to
ensure that splashing water would have no harmful eects on
assembly components.
Architect and Engineer Specifications
The speaker shall be designed for in-ceiling installations and
utilise a coincident point source design with the high frequency
tweeter mounted in the acoustic centre of the low frequency
woofer.
The speaker shall consist of a 160mm low frequency woofer
and a 16mm aluminium dome high frequency tweeter featuring
a waveguide for improved dispersion. It shall be mounted in
a UV protected ABS bae with a paintable bezel of no more
than 5mm in width. The grille shall also be paintable, include a
paint shield, and attach by a powerful magnetic circuit for ease
of installation and security. The speaker shall be available with
an optional rear enclosure and be IP64 certied. Without the
rear enclosure, the speaker shall deliver a minimum frequency
response of 52Hz - 20kHz +/- 6 dB, have a mounting depth of
no more than 85mm, and a weigh of no more than 1.7kg.
The nominal impedance of the speaker shall be 8 ohms and it
must achieve a minimum pressure sensitivity of 89 dB SPL at
1 meter on-axis with an input of 2.83 volts. The crossover
frequency between the woofer and tweeter shall be 2.8kHz.
The speaker shall meet numerous safety and performance
standards listed by regulatory bodies around the world.
Universal cut-out – All KEF 160mm in-ceiling square speakers
utilise the same opening for ease of installation and exible
component selection.
The speaker shall be the KEF Ci160.2CS.
